Preparing the surface for application

Prepare the surface for application of the material: remove loose areas, open cracks, remove oily inclusions, clean the concrete from cement laitance, repair the surface, including inter-brick joints to reduce material consumption and excavations deeper than 5-7 mm, with cement-plaster compounds. Clean the surface using a sandblaster, a metal brush or abrasive wheels for removing gloss on surfaces and removing falling off and crumbling structural elements.

After mechanical treatment of the surface, thorough dust removal should be carried out using brushes or blowers. After dust removal, the surface must be washed with water to remove dirt, remaining dust, etc. Wait until it dries completely. Concrete, brick and similar surfaces must first be primed with YAKHONT deep penetration primer. If it is necessary to apply the CORUND FACADE coating to metal surfaces, the metal must first be protected from corrosion.

It is recommended to first apply 1-2 layers (0.5 mm each), depending on the condition of the metal surface, modification CORUND Anticor. Concrete humidity when applying CORUND FACADE should not exceed 4%, air humidity during application should not exceed 80%. If there are oily and greasy stains on the surface, they must be removed with a solvent.

Preparation of insulating coating CORUND FACADE

CORUND FACADE is ready for use; it must be mixed, if necessary, adding a little distilled water, immediately before application to a previously prepared surface. The amount of water also depends on the temperature of the application base and subsequent use. When applied to a surface with a temperature from +7°C to +80°C, the amount of water added to the material can be no more than 5% when applied with a brush and no more than 3% when applied mechanically (airless spraying apparatus). When applied to surfaces with temperatures above +80 °C, it is necessary to first reduce the temperature by applying several primer layers of CORUND FACADE material, diluted with 40-50% distilled water according to the scheme (see coating application). If the storage period is long, separation into fractions inside the container is allowed.

Do not over mix! When using a drill with a paddle attachment or a mixer, the maximum permissible mixing speed is 100 rpm. Exceeding the rotation speed will lead to the destruction of the microsphere and a radical reduction (or cancellation) of the effectiveness of the thermal insulation coating. Using vertical movements of the blade to immerse the thickened part in the liquid, turn on the drill and slowly begin to rotate the blade, mixing the curds with the liquid.

Stir until the product resembles cream. Approximate mixing time:

Mixer 3-8 minutes,
Manual stirring for 7-10 minutes.

If the task is to eliminate condensation, a “coat” of frost, fungus, mold, the material is applied with a minimum addition of water, with a maximum interlayer interval (over 24 hours).

Coating

It is recommended to work with Corundum Facade using a soft brush with long natural bristles or an airless spray. You can apply the coating to small surfaces or areas with complex configurations using a soft brush. Surfaces from 100 m2 can be treated using an airless sprayer with a material pressure at the nozzle exit of 60-80 bar

Important: not all airless sprayers are suitable for working with Corundum Facade paint!

The insulating coating can be applied to surfaces with temperatures from +7ºС to +120ºС. You cannot work in wet weather, because... The material is liquefied by water and will not dry out. The period for complete drying of one layer of coating with a thickness of 1 mm is at least 24 hours. The next layer can be applied only after the previous layer has completely dried - after 24 hours at a temperature not lower than +7°C during the entire drying period. A layer of about 1 mm is obtained with approximately three to five “passes” of the sprayer or brush. Applying the material in a thicker layer is unacceptable, since this leads to the formation of a moisture-proof film on its surface, which in turn prevents the complete evaporation of the moisture contained in it, which will lead to the annulment of the thermophysical properties and deformation of the coating.

When applying the material to a surface with a temperature above +80ºС, the material boils and “sets” very quickly, so the material must be diluted with water. It is recommended to prime the surface with a 40-50% aqueous solution of the material. When applying CORUND FACADE on surfaces with temperatures above +80 °C, the thickness of the maximum layer within 24 hours should not exceed 0.5 mm! The hotter the application surface, the more the material is diluted. The diluted material is applied with quick short movements; with this application the layer will be very thin. The drying time for each layer is at least 1 hour. Such layers are applied until the applied material stops boiling on the surface. After this, allow to dry for 24 hours. Then the material is applied according to the usual scheme - with the addition of 3% to 5% distilled water in layers up to 1 mm with interlayer drying for 24 hours. The thickness of a layer of 1 mm can be determined by a thickness gauge of the “painting comb” type, a material consumption of 1.1 liters per 1 m2 (approximate consumption when applying the coating with a brush on a flat surface) or a thickness of “» material (so that the underlying material does not show through). The material consumption is affected by the type of surface and method of application. The total thickness of the coating and the number of layers are determined by thermal engineering calculations.

Safety precautions when working with CORUND FACADE

At normal conditions the product is safe. If the room is well ventilated or work is carried out outdoors, respirators are not required. In rooms without ventilation, use standard respirators. Use safety glasses to protect your eyes. Use gloves and protective clothing to protect your skin.

If the product gets into your eyes, rinse your eyes immediately. running water within 15 minutes. If irritation persists, consult a doctor. In case of contact with skin, wash with soap and water.

The product in liquid state is not flammable. In the event of a fire in structures or structures on which the coating has been applied, use water, foam, dry chemicals and carbon dioxide. In case of product spillage, use any absorbent material such as sand, soil, etc.

Storage and transportation conditions

The CORUND FACADE material is stored in tightly closed containers at temperatures from +5 °C to +30 °C, air humidity no more than 80%, away from direct sun rays. Transportation is carried out by any type of transport at temperatures above +5 °C away from direct sunlight. Packaging of cargo for transportation must ensure the correct installation of containers and the safety of the container. Violation of the integrity of the container leads to damage to the material.

LLC “RESEARCH AND PRODUCTION ASSOCIATION FULLERENE” offers you liquid ceramic heat-insulating material CORUND, which is superior in its thermophysical properties to well-known analogues. Own production, high-quality imported raw materials from leaders in the chemical industry, allows us to offer our customers an exclusive line of modifications of ultra-thin heat insulators.

The material CORUND has a full package of necessary certificates and fully complies with the declared technical parameters.

CORUND consists of a high-quality acrylic binder, an original developed composition of catalysts and fixatives, and ceramic ultra-thin-walled microspheres with rarefied air. In addition to the basic composition, special additives are introduced into the material, which eliminate the appearance of corrosion on the metal surface and the formation of fungus in conditions of high humidity on concrete surfaces. This combination makes the material light, flexible, stretchable, and has excellent adhesion to the surfaces being coated. The consistency of the material is similar to regular paint, is a white suspension that can be applied to any surface. After drying, an elastic polymer coating is formed, which has unique thermal insulation properties compared to traditional insulators and provides anti-corrosion protection. The unique insulating properties of Corundum are the result of the intense molecular action of rarefied air located in hollow spheres

Corundum material is highly effective in thermal insulation of building facades, roofs, internal walls, window slopes, concrete floors, hot and cold water supply pipelines, steam pipelines, air ducts for air conditioning systems, cooling systems, various containers, tanks, trailers, refrigerators, etc. It is used to eliminate condensation on cold water supply pipes and reduce heat loss in accordance with SNiP in heating systems. The material is used at temperatures from - 60 C to + 260 C. The service life of the material, subject to the rules of application technology, is at least 15 years. Today, our material is used at facilities and enterprises in various fields of activity.

How does the material work from the point of view of thermophysics?

Let's start with the fact that there are three ways to transfer heat:

1. Thermal conductivity - the transfer of heat in a solid body due to the kinetic energy of molecules and atoms from a more heated to a less heated part of the body.

2. Convection - transfer of heat in liquids, gases, granular media by flows of the substance itself.

3. Radiant heat transfer (thermal radiation) - electromagnetic radiation emitted by a substance and arising due to its internal energy.

Thermodynamics is a science that studies the laws of mutual transformation and transfer of energy. The result of these processes is temperature equilibrium throughout the system.

The method and effectiveness with which the insulating material blocks heat redistribution, i.e. the process of temperature equilibrium, determines the quality of the insulation.

Heat transfer is convective or radiant heat exchange between the surface of a solid and the environment. The intensity of this heat exchange is characterized by the heat transfer coefficient.

Liquid ceramic heat-insulating material CORUND is a complex, multi-level structure in which all three methods of heat transfer are minimized.

A ceramic heat insulator consists of 80% microspheres; accordingly, only 20% of the binder can conduct heat due to its thermal conductivity. The other share of heat comes from convection and radiation, and since the microsphere contains rarefied air (the best insulator after vacuum), heat loss is not great. Moreover, due to its structure, the material has low heat transfer from the surface, which plays a decisive role in its thermophysics.

Thus, it is necessary to separate two terms: Insulation and Heat Insulator, since in these materials the physics of the heat transfer process is different:

▪ insulation- the operating principle is based on the thermal conductivity of the material (min. plate)

▪ heat insulator- mostly on the physics of waves.

The effectiveness of insulation directly depends on the thickness: the thicker the insulation layer, the better.

The thickness of the thermal insulation layer of the ultra-thin heat insulator KORUND varies from 1 to 6 mm, a subsequent increase has virtually no effect on its effectiveness.

Today, Corundum has the following industrial modifications -

1. Corundum Classic.

The basic modification is the best liquid thermal insulation. It is a film-forming modification that allows you to insulate objects with surface temperatures up to +200 °C on a permanent basis.

2. Corundum Facade.

For the first time in the world, a material has been developed that can be applied in layers up to 1 mm thick at a time, and has increased vapor permeability.

3. Corundum Anticorrosive.

For the first time in Russia, a unique material has been developed that can be applied directly to a rusty surface. It is enough to simply remove the “damp” (loose) rust with a metal brush, after which you can apply CORUND Anticor thermal insulation, following the instructions.

Thermal insulation Corundum Anticor is a highly effective thermal insulation coating with additional anti-corrosion properties, and not just a preservative and corrosion modifier. All technical characteristics, requirements, instructions for use are the same as for the base material CORUND. The use of CORUND Anticor for thermal insulation of existing structures and pipelines significantly reduces labor costs, since it does not require special preparation of the working surface. Thermal insulation Korund Antikor must be applied as the first layer, and for subsequent layers (in order to save money) you can use “classic” thermal insulation KORUND.

4. Corundum Winter.

For the first time in Russia, a material has been developed that can be worked with at subzero temperatures. Corundum Winter is the latest development in the line of ultra-thin liquid ceramic heat-insulating materials. Unlike all other gastrointestinal materials presented on the Russian market, work on applying Corundum Winter can be carried out in winter, while the minimum application temperature for conventional gastrointestinal materials cannot be lower than +5 ° C Corundum Winter consists of a composition of special acrylic polymers dispersed in it contains foam glass microgranules, as well as pigmenting, fire retardant, rheological and inhibitory additives.

Now you are not afraid of the “winter recession” in construction!

The Russian market currently offers liquid ceramic heat-insulating materials that find their consumers due to their wide range of applications and ease of use with low labor costs. Since the materials offered are mainly produced abroad, they have a high cost, which limits the possibility of their mass use in construction, energy and housing and communal services, etc. While domestic analogues often leave much to be desired, both in terms of “quality” and extremely high markups for “know-how” cause negativity and bias among the end user towards liquid ceramic thermal insulation materials. Liquid composite thermal insulation material CORUND ® is the first product developed in Russia using original technology, made from high-quality imported components and has no analogues in terms of price-quality ratio. The production of CORUND ® is fully certified, which guarantees consistently high quality of the product. Pride in our product is formed from positive assessments and gratitude from our customers. Our clients appreciate the impeccable declared and guaranteed functionality and turn to us again and again. We are proud of the quality of CORUND ®.

Corundum - Thermal paint developed by Russian specialists and a new word in thermal insulation of any surfaces. Some types of this paint work even at temperatures above 500 degrees. And all because the material is not flammable.
Easy to apply, Corundum is a thermal insulation that lasts a long time, from 15 years, and replaces in terms of thermal stability additional wall one and a half bricks.
Thermal paint is a unique development that gives protective properties walls of buildings, facades, concrete slabs. By using corundum paint, you save money on thermal insulation.

In terms of its composition, it is a suspension, water-based or varnish-based, which covers various surfaces well, even with unevenness. The consistency of the paint is pasty, the color is gray or white. It is convenient to work with a brush, roller or spray. The thicker the thermal paint, the higher the thermal protection. Its service life is from 15 to 40 years.

Insulation paint is multifunctional. It retains heat well, prevents water from penetrating into structures, and protects against the formation of mold. Corundum thermal insulation extends the service life of pipes, tanks, refrigeration equipment, and air conditioners. Retaining heat is the main purpose of thermal paint, so it is indispensable for thermal insulation of pipes. The materials currently used are short-lived and harmful to humans. Pipes coated with corundum thermal insulation withstand the effects of precipitation and sunlight.

According to sad statistics, a huge number of fires occur due to the fault or direct participation of heat-insulating materials. Often the walls are lined with flammable thermal insulation, and in the event of a fire, the fire with lightning speed, with the help of this insulation, spreads throughout the entire building, spreading to the roof and neighboring entrances. To prevent this from happening, use heat paint. This is an inexpensive material that is safe in all respects and does not support combustion.

Liquid thermal insulation Korund has undergone climatic tests, which have shown that the protection effectiveness of products coated with the composition remains for at least 10 years.

Thus, ultra-thin thermal insulation Corundum is an effective technological material that meets all the requirements for this class of thermal insulators. Among its disadvantages, it can be noted that while it has the performance characteristics inherent in all ultra-thin insulations, it has the disadvantage of a higher price.

An innovative material that appeared relatively recently, but has already managed to attract a lot of attention to itself. Why? Liquid foundation ceramic thermal insulation Corundum changes the idea of insulating materials after the first use. The substance forms a fairly thin film, which has protection from aggressive environments and a minimum thermal conductivity. An interesting point is the weight of the thermal insulation material before and after application. When the composition dries, its weight decreases to an insignificant figure and is almost unnoticeable.

The use of a material such as liquid ceramic thermal insulation Corundum has very specific goals:

Protection from external factors and preservation of integrity;
Insulation of pipeline systems;
Thermal insulation of the room.

The Korund company has made sure that its products are as effective as possible for its customers, introducing the following products to the market:

Classic

It has multifunctional properties and is resistant to temperature variations (-60/+200 °C) and can withstand short-term critical temperature points (up to 260 °C). Designed specifically for insulating the main elements of a building: water supply, heating boiler, walls, openings, facade finishing and other partitions that protect the room from climatic conditions.

Facade

This thermal insulation from Korund is designed to insulate the facade of a room (residential or not, it doesn’t matter). It has good adhesion to many surfaces, that is, high-quality use is available with almost any facing material. It has a high level of resistance to weather vagaries and retains more heat generated in the room compared to foam insulation.

Anticorrosive

A unique coating to protect and prevent the effects of rust. Possesses high rate in terms of resistance to corrosion. The mixture was received wide application for thermal insulation and protection of reinforced concrete and metal structures, pipes that are used everywhere, as well as other metal products used in construction. It boasts the ability to apply the mixture to the surface without first removing traces of plaque and rust.

Winter

An insulating coating that is designed for conditions with low temperature properties. Thanks to its special composition, it is resistant to adhesion to surfaces after application. Including those surfaces that have a different base - liquid and solid. In addition, this coating protects well from the effects of alkali, salts and many acids.

Use of liquid material - ceramic thermal insulation Corundum

The use of such a heat insulator does not require special expensive tools. A standard pneumatic spray gun works well. It is also possible to work with such improvised tools as a roller and brush. The application itself is simple and fast. The coating that forms the heat insulator from Corundum is smooth and seamless. This property has a good effect on heat retention.

Liquid thermal insulation Corundum is a kind of coloring material, after application of which a high-quality ceramic thermal insulation layer is formed on the surface, which also protects the surface from negative impact corrosion.

What is liquid thermal insulation Corundum

Do you need to carry out internal thermal insulation of the walls of the room, while you want to lose a minimum of free space? Or do you need to insulate the walls from the outside, but at the same time you want them not to lose the attractiveness of their appearance and so that a minimum of money is spent on such insulation measures? Then the only correct solution would be to use liquid thermal insulation Corundum.

Residents of our country have been living in houses with uninsulated walls for many years. And all this because they are afraid of the long, labor-intensive and expensive process of insulation. But today there is a material that can effectively, quickly and inexpensively solve this problem. And this material is liquid Corundum thermal insulation. If you go to hardware stores, you can find a lot of ceramic-based thermal insulation materials. But relatively recently, scientists have developed a thermal insulation material that is better in its technical and operational characteristics than analogue materials, while its cost is no different.

Scope of application of liquid thermal insulation Corundum

Due to the fact that Corundum thermal insulation has a liquid consistency, it has many advantages over its direct analogues, since it can be applied to a wide variety of surfaces:

roof;
Window slopes;
Pipes;
Building facades;
Various types of containers;
Internal and external walls;
Cooling chambers.

In order to prevent any condensation from forming on the surface of the pipeline, and to ensure that hot water reaches you with minimal heat losses, it is recommended to treat the pipes with liquid thermal insulation Corundum. The duration of the operational period of such a coating is equal to 15 years, such thermal insulation can withstand significant temperature changes from -50 to +250 degrees, no analogue can boast of such technical and operational characteristics, and this is subject to the relatively low cost of the material.

Advantages of liquid thermal insulation Corundum

The main advantages of liquid thermal insulation Corundum include the following positive aspects:

The application process can be carried out independently; for this, a regular brush or spray can be used;
Just one millimeter of liquid thermal insulation Corundum will provide the same properties as 600 mm of rolled thermal insulation material;
Considered waterproof and not subject to negative influence saline solution and ultraviolet radiation;
Provides visual access to inspect the isolated surface;
It is a fire-resistant material that does not support the combustion process. When exposed to 260 degrees, the material is charred, but if the temperature rises to 800 degrees, the decomposition process begins with the release of nitrogen oxide and carbon, and these substances stop the combustion process.

Thermal insulation corundum

The ultra-thin liquid ceramic thermal insulation Corundum offered on the market is the optimal solution for many cases in terms of its effectiveness in protecting products, durability, ease of application, but unfortunately not price. Ultra-thin thermal insulation Corundum is a water-based liquid composition, the main component of which is a polymer latex composition. Its scope of application ranges from covering the walls of buildings and structures to thermal insulation of various types of pipelines (air and water pipelines). It is also used for application to various types of industrial equipment.

Properties of liquid ceramic thermal insulation Corundum.

Like all ultra-thin thermal insulations, in addition to direct thermal protection, Corundum also prevents corrosion. In addition, the material has dielectric properties. However, in terms of price-quality ratio, it is somewhat inferior to analogues - for example, Akterm liquid thermal insulation.

Corundum, like all representatives of this class of materials, has a significant advantage over traditional insulation using mineral wool, as it lays down in a continuous layer, leaving no gaps. In the case of mineral wool, there are always unprotected areas that are channels for the flow of heat. In addition, Corundum is very simply and quickly applied to almost any type of surface. In this case, it does not matter much whether it is a plane, a rough wall, or equipment of a complex shape. The composition is applied in an ultra-thin layer, providing maximum thermal insulation; the application process itself is almost similar to conventional painting and does not require much time. The composition can be applied at temperatures down to -10 ° C, which is approximately equal to or even slightly inferior to the similar thermal insulation indicator of Akterm.

Even without special equipment, but simply placing your hand on a wall covered with Corundum, you will feel the warmth, while an unpainted wall will cool your palm.

Corundum – the warmth of your home!

Corundum paint for thermal insulation is a substance with a liquid consistency based on a polymer-latex composite. This material is used today in many areas of activity - from the protection of industrial equipment and pipes to the external and internal thermal insulation of residential buildings. The popularity of this liquid heat insulator is due to its unique performance properties.

Production features and general description

Thermal insulation Corundum is a composition based on ceramic microspheres and an acrylic binder. The last ingredient is produced using catalysts and fixatives.

The size of the microspheres varies from 0.01 to 0.5 mm. The composition of the product is also supplemented with all kinds of additives to enhance its performance properties. This composition gives the material flexibility, lightness and elasticity. In addition, Corundum is characterized by good adhesion to a wide variety of surfaces.

The consistency of this brand of heat insulator resembles ordinary paint. In fact, it is a white suspension, which, after hardening, forms a very reliable and elastic polymer coating.

In comparison with ordinary heat insulating materials, Corundum provides not only protection against heat loss, but also against corrosion.

Initially, such coatings with heat-protective properties were created at the request of NASA for finishing spacecraft. Over time, experts adapted these mixtures for “earthly” needs. Corundum is the commercial name of the product, which was developed by Russian specialists. This heat insulator has special certificates that indicate its high quality.

Types of heat insulators Corundum

Today you can find several modifications of this product on sale. Of these, the most popular are the following formulations:

Specifications

The properties of this material allow it to be used for processing structures for various purposes and different configurations.

The characteristics of Corundum should be considered in more detail:

Advantages and disadvantages of the material

Thermal paint of this brand carefully fills the micropores of the surface that is being processed. In addition, liquid thermal insulation has the following advantages:

This type of isolation is not without its disadvantages. First of all, this concerns high cost. This material appeared on the Russian market relatively recently, which is why it still has a high cost. However, this “minus” is fully compensated by the durability of the coating and excellent thermal insulation properties.

The disadvantages also include the rapid polymerization of thermal paint, so you will have to work with it very quickly.

Criterias of choice

The patent for the material belongs to the Fullerene company. This organization has several official dealers, for example, “ServisInvestProject”, “TeploTrade” and others. You should not buy products from sellers with a dubious reputation.

The normal state of this brand of material is a white pasty mixture. Packaging - buckets made of durable plastic with different volumes. In this case, information about the manufacturer must be indicated on the packaging.

The cost of thermal insulation varies depending on the region of sale and the type of material. The average cost of insulation is as follows:

Classic - 390 rubles per liter;
Anticorrosive - 440 rubles per liter;
Winter - 560 rubles per liter container.

How to work with Corundum correctly

Liquid thermal insulation can be applied with traditional painting tools - a spray gun, roller or brush. The spray gun allows you to achieve the highest quality coating and minimum flow material.

The layer thickness should not exceed 0.4 mm. You need to start applying the next layer only after the previous one has hardened. When used, the approximate consumption of the substance is about half a liter per square meter of surface.

To apply heat paint, you can use the following instructions:

Pour the composition into a separate vessel and mix it until a homogeneous mass is obtained. To speed up and simplify this work, you can use a drill and a special attachment.
Surfaces must first be degreased and cleaned of dust and dirt. If we are talking about a metal alloy, then the surface must additionally be freed from traces of rust. For degreasing, it is better to use solvent, kerosene or gasoline.
Thermal paint should be applied only to dry areas. The thinnest layer is the first one, since it is essentially a primer.
When using a roller or spray, hard-to-reach areas and joints will still have to be painted with a brush.
Experts advise applying no more than three layers of material.

Warm paint Corundum looks very attractive on the surface, and therefore it can even be used for finishing cladding.

Corundum is an innovation in the field of thermal insulation materials. It can be used for effective insulation of buildings for various purposes, pipes and other elements. This is a reliable and completely environmentally friendly liquid thermal insulation.

Opinions on isolation

“I bought material to insulate the trailer in which construction workers lived at the site during the winter. According to reviews, the thermal insulation properties of Corundum suited me perfectly. However, I did not notice the thermal conductivity stated both in them and in the technical characteristics. And so the isolation completely justified itself. It is ideal for those who want to save space when insulating.”

Oleg, Samara.

“They started renovations, the pipes in the apartment were metal, but still quite new. Condensation constantly accumulated on them. The builders advised not to change them, but to cover them with a thin layer of thermal insulation Corundum Anticor. The pipe now looks presentable, and there is no longer any liquid on its surface.”

Evgeniya, Chelyabinsk.

“I painted the walls of an old building with thermal insulation from Korund Facade concrete house. First, I cleaned them of traces of fungus and mold using a grinder with a special brush attachment. The layer was applied quite thick with a wide roller. It took about 2 days to dry, fortunately it was dry and warm outside. The snow-white walls are pleasing to the eye for the second year.”

Corundum – the warmth of your home!


"Classic" - for all surfaces	"Anticor" - for rusty surfaces	"Facade" - for external work

Advantages and disadvantages of the material

The following positive factors can be identified:

excellent “adhesion” to metal, stone and plastic surfaces - there are no air gaps left between the ultra-thin layer of film and the base;
100% water resistance;
"Corundum" is not afraid of temperature changes;
it is possible to process a plane of any shape;
low weight of liquid;
UV resistance;
the material does not support the combustion process.

As for the negative characteristics, this is perhaps the point that this coating is not very resistant to mechanical stress. That is, the plane can be scratched without much effort. However, if we talk about objectivity, it can be noted that the surface is very easy to repair - just apply another layer of liquid to the damaged area.

Well, it's time to touch on the most important issue.

Varieties

Depending on the intended purpose and scope of application, the following brands are distinguished:

1. Classic. Liquid insulation for facades, roofs, external and internal walls, cement floors, slopes, pipeline communications, air conditioning systems, working tanks and vessels. Very light: a 20-liter bucket weighs about 10 kg; after drying, an ultra-thin protective layer (from 0.5 mm) is formed; of all the Corundum brands, this is the most universal.

2. Facade. It is used to protect walls from freezing and condensation accumulation, and prevents the formation of fungus and mold. It is a “breathable” type, retains heat without disrupting air exchange, and helps normalize humidity in the room.

3. Anticorrosive. It has additional anti-corrosion properties and does not require surface preparation before application. First of all, it is used to protect metal communications.

4. Winter. Designed to work with sub-zero temperatures(up to -10 °C), contains foam glass microgranules, dispersed and inhibitory additives.

5. Facade-Lotus. Thermal insulation coating with a self-cleaning effect (the smallest particle structure prevents dirt from sticking). It is recommended for use as a finishing layer for facades, as it repels moisture, raindrops instantly drain from it along with dust. Has vapor barrier properties.

Features of operation

The undoubted advantage of liquid thermal insulation is its ease of application; the process is no different from conventional painting (which allows you to save on the cost of work or carry it out yourself). Special preparation is not necessary, the main thing is that the surface is dry and free of grease; the approximate consumption of liquid insulation Corundum is from 1 to 3.5 liters per 1 m2. Tools required: roller, sprayer (for larger spaces) or soft brush.

The suspension is protected from damage to ceramic microgranules; mixing or grinding of the composition is not allowed; solvents are not added. Corundum is applied in layers (0.3 to 0.5 mm thick), each subsequent one only after the previous one has dried, at least after 18 hours.

Work is carried out at normal humidity and ambient temperature not lower than +5 °C (otherwise the drying conditions will be violated). No personal protective equipment is needed; Corundum thermal insulation is absolutely safe at any stage of operation.

Preparation of the insulating coating.

CORUND NG is ready for use; it must be mixed, if necessary, adding a little water, immediately before application to a previously prepared surface. If the storage period is long, separation inside the container is allowed. **********DO NOT OVERSTIX*********

When using a drill, the maximum permissible mixing speed is 100 rpm. Using vertical movements of the blade to immerse the thickened part in the liquid, turn on the drill and slowly begin to rotate the blade, mixing the curds with the liquid. Stir until the product resembles cream. Approximate mixing time is 3-8 minutes, manual mixing is 7-10 minutes. If the task is to eliminate condensation, a “coat” of frost, the material is applied with a minimum addition of water with a maximum interlayer gap.

Application instructions

Before you start applying Corundum paint, you need to choose the right material. You should not buy products from unverified sellers. The manufacturer is the Russian company Fullerene. In addition, there is a network of distributors

Be sure to pay attention to the condition of the paint. It should have the form of a suspension of paste-like consistency with a whitish tint.

Traditional packaging is a plastic bucket. It can be of different volumes. The label must contain information about the manufacturer.

As for the cost of Corund paint, it differs depending on the type of material and the place where sales are made. For example, in Russia the cost of the Classic modification for 100 ml is approximately 34 rubles. Anticor coating can be purchased for 450 rubles per 1 liter. Corundum costs from 400 rubles per 1 liter, and Corundum Winter - from 550 rubles.

To apply thermal paint, you need to stock up on the appropriate painting tools. This can be a spray gun, roller or brush. It is best to apply paint using the first option, since it not only reduces the consumption of the substance, but also makes the coating better.

The thickness of one layer of paint should be approximately 0.4 mm. The next layers should be applied only after the previous layer has dried. If you use a brush or roller, the average product consumption is approximately 500 ml per 1 m².

Here is the algorithm of actions:

Pour the liquid into a large container and stir well until it has a uniform consistency. To do this, you can use a special drill with a suitable tip. Experts advise setting the machine to medium speed so that the structure of the ceramic microspheres does not deteriorate during mixing.
Clean the surface to which paint will then be applied. Pre-treat with degreasing compounds. To do this, you can use a special solvent. If the surface is metal, then the rust should be removed.
Allow the surface to dry completely before applying paint. The first layer should be minimal in thickness, since it is a primer.
When using a roller or spray gun, you need to carefully handle joints and other places where there is no access. You'll have to use a brush.
It is recommended to do no more than 3 layers of paint for optimal results.
It will take about a day to dry completely. If you paint warm pipes, the paint will dry even faster.

Thermal paint Corundum will look beautiful, so it can be used not only as thermal insulation, but also as a finishing coating.

Brief instructions for applying Corundum thermal insulation

We apply Corundum thermal insulation following these instructions:

Pour the paint into a large container and mix it thoroughly so that the mixture is completely homogeneous. To do this, you can use a drill with a special attachment. You need to set the speed to medium so as not to destroy the structure of the ceramic spheres.
We clean and degrease the surfaces on which we plan to apply Corundum. If it is metal, then we clean it upper layer rust. We use gasoline, kerosene or solvent as a degreaser.
We begin to apply heat paint to completely dry surfaces. The first layer should be minimum thickness, since it is considered a primer.
If you use a spray gun or roller to apply Corundum, then joints and hard-to-reach places will in any case have to be treated with a brush.
If you use Corundum brand “Winter”, then work can be carried out at a temperature not lower than -10 degrees. For other types of liquid thermal insulation, the optimal application temperature is +20 degrees.
It is recommended to create no more than three layers of insulation to achieve optimal results.
It usually takes about a day for all layers to dry completely. If hot pipes were painted, polymerization occurs much faster.

Surface preparation.

The insulated surface must be cleaned of dirt, rust, dust, old paint, remove crumbling elements

Pay special attention to ensure that there is no “loose” rust on the metal in the form of a “fungus”, which, after applying CORUND NG, will peel off from the metal along with the coating. Clean the metal surface from rust using metal brushes or abrasive wheels, removing the loose layer of rust until a metallic shine appears. The rust-free surface is treated with phosphoric acid or a rust converter, kept for 2 hours and then washed with plenty of water.

New metal surfaces may require preservatives to be removed. The finished surface should not contain crumbling elements, should be dry (including not condensing), should not contain oil or greasy elements and should not be overly plastic. If CORUND NG is intended to be used on ferrous metal surfaces, with temperatures from +90ºС to +95 ºС, then the surface must first be dust-free and degreased.**********CHECK THE INTEGRITY OF THE SEALS BEFORE OPENING THE CONTAINER*** *******

Liquid thermal insulation Alfatek

Liquid ultrafine thermal insulation Alfatek is a ceramic multicomponent material based on a polyacrylic system. Liquid thermal insulation Alfatek is a ready-to-use product and is intended for application to surfaces of any configuration that require solving the following problems: thermal insulation building walls - internal and external ultra-thin thermal insulation brick walls; thermal insulation pipes (pipe thermal insulation) - anti-corrosion protection (ultra-thin); reduction of heat loss; eliminating condensation formation; effectively increasing energy saving; anti-corrosion protection; combating freezing of residential walls

Liquid thermal insulation Isollat

Liquid thermal insulation Izollat is intended for coating surfaces of any shape; it has thermal insulation and anti-corrosion properties with a very wide range of applications.
Liquid thermal insulation Isollat can be used for thermal insulation of pipelines, hot water, water heating equipment for boiler houses; to reduce heat losses during capital construction and during the reconstruction of public and industrial buildings; to combat freezing of residential walls; to prevent the formation of ice and icicles on roofs; to reduce cooling costs and prevent overheating of refrigerators and freezers; to protect against corrosion and condensation on the surface

Liquid thermal insulation TC Ceramic HB (Thermal Coat)

Liquid thermal insulation TC Ceramic HB (Thermal Coat) is used to create a thermal insulation coating on any surface. It can be applied to brick, glass, plastic, concrete and other materials. The service life of such a coating is 10 years outside and 25 years inside the building!

Application technology

The application of heat-insulating paint should be carried out in accordance with the instructions; for application, you can use the most common rollers, brushes, and airless sprayers. The thickness of one layer should not be more than 0.5 mm.

A simple method of applying liquid thermal insulation allows you to save time and money during its installation.
The resulting layer of thermal insulation is lightweight, which makes it possible to reduce the weight of the entire structure, and therefore save on building materials.

A thin layer of insulation measured in millimeters allows for savings usable space indoors.

Significant fuel savings during the operation of an insulated room are achieved by reducing heat loss, and the cost of air conditioning in the warm season is also reduced.

The cost of Corundum thermal insulation is consistent with its quality; this is one of the most important factors in the growing popularity of the material and the possibility of its use for thermal insulation works in industrial and private housing construction.

Application of insulation

Having studied the description of the paintable compositions, you can already roughly imagine where they will work most effectively. Corundum insulation is used in somewhat non-standard conditions - where other materials do not give the desired result:

Insulation of heating, water supply, air conditioning and industrial transport systems.

Branched pipes, adapters, tie-ins and fittings - all this also requires the use of insulation. Liquid ceramics creates a continuous, tear-free layer on any complex surfaces. It is much easier to paint pipes than to try to squeeze and secure rolls of glass wool into a confined space, risking leaving “cold bridges”.

Tanks containing flammable or unstable media.

Ultra-thin liquid thermal and waterproofing Corundum not only maintains the temperature inside the containers, but also reflects external IR radiation, protecting the contents from dangerous heat. By the way, the same effect made it possible to find another application for it - coloring. metal roofs, which on a sunny day heat up to +70..+90 °C.

Steel pipes.

Absolute vapor and water resistance, as well as thermal insulation properties ceramic paint prevent not only steel elements from getting wet, but also the appearance of condensation on their surface. We mentioned this at the beginning of our review. Thus, Corundum plays the role of an anti-corrosion coating, ensuring a long service life of metal structures, as well as reducing the costs of their maintenance and repair.

Thermal insulation of external and internal walls of buildings.

For example, protection of loggias and balconies from freezing is carried out from the inside. But mineral wool and polystyrene “steal” a few centimeters on each side of the room. The use of Corundum compositions allows you to achieve the desired effect by simply painting the walls with insulation and thereby preserving the usable area. In addition, liquid ceramics, according to reviews from residents of panel houses, helps to cope with fungus that constantly appears on the damp surface of concrete. And on the facades it serves as a separator of different temperature environments and a reflector of sunlight in summer.

We paint and insulate the insulation

Safety precautions when working with CORUND.

4.1 Personal protection.

Under normal conditions the product is safe. If the room is well ventilated or work is carried out outdoors, respirators are not required. In a room without ventilation, use standard respirators. Use chemical safety goggles to protect your eyes. There must be access to running water to wash the eyes. To protect the skin, use chemical gloves and protective clothing. Wash protective clothing before reuse.

4.2 Critical situations.

If the product gets into your eyes, immediately rinse your eyes with running water for 15 minutes.

If irritation persists, consult a doctor. In case of contact with skin, wash with soap and water. Wash contaminated clothing before reuse. If inhaled, move to fresh air. The product in liquid form is not flammable. In case of fire of structures or structures on which the coating has been applied, use water, foam, dry chemicals and carbon dioxide when extinguishing. In case of product spillage, use any absorbent material such as sand, soil, etc.

4.3 Shelf life.

Guarantee period storage – 12 months.

Types of paint Corundum

Ultra-thin thermal insulation Corundum comes in several types. These modifications differ from each other in properties and some features:

Corundum Classic. This substance is highly effective and is excellent if you need to insulate walls inside and outside, facades, roofs, concrete screeds, pipes (both warm and cold), window slopes, etc. Corundum Classic is also suitable if you need to properly process existing air conditioning systems and steam lines. In addition, Corundum Classic prevents condensation from forming on the surface, and such a layer reduces heat loss.
Anticorrosive This insulation is unique due to the fact that when applied to metal surfaces it prevents corrosion. The uniqueness of this product also lies in the fact that it can be applied to an already rusty layer. It only needs to be removed by rubbing thoroughly. This substance prevents further corrosion processes. In addition, the material also has good thermal insulation properties.
Corundum Winter. It is allowed to work with such a product in slight frost, that is, even if the air temperature is minus 10°C. It will not freeze or undergo polymerization due to low temperatures. For conventional ceramic-type heat insulators, the maximum temperature is only +5°C. Corundum Winter contains acrylic-type polymers and foam glass microgranules that are dispersed in them. Thermal paint Corundum additionally includes pigments, rheological components, inhibitors and a fire retardant, which is important to consider when choosing.
Corundum Facade. This is another paint modification. It was developed specifically to be applied to concrete surfaces. The use of such material is associated with heat-reflecting properties. It is necessary to apply paint in a large layer to speed up the process. In addition, this product is resistant to environmental factors and has good vapor permeability. Excellent for facades and as a decorative layer.

Another option is edel facade panels. They are perfect for those people who want to use finishing materials from famous manufacturer Edel. There are several varieties of such panels (about 3-4 can easily be combined with each other). Edel corundum is one of the types of such facade panels, which are made with a texture like finishing stone. Reviews of this material are positive.

Application of liquid insulation Corundum

Apply like paint - acts as a thermal barrier.

Thermal insulation paint Corundum can be applied with a brush, roller, or conventional spray gun. Sprayers allow you to achieve higher quality of application and reduce material consumption. The average thickness of the layer applied at a time is 0.38 mm. After application, a dense film is formed on the surface within 1/3 hour, impermeable to moisture. Complete chemical drying of the applied layer of thermal insulation takes at least 24 hours. Only after this is it allowed to apply a second layer. If you work with a roller, it average consumption equal to 0.5 l/m. sq.

Modifications of "Corundum",

"Classic";
"Anticor";
"Winter";
"Facade".

The first option is the most universal version, which is used for both external (facade, roofing) and internal work (thermal insulation of various pipelines, floors, window slopes). The second material can be applied directly to the corroded surface. Before work, it is enough to remove loose loose rust.

Any modification in which Corundum insulation is offered (reviews from professional builders confirm this) has additional properties, allowing to provide reliable protection metal surfaces from corrosion.

The performance characteristics correspond to the basic version of Corundum. Using the material to insulate finished structures and laid pipelines can significantly reduce labor costs. No special preparation of the treated surfaces is required. Saving material and money, without compromising the quality of the work performed, is achieved due to the fact that “Anticor” is applied only as the first layer, and then “Classic” is used.

The “Winter” brand can be applied at outdoor temperatures down to (-10) degrees. This is one of the most latest developments manufacturer. The composition of the material includes dispersed multi-composite acrylic polymers, as well as a number of additives.

The “Facade” version was created specifically for concrete surfaces, as well as objects built from slag concrete and foam concrete, which allows us to talk about the material as ideal professional insulation in construction. The optimal vapor permeability values of this material are comparable to similar values inherent in high-quality paint for facades. Material "Corundum" in any of its modifications is today best choice to provide high-quality thermal insulation at minimal cost.

Is this really so, we need to look into it in detail?

First of all, it’s worth starting with the correct definition: corundum is not insulation, but a thermal insulator!

The difference is that the first name denotes a material that is intended for some noticeable insulation of the room. That is, in this case, the temperature inside should improve by at least a few degrees.

But the second concept should be interpreted in the literal sense of the word: an insulator is isolation. In essence, this means that it will not become significantly warmer, but it is also unlikely to become colder. But at least there is a chance to get rid of condensation, fungus or gradual “wetting” of the walls, for example.

Moreover, in the case of insulation (or rather insulator) KKrund, it is possible to eliminate such problems quite cheaply!

Therefore, in principle, it is possible to pay attention to this decision. The main thing is to understand well technical specifications material and get acquainted with the features of application

This will be discussed below.

Advantages

Among the positive characteristics of the new generation of thermal insulation material, it should be emphasized:

amazing lightness, excellent strength,
plasticity, good adhesion to wood, metal surfaces, brick, plastic and concrete,
environmental friendliness - even when heated to high temperatures, the coating is not prone to releasing toxic substances,
the ability to protect surfaces from the effects of ultraviolet rays and corrosion.

The thickness of the coating layer is approximately 0.5 mm. The application of the thermal insulation layer is carried out using technologies similar to the application of conventional paint and varnish materials, there is no difficulty in applying Corundum to objects that have complex configuration and hard-to-reach areas, which ultimately leads to a significant reduction in heat loss in heating networks. The thermal insulation layer does not create additional problems if necessary repair work or maintenance.

The thermal conductivity coefficient of the material is 0.0012 W/m*K, much lower than that of other modern materials used in heat supply systems. The guaranteed service life of the coating is 10 years, and the quality indicators remain virtually unchanged throughout this period, even under operating conditions in moderately cold climatic zones.

Whereas the use of a layer of mineral wool as insulation can last a maximum of 5-6 years, while changes in the initial configuration of the insulation layer and a gradual loss of its properties are observed (due to the tendency of the mineral wool layer to absorb moisture from the environment). Thermal insulation Corundum is not prone to change during operation thermal insulation characteristics, shape, size, decorative qualities.

Tests carried out in which the material was subjected to artificial aging for 30 years, show that its quality characteristics remain virtually unchanged. Those. You can realistically expect that the performance of the coating will be maintained for 30 years when placed indoors and 15 years when placed outside.

Thanks to high quality characteristics Based on the use of high-tech polymer compositions, modern thermal insulation materials are becoming increasingly popular.

Consumers from different countries the world has truly appreciated the possibility of using Corundum thermal insulation in any climatic zone, even with fairly severe temperature conditions. If the application rules are followed and there is no influence of an aggressive environment during operation, the full service life of the material can reach half a century.

Structure of Corundum and its areas of application

This is, in fact, a suspension of ceramics and silicone with vacuum microcavities inside. As a result, an ultra-thin film is obtained on the plane, which resembles a layer of ordinary acrylic paint. The liquid can also be applied using a brush, spray gun or roller.

The characteristics allow this thermal insulator to be used to protect the following structures and elements:

metal hangars and garages;
pipelines with water coolant or just cold water;
water storage tanks;
heating boilers;
steam and gas pipelines;
stone and wooden walls;
slopes.

A very important aspect is the need to purchase certified material, since there are now many counterfeits of Corundum on the market. They pour (literally) anything into a fake liquid, and because of this, of course, no insulating effect can be achieved. Therefore, it is necessary to require documents confirming the authenticity of the insulation.

And by the way, there are different types.

“Classic” - intended for basic finishing of facades, internal walls, slopes and pipelines.
"Facade". The modification is important to use for facades in order to protect walls from fungus, moisture and mold.
"Lotus façade". This type of liquid is best applied as a finishing (covering) layer - that is, on top of “wet” mineral wool facades, for example.
Anticorrosive is used to protect against corrosion, and its technical properties allow it to be applied directly to rust, without any preliminary preparation.
The “Winter” modification contains a composition of acrylic polymers and foam glass microgranules, which allows you to work with the material in winter.
“Fire retardant” is a liquid that, after drying, forms a film that swells when exposed to flame.

These are the modifications of Corundum that exist.

Advantages of thermal insulation Corundum

Liquid heat-saving paint is an innovative composition that differs from all existing coatings. Among the most significant advantages of its use, the following aspects should be highlighted:

The versatility of the substance. It can be applied to any type of surface, including untreated, if this is indicated on the instructions for use. Specialists use thermal paint to treat brick, concrete, metal, plastic surfaces, as well as thermal insulation of equipment and air ducts.
Wear resistance. The applied layer of liquid insulation does not degrade over time. Corundum provides a guaranteed service life of up to 15 years, and with proper care (timely cleaning, high-quality finishing), this figure can be doubled.
Ceramic thermal insulation has good adhesion to any type of material, which provides good protection against moisture and air.
The substance is resistant to alkaline environments.
Liquid thermal insulation provides anti-corrosion protection and minimizes heat loss.
Dry coating with thermal paint reliably protects the treated surface from deformation due to temperature changes, atmospheric influences and moisture formation.
Ceramic thermal insulation is practical and easy to apply to surfaces of complex geometric shapes.
The material is ultra-light, so there is no additional load on the structure. Due to this property, thermal paint is often used when treating roofs.
The substance is quite convenient to repair, because... In case of minor damage, the old layer can be easily removed and replaced with a new one.
Thermal paint reflects up to 80% of the energy of ultraviolet rays.
In addition, liquid insulation is fire resistant. When heated to +260°C, the applied layer is charred, and when it reaches +600°C, the thermal paint begins to decompose, releasing carbon and nitrogen oxide, which prevents the rapid spread of flame.

For information

Liquid thermal insulation Corundum is a mixture based on an acrylic binder and ceramic microspheres, which have thin walls and contain rarefied air inside.

Microspheres have sizes up to 0.5 mm. In addition, it contains various additives, so if Corundum is chosen, the facade will be processed very efficiently, since such additives enhance certain qualities of the product. The composition is completely balanced, so the material is elastic, light and stretchable. In addition, the Corundum coating has good adhesion.

The consistency of the substance resembles simple paint. This is a whitish suspension. The material not only has thermal insulation properties, but is also able to protect metal parts from corrosion.

In addition, Corundum is a thermal insulation that has many other advantages:

Keeps warm well. It has been established that 1 mm of such paint is comparable in its ability to conserve heat with 5 cm of roll-type insulation (for example, mineral wool). The reviews are very good.
It is easy to apply the substance to surfaces. The paint must be applied ordinary tools. You can use a spray gun, roller, or brush. The product does not emit harmful compounds, so respiratory protection is not required.
If Corundum is chosen, the facade will be protected from various damages due to the influence of aggressive environmental factors. For example, metal will not rust. Wood does not dry out or rot. The brick, concrete layer and plaster do not crumble and cracks do not appear on them.
If Corundum is applied, the facade will not be destroyed due to the influence of rodents, insects, bacteria and other pests. The surface does not rot. Mold does not form either.
The insulation layer is lightweight. If Corundum is chosen, the facade will not have additional load, as if other insulation materials were used, for which it is necessary to install additional special retaining structures. Due to the light weight of the layer, Corundum can be applied even to fragile surfaces.
There are no seams. Thanks to this, there will be no cold spots. The thermal insulation layer will be seamless, so the cold will definitely not be able to penetrate into the room.
Durability. It is enough to apply the product only once, and you will not need to replace such a layer for a long time.
The use of the material is also associated with its environmental friendliness. Over a long period of operation, such a layer does not emit harmful components. The product can even be used in homes where people who are prone to allergies live.
Neither the area of the room nor its geometry is affected, which is taken into account when using bulky structures. Corundum will not affect the dimensions and shape of the building.
Can be used as finishing material. Special components from the group of pigments are added to this paint, so it is also used as a decorative coating.

But it must be taken into account that such a heat-insulating layer also has its drawbacks. First of all, this concerns the high cost. The material appeared on the construction products market not so long ago, so the price is still quite high. However, this drawback is offset by the fact that thermal paint retains heat well and the layer will last quite a long time. You also need to take into account that the material, as reviews indicate, hardens very quickly, so you will have to apply it quickly.

An example of an estimate when using corundum thermal insulation

Main types of thermal insulation

The assortment at construction markets and in specialized stores is presented in several versions. Overview of the line of thermal insulating polymer coatings Corundum consists of the following materials:

1. Classic - a liquid substance ideal for roofing and facade works. It is also successfully used for interior decoration. We are talking about insulating the walls of residential premises and general purpose buildings. Corundum Classic is also highly effective in thermal insulation of cold and hot water supply pipelines, concrete and self-leveling floors, and window slopes.

2. Anticorrosive agent can be applied directly to a rust-covered surface. It has high adhesion to metal or concrete, as it is able to create a reliable protective layer. It is advisable to buy Corundum Anticor only for applying the first base layer. For the rest, it is allowed to use classical type thermal insulation.

3. Winter - this type was created specifically for work carried out in the cold season. It can be applied to any surface, even metal, at temperatures down to -10°C. This thermal insulation can be called the “thermal mirror effect”. It significantly reduces heat loss and reflects heated air flows.

4. The facade is suitable for processing concrete surfaces, as well as buildings built from foam or cinder blocks. It is applied in a thick layer, which can significantly reduce labor costs when processing walls. large area. Ultra-thin thermal insulation Corundum Facade is ideal for finishing.

Advantages and disadvantages

Insulation has a number of undeniable advantages:

Relatively low cost. The price of the heat insulator is affordable, and the quality is high.
Reliability and durability.
Significant reduction in heat loss and high heat transfer.
Versatility - the ultra-thin material has a homogeneous, albeit multi-component, composition and can be applied to almost any surface.
Easy to use.
Resistant to environmental influences and ultraviolet radiation.
High energy efficiency.

There are practically no disadvantages. The only thing that should be noted is the absence of long-term tests confirming that all technical characteristics declared by the manufacturer correspond to reality.

Method of use

The surface should be cleaned of dirt and degreased. According to the instructions, Corundum is applied in layers. To do this, you can use a brush, roller or spray. Remember that the thickness of one layer should not exceed 0.3-0.5 mm. The complete drying period is 24 hours. In extreme cases, it can be reduced to 18. Only after this time can the next layer be applied.

Cost in Moscow

Technical characteristics of liquid ceramic thermal insulation Corundum

Thermal conductivity. In numerical value, this indicator is equal to 0.0012 W/(m*C). This is significantly lower than many traditional thermal insulators such as polystyrene foam or mineral wool.
Moisture resistance. The material does not allow moisture to pass through and is not destroyed under its influence. Even saline solutions have no effect on Corundum.
Vapor permeability. Thermal paint does not create an airtight film on surfaces. It allows air exchange to occur, maintaining an optimal microclimate in the room.
Fire resistance. The material does not support combustion. When the temperature reaches 800 degrees, Corundum begins to decompose, releasing carbon and nitrogen monoxide. And at a temperature of +260 degrees, the thermal insulation becomes charred. According to the norms fire safety, the material belongs to class G1 (non-flammable) and B1 (non-flammable).
Adhesion. In terms of tear-off force, this indicator may vary depending on the type of surface on which Corundum is applied. So, for concrete this coefficient is 1.28 MPa, for steel - 1.2 MPa, for brick - 2.0 MPa.
Operating temperature range. Corundum has a fairly large range and ranges from -60 to +260 degrees.
UV resistance. The material does not deteriorate under the influence of sunlight. Therefore, you can use it even without a protective coating.
Biological resistance. Mold, fungi, and rot do not form on surfaces treated with Corundum. Also, the material is not used as food by insects or rodents.
Environmental friendliness. Liquid ceramic thermal insulation does not emit any toxic compounds into the atmosphere even when heated. You can also work with it without using special personal protective equipment.
Lifetime. This is a durable coating that does not lose its quality for at least 10 years. It does not crack and does not collapse.

How good is Corundum as a heat insulator?

As practice shows, condensation on the surface and excess humidity really disappear. In addition, there is a very real chance to completely eliminate mold and rotting of walls, for example. However, if you do it in a good way, and not “for show,” then one layer will not be enough - it is better to apply at least three.

With this approach, the temperature in the room should rise by one and a half degrees. It turns out that some more significant, noticeable improvements can only appear when many layers are applied, but this is no longer practical from a purely financial perspective. At significant expense, it is already easier to make a facade from mineral wool.

This concludes the review of the insulation (or rather thermal insulator) “Corundum” and now, probably, it is easier to draw objective conclusions and make a decision to purchase it.

Customers' opinions

“I live in a private house made of foam blocks, and I’m faced with the problem of freezing in the bathroom and hallway, despite wearing a coat of insulating plaster. I didn’t want to spoil the outer covering and have to do it all over again; on the advice of a friend, I decided to paint the outside walls with liquid thermal insulation, choosing the Korund Facade brand. I applied it myself using a sprayer in 2 layers and finished it in two days. The consumption for a one-story house of 70 m2 was 200 liters. Over the past winter, I noticed gas savings; the walls did not freeze.”

Ilya Varentsov, Moscow.

“I used Corundum Anticor to paint the cold water supply riser in the apartment. Before this, the pipe was constantly wet and rusting; anti-corrosion primers did not help. Before applying thermal insulation, I lightly cleaned the surface of rust and old paint. Now it is absolutely dry, condensation does not accumulate.”

Andrey Panin, Krasnodar.

“I built a house from scratch, after installing the heating system, I painted the pipes laid at floor level with anti-corrosion heat-insulating material Corundum. I am very pleased with the result: there is no rust, the coating does not peel off or crack. In addition, the temperature of the coolant in areas remote from the boiler almost does not decrease.”

Alexander Zinoviev, Ekaterinburg.

“We decided to buy Corundum Classic to protect the corner children’s room in the apartment from the cold. After reading reviews from other consumers, we realized that one layer would be enough; the composition was applied with a roller. To save money, we painted two walls adjacent to the street, which took 25 liters. In winter, the room was not only warm, but also dry. The noted disadvantage of Corundum: only this color is available.”

Yulia Belozertseva, St. Petersburg.

In addition to those already mentioned useful characteristics, Corundum is valued for its permanent shape and stability. Polymer additives provide a high level of adhesion to any building materials: concrete, metal, wood, brick. The unique structure promotes uniform distribution of the insulating suspension over the surface, and ceramic microspheres within the layer.

According to the manufacturers, 1 mm of polymer thermal insulation is equivalent to 50 mm of foam plastic, rolled products, or 1.5 bricks; customer reviews confirm this information, but in general the material is considered still new and completely untested. The disadvantage is the high price (on average from 370 rubles per 1 liter). Corundum is inferior to other types of insulation in sound absorption; a thin layer does not interfere with noise and vibration.

Summary

Liquid composite thermal insulation is suitable for treating complex and hard-to-reach surfaces, ideal in confined spaces. It guarantees free access to the required area without stopping production process, therefore in demand among housing and communal services and in industrial facilities. The characteristics of Corundum do not limit the scope and conditions of use, but it is not suitable as sound insulation.

Can be used as a complement to other options (plaster, expanded polystyrene). To work with metal, it is worth buying the Korund Anticor brand, for insulation external walls- combine Facade and Facade-lotus (the latter type is also recommended as a reinforcing coating). To achieve maximum effect, strict compliance with the instructions and application of a layer of the required thickness (taking into account the characteristics of the building material and the density of the walls) is required.

Ceramic insulation technology

It is necessary to apply ultra-thin thermal insulation Corundum to a previously prepared surface, regardless of the modification of the composition. The basic rules that should be followed before starting paint insulation include the following:

If ceramic insulation is intended for wall treatment, the working surface should be cleaned of dust and dirt, and existing gaps and chips should be expanded and filled with cement mortar.
Before painting thermal insulation on concrete slabs, they should be cleared of “cement laitance”.
It is also necessary to treat the wall with an abrasive wheel, sandblasting machine or a stiff metal brush.
If you plan to treat a metal surface, it must be dust-free and degreased (substances recommended by the manufacturer - Solv-Ur, Solvent). To paint objects made of non-ferrous metal, it is necessary to remove the gloss and apply primer VL-02 or VL-023.
It is also worth considering that it is necessary to dilute ceramic thermal paint immediately before applying it to the wall.

Important! It is recommended to mix liquid thermal paint Corundum manually. However, for work with large volumes, it is permissible to use a construction mixer, the rotation speed of which should not exceed 200 rpm

Otherwise, there is a risk of destruction of the hollow ceramic granules, which will negatively affect the thermal insulation properties of the composition. As a rule, manual mixing takes 10-15 minutes. When working construction mixer this figure will be 3-7 minutes.

It is also worth considering that in some modifications of the composition it is necessary to add water before starting work, so you need to carefully study the manufacturer’s instructions. The volume of liquid depends on the purpose of thermal insulation; in any case, the required proportions are indicated on the packaging of the composition.

The technique of applying ultra-thin thermal insulation Corundum is carried out in three ways:

using air spray devices;
airless spray method;
manually - using a roller or brush.

The manufacturer recommends applying the composition in three layers, and the consumption should be 1 m/m2. When working on thermal insulation, this composition does not require additional ventilation in the room, nor the use of special personal protective equipment.

To guarantee the effectiveness of the result, it is important to strictly follow the manufacturer’s instructions and fully adhere to the recommendations indicated on the packaging.

Specifications

Corundum paint has technical characteristics that allow it to be used for structures with different purposes and configurations. Even if the layer is minimal, the product still remains a good insulator.

The following main characteristics of Corundum paint are distinguished:

Thermal conductivity. The indicator is approximately 0.0012 W/(m*S). This parameter is noticeably lower than that of other materials that are used as thermal insulators (for example, this applies to mineral wool, foam plastic, etc.).
Moisture resistance. The substance will not allow water to pass through. In addition, the layer is not destroyed by moisture. Even solutions with a high salt content will not have an effect.
Vapor permeability. The paint does not form an airtight film, so it will not interfere with air exchange in the room. Thanks to this, an optimal microclimate is maintained inside.
Fire resistance. The material is not subject to combustion. When the temperature rises to 800°C, the paint simply begins the process of decomposition. As a result, nitrogen and carbon oxides are released. If the temperature is 260°C, then the heat-insulating layer simply becomes charred. In terms of fire safety, such material belongs to categories G1 and B1, that is, it does not burn or ignite.
Adhesive properties. The indicator may differ depending on the surface itself on which Corundum insulation is to be applied. For example, if a concrete layer is used, then the index is 1.28 MPa. For steel it is 1.2, and for brick - 2.
Operating temperatures include a range from -60°C to 260°C.
Resistance to ultraviolet radiation. The material will not deteriorate when exposed to direct sunlight. It can be used even without a special protective layer.
Biological resistance, that is, the material is resistant to the action of fungi, mold, and bacteria. It won't rot. In addition, rodents and insects will not be able to eat such coating.
Environmental friendliness. This ceramic type paint does not emit toxic substances, even if it is heated. In addition, when applying it, you do not need to use special means personal protection.
Operating time. This coating is durable. It can last at least 10 years. During this time it will not collapse or become covered with cracks.

Basic properties of corundum thermal insulation

Thermal insulation corundum has a microporous structure that reflects about 85% of radiation. A significant reduction in heat loss occurs due to the low thermal conductivity coefficient. What other properties can this insulation boast?

The temperature regime in which thermal insulation retains its effectiveness and properties is from -60 to +250 degrees Celsius.
The manufacturer promises to preserve the properties of the material for 15 years.
For greater safety, the Corundum heat insulator is also available in a frost-resistant version. Storage of such material is allowed even at temperatures of -30 degrees. True, in such unfavorable conditions, thermal insulation can last no more than 1 month. Allow 5 cycles of freezing the material before using it.

Heat insulator Corundum is available in a whole range of modifications

The Corundum Classic material is a universal heat insulator that is used to insulate the external and internal surfaces of residential, industrial, office buildings and structures, pipeline systems, as well as refrigerators, tanks and other industrial containers. The heat insulator is available in plastic buckets, which can have a volume of 5,10 or 20 liters. Cost - from 300 rubles per liter. When purchasing in bulk, you can get a discount (approximately 10%).
Insulator Corundum Facade is specially designed for thermal insulation of facades made of all kinds of materials. This insulation can be applied directly to the outer wall of a building with a layer thickness of 1 mm in one application. This modification has increased vapor permeability, due to which it is possible to natural ventilation building. Thermal insulation Corundum Facade has proven itself in eliminating fungi, mold, freezing of walls or structures. The material is produced in plastic buckets with a capacity of 5, 10 or 20 liters. Price – from 330 rubles per 1 liter, with wholesale purchases you can get an additional 5-15% discount.
Thermal insulation Corund Anticor is unique in that it can be applied to a rusty surface. It is enough to remove the outer layer of rust, which is loose and easy to clean with a wire brush. After this, insulation can be applied. Corundum Anticor not only preserves the surface and has anti-corrosion resistance, it effectively prevents the spread of oxidation deeper and wider than the surface. This type of material is successfully used for insulating pipelines and metal structures, as well as as a base layer for the subsequent application of other products of the manufacturer, for example, Corundum Classic. The insulator is available in plastic buckets with a volume of 10 or 20 liters. The cost of 1 liter of Antikor is from 410 rubles. When purchasing in bulk, you can count on a discount of about 10%.
Thermal insulation Korund Winter is perfect for those cases when the work on thermal insulation of the facade occurs in the winter season. The coating is intended for objects requiring high-quality thermal insulation, including those susceptible to corrosion and prone to condensation. We remind you that most known thermal insulation materials can be worked at temperatures not lower than +5 degrees. Corundum Winter can even be stored at low temperatures (up to + 30). The insulation is supplied in a plastic bucket with a volume of 20 liters. 1 liter of liquid winter modification insulator costs from 420 rubles.
A material under the working title Corundum Fire Protection is under development. It is intended to increase the fire resistance limit of residential and industrial buildings and structures. When exposed to high temperatures, the coating provides fire resistance of 1 hour with a dry layer thickness of 1.5 mm. The coating system consists of soil, fire retardant material and a finishing coating with fire-resistant properties.
Thermal insulation Corundum can be used comprehensively, in a combination of several materials. For example, to insulate a metal surface, a layer 2.5 mm thick is required. In order to achieve this indicator as efficiently as possible, you can use the Corund Anticor modification for the primer, and then apply two layers of Corundum Facade. Thus, the required insulation thickness of 2.5 mm will be obtained, while an anti-corrosion, moisture-resistant and heat-insulating surface coating will be provided.

Liquid insulation - what is it?

It is believed that the basis for the manufacture of this type of material was the development for the space industry. This composition was developed for the external coating of modules and vehicles intended for flights in low-Earth orbit. We don’t know for sure whether this is true or just another beautiful legend, but the special properties of this material are obvious. What is liquid thermal insulation made of?

The material is based on hermetically sealed ceramic capsules filled with inert gas. Acrylic polymers were used as the connecting suspension. Thus, about 85% of the total mass of the material is ceramic microspheres, and the remaining 15% is the connecting mixture.
Such an unusual composition makes liquid insulation a truly unique material. Suffice it to say that just 1 layer of such insulation will completely replace a 50 mm layer basalt wool. The liquid insulator has a thermal conductivity coefficient of 0.01 W, which is currently considered the lowest. The material does not absorb moisture at all. After drying, the insulation forms an even, homogeneous layer, insensitive to rain, frost, ultraviolet radiation, high temperatures and mechanical stress. It does not evaporate moisture and does not emit compounds harmful to humans. In addition, it does not need to be covered. finishing, it has a high degree of aesthetic appeal.
As for application, it does not require any special skills or equipment. It is enough to arm yourself with a brush, spatula or roller. The insulation is diluted with water to the desired consistency and then applied to the surface to be insulated. The number of layers for different walls can vary from 3 to 6. As you can see, in terms of this indicator, this type of insulation has significant advantages.
