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 concrete house with thermal insulation from Korund Facade. 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.”

Fedor Vorobyov, Ivanovo.

PRICE for 1 liter - 330 rub. FOR WHOLESALERS % DISCOUNTS

With all its positive qualities, Corundum thermal insulation is also affordable. You can choose a convenient packaging and save on installation: the paint is applied with a spray or brush. Consumers who have used Corundum clearly distinguish this thermal paint from similar ones. Even without special equipment, but simply by 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!

"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 resistant;
  • "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 interior 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 it forms an ultra-thin protective layer(from 0.5 mm), 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). Facilities personal protection are not 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 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:

  1. 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.
  2. 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.
  3. Allow the surface to dry completely before applying paint. The first layer should be minimal in thickness, since it is a primer.
  4. 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.
  5. It is recommended to do no more than 3 layers of paint for optimal results.
  6. 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 off the top layer of 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 of minimum thickness, as it is considered a primer.
  • If you use a spray gun or roller to apply Corundum, then the joints and hard to reach places In any case, you will have to apply it 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 surface to be insulated must be cleaned of dirt, rust, dust, old paint, and crumbling elements must be removed.

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. Cleaning up metal surface remove 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 removal of preservatives. 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 savings; 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 of 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 you to save useful 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 work in industrial and private residential 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 compounds 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

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.

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. To wash the eyes, there must be access to running water. 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 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.

4.3 Shelf life.

Guaranteed shelf life – 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:

  1. 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.
  2. 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.
  3. 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.
  4. 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 that of a 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 get more high quality 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",

  1. "Classic";
  2. "Anticor";
  3. "Winter";
  4. "Facade".

The first option is the most universal version, which is used for both external (facade, roofing) and interior works(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 of 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 latest developments from the 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 an ideal option for 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 ensure 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, it is not difficult to apply Corundum to objects with complex configurations 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 using a layer as insulation mineral wool 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 around the world have appreciated the possibility of using Corundum thermal insulation in any climate 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.

  1. “Classic” - intended for basic finishing of facades, internal walls, slopes and pipelines.
  2. "Facade". The modification is relevant to use for facades in order to protect walls from fungus, moisture and mold.
  3. "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.
  4. Anticorrosive is used to protect against corrosion, and its technical properties allow it to be applied directly to rust, without any prior preparation.
  5. The “Winter” modification contains a composition of acrylic polymers and foam glass microgranules, which allows you to work with the material in winter.
  6. “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:

  1. 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.
  2. Wear resistance. Applied layer 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.
  3. Ceramic thermal insulation has good adhesion to any type of material, which provides good protection against moisture and air.
  4. The substance is resistant to alkaline environments.
  5. Liquid thermal insulation provides anti-corrosion protection and minimizes heat loss.
  6. Dry coating with thermal paint reliably protects the treated surface from deformation due to temperature changes, atmospheric influences and moisture formation.
  7. Ceramic thermal insulation is practical and easy to apply to surfaces of complex geometric shapes.
  8. 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.
  9. 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.
  10. Thermal paint reflects up to 80% of the energy of ultraviolet rays.
  11. 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:

  1. Keeps heat 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. Durability. It is enough to apply the product only once, and for a long time there is no need to replace such a layer.
  8. 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.
  9. 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.
  10. Can be used as a 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 insulation 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 buildings general purpose. 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, the use of thermal insulation is allowed classic type.

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.
  • Environmental resistance 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.

Technical characteristics of liquid ceramic thermal insulation Corundum

  1. 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.
  2. 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.
  3. 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.
  4. 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).
  5. 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.
  6. Operating temperature range. Corundum has a fairly large range and ranges from -60 to +260 degrees.
  7. UV resistance. The material does not deteriorate under the influence of sunlight. Therefore, you can use it even without a protective coating.
  8. 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.
  9. 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 means personal protection.
  10. 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 high level 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 the production process, therefore it is in demand among housing and communal services and at industrial facilities. The characteristics of Corundum do not limit the scope and conditions of use, but it is unsuitable as sound insulation.

Can be used as a complement to other options (plaster, expanded polystyrene). To work with metal, you should buy the Korund Antikor brand; to insulate external walls, combine Facade and Facade-Lotus ( last view also recommended as a strengthening coating). For achievement maximum effect it is necessary to strictly follow the instructions and apply a layer of the required thickness (taking into account the characteristics of the building material and the density of the walls).

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:

  1. If ceramic insulation is intended for wall treatment, work surface should be cleaned of dust and dirt, and existing gaps and chips should be expanded and filled with cement mortar.
  2. Before paint thermal insulation on concrete slabs, they should be cleared of “cement laitance”.
  3. It is also necessary to treat the wall with an abrasive wheel, sandblasting machine or a stiff metal brush.
  4. If you plan to treat a metal surface, it must be dust-free and degreased (substances recommended by the manufacturer are 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.
  5. 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 with a 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:

  1. 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.).
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. Operating temperatures include a range from -60°C to 260°C.
  7. Resistance to ultraviolet radiation. The material will not deteriorate when exposed to direct sunlight. It can be used even without a special protective layer.
  8. 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.
  9. 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 personal protective equipment.
  10. 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.

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 it made of? liquid thermal insulation?

  1. 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.
  2. Such an unusual composition makes liquid insulation truly a unique material. Suffice it to say that just 1 layer of such insulation will completely replace a 50 mm layer of basalt wool. The liquid insulator has a thermal conductivity coefficient of 0.01 W, which, this moment, is considered the lowest indicator. 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 with finishing; it has a high degree of aesthetic appeal.
  3. 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. 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.

What is Corundum insulation, how is it produced, what types exist, technical characteristics of the material, advantages and disadvantages, features of do-it-yourself application.

Description and features of Corundum production


Liquid heat insulator Corundum is a mixture of acrylic binder and ceramic microspheres with thin walls that contain rarefied air. Acrylic binder is made using fixatives and catalysts.

Microspheres have a size in the range of 0.01-0.5 millimeters. Also, various additives are additionally introduced into the product, which are designed to enhance its certain qualities. This balanced composition gives the material lightness, elasticity, flexibility and stretchability. In addition, Corundum has excellent adhesive ability.

The consistency of liquid ceramic heat insulator is similar to ordinary paint. Essentially it is a suspension white, which after polymerization forms an elastic and durable polymer coating.

Unlike conventional thermal insulation materials, Corundum not only protects a building or any other structure well from heat loss, but also prevents metal surfaces from rusting.

Initially, such ceramic heat-protective coatings were created by order of NASA for use on spacecraft. After some time, it was possible to adapt these compositions to “earthly” needs. Corundum is the trade name of a product developed by Russian scientists. This heat insulator has all the necessary certificates confirming its quality.

Main varieties of Corundum


The product has several industrial modifications:
  • Corundum Classic. This is a highly effective substance for insulating facades, roofs, walls (inside and outside), window slopes, concrete screeds, hot and cold pipes, steam pipelines, and air conditioning systems. Thermal paint completely eliminates the possibility of condensation forming on surfaces and also significantly reduces heat loss.
  • Corundum Anticorrosive. This insulation is unique in that it can be applied directly to rusty metal. It is recommended only to remove the layer of loose rust. The product has anti-corrosion properties - it does not “preserve” rust, but prevents its formation. In addition, Antikor is known for its excellent thermal insulation characteristics.
  • Corundum Winter. You can work with this product in temperatures down to -10 degrees. It does not freeze or polymerize when exposed to low temperatures. Note that the permissible minimum rate for applying conventional liquid ceramic heat insulators is +5 degrees. Corundum Winter contains acrylic polymers and foam glass microgranules dispersed in them. In addition, flame retardants, pigments, inhibitors and rheological components are added.
  • Corundum Facade. This thermal insulation is designed specifically for application to concrete surfaces. Has increased heat-reflecting properties. This product can be applied in thick layers, which speeds up the work process. Corundum Facade is also characterized by good vapor permeability and resistance to atmospheric influences. It is allowed to apply decorative facade coatings over liquid thermal insulation Corundum.

Technical characteristics of liquid ceramic thermal insulation Corundum


Thermal insulation material Corundum has technical characteristics that allow it to be used on structures of various configurations and purposes. With a minimum thickness, this product can provide a good level of insulation.

Let's consider the main characteristics of Corundum thermal insulation:

  1. 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.
  2. 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.
  3. 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.
  4. 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 fire safety standards, the material belongs to classes G1 (non-flammable) and B1 (non-flammable).
  5. 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.
  6. Operating temperature range. Corundum has a fairly large range and ranges from -60 to +260 degrees.
  7. UV resistance. The material does not deteriorate under the influence of sunlight. Therefore, you can use it even without a protective coating.
  8. 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.
  9. 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.
  10. 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.

Advantages and disadvantages of Corundum


The heat insulator is capable of completely filling the micropores of the surface being treated. In this case, the concentration of polymerized material is 80%. In addition, coating thermal insulation Corundum has the following advantages:
  • Excellent heat retention. One millimeter of heat-saving paint is comparable in effectiveness to 50 millimeters roll insulation, for example, mineral wool.
  • Easy to apply. Corundum is applied like regular paint using standard tools: brush, roller, spray gun. He doesn't highlight harmful substances, therefore does not require respiratory protection.
  • Protects surfaces from destruction. Metal coated with Corundum will not rust, wood will not rot and dry out under the influence of atmospheric conditions, plaster, brick, concrete will not crumble and become cracked.
  • Does not attract microorganisms, insects, rodents. Surfaces covered with this insulation will not rot or mold.
  • Lightness of the insulating layer. The weight of Corundum insulation is incomparable with traditional roll coating. Such thermal insulation will not exert any load on load-bearing walls and foundation. Therefore, liquid ceramic insulation can be applied even to unstable and fragile structures.
  • No seams or cold bridges. Corundum allows you to create a durable, seamless coating through which the cold cannot penetrate into the room.
  • Environmental friendliness and durability. Throughout its entire service life, the material does not emit any harmful substances. Therefore, it can be safely used to insulate residential buildings, as well as houses where allergy sufferers live.
  • Does not affect the geometry of the room. Unlike bulky traditional thermal insulation, Corundum will not affect the size and shape of the building in any way.
  • Can serve as an independent finishing layer. Pigments can be added to thermal paint, which allows it to be used for wall decoration without additional decorative coatings.
This liquid ceramic insulation also has certain disadvantages. First of all, it is a relatively high price. Corundum appeared on the domestic market not so long ago, so its cost is still quite high. However, this drawback is offset by the fact that thermal paint is characterized long term operation and retains heat perfectly.

Also among the disadvantages is the rapid hardening of the material. Therefore, you need to work with it quickly.

Criteria for choosing Corundum insulation


The rights to the Corundum trademark in Russia belong to NPO Fulleren. The company also has a number of official distributors, for example, TeploTrade LLC, ServiceInvestProekt CJSC, Korund Southern Federal District Trading House LLC and others. Never buy goods from dubious sellers.

The optimal state of Corundum insulation is a white paste-like suspension. Standard packaging is plastic buckets of different sizes. The packaging must indicate the manufacturer's information.

The price of Corundum thermal insulation may vary depending on the type of material and place of sale. On average in Russia the cost of liquid ceramic insulation is as follows:

  1. Corundum Classic - 375 rubles per 1 liter;
  2. Corundum Anticor - 435 rubles per liter;
  3. Corundum Winter - 540 rubles per liter;
  4. Corundum Facade - 400 rubles per 1 liter.

Brief instructions for applying Corundum thermal insulation


To apply thermal paint, you will need standard painter's tools - brushes, roller or spray gun. Using a sprayer you can get best quality application and low consumption of thermal insulation Corundum.

The average thickness of one layer should be about 0.4 mm. Each subsequent layer should be applied only after the previous one has completely dried. When working with a roller or brush, the average material consumption is about 0.5 liters per square meter.

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 off the top layer of 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 of minimum thickness, as 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.
The heat insulator Corundum on surfaces looks aesthetically pleasing, and therefore can be used as a finishing material. If you are planning additional painting or plastering of surfaces, then this can be done over layers of thermal paint.

Watch the video review of Corundum:


Corundum is the latest invention of Russian scientists in the field of thermal insulation. The material is widely used for insulation of buildings for various purposes, pipelines and other objects. This is an environmentally friendly and reliable ceramic liquid thermal insulation.

Thermal insulating liquid material produced by KORUND, based on its physical properties and consistency, is very similar to ordinary white paint that is used to paint standard surfaces. Thermal insulation CORUND has only positive reviews. All this is due to the fact that the material consists of a high-quality acrylic binder component, ultra-thin ceramic microspheres with a composition of rarefied air and a specially developed composition of fixatives and catalysts.

In the production of such materials, special additives are also used that completely eliminate the occurrence of corrosion and fungal accumulations in conditions of high humidity. Thanks to this composition, liquid thermal insulation CORUND (read reviews on our website) is flexible, soft, light and stretchable.

After application, the insulation forms an elastic polymer sheathing with unique properties compared to .

The new generation material has already proven its reliability as a temperature preservation component. In addition, CORUND thermal insulation has technical characteristics favorable for combating corrosion and the appearance of condensation on cold surfaces.

Types of materials CORUND

Thermal insulation products of the KORUND company have several varieties:

  • CORUND ANTIKOR

A universal material applied directly to rusty surfaces. Before application, you just need to walk over the surface with a regular wire brush to remove the dry layer of rust.

The insulation has an additional anti-corrosion property. Thanks to this, the cost of preparing the surfaces to be treated is significantly reduced.

  • CORUND CLASSIC

It is an ultra-thin material with good thermophysical properties. During transportation, the liquid composition of the insulation is practically not divided into fractions.

  • CORUND FACADE

This type of material is applied in layers (thickness from 1 mm), so it subsequently looks like. FACADE heat-insulating paint also has only positive reviews from customers. This ultra-thin liquid heat insulator is used for concrete surfaces.

FACADE paint also received excellent reviews in combination with ANTIKOR paint.

Operating principle and scope of application of CORUND insulation

The essence of thermal insulation materials of the liquid-ceramic structure CORUND lies in the needs of those areas where it is extremely necessary to preserve and conserve heat inside buildings. Thermal insulating paint CORUND (characteristics), the temperature of which implies use in different countries (Russia, Belarus, Ukraine, Kazakhstan, South Korea, Asia and the European Union), has high elasticity.

CORUND materials are widely used in interior walls, roofs, concrete floors, window slopes, cold and hot water pipeline systems, steam pipelines, and cooling systems.

Heat retention indoors largely depends on the thermal insulation parameters of the building itself and the used finishing materials. Reliably insulating a house means reducing heating costs. Today, the construction industry offers many types of insulating materials, which vary in their characteristics and costs. One of the most optimal options is liquid thermal insulation Corundum, which is characterized by durability and excellent thermal insulation properties. Let us consider in more detail the features of the composition, selection criteria and application technique.

The unique composition of thermal insulation is also called heat-reflecting paint, since with a layer thickness of only 1 mm it can have a noticeable energy saving effect. Thanks to this, Corundum thermal insulation is very economical in consumption. The filler consists of microscopic hollow spheres - ceramic, polymer, composite, glass balls, which are filled with rarefied air. Such microparticles can vary not only in composition, but also in the size of microgranules, percentage, homogeneity of components, etc.

Externally ceramic superfine paint practically no different from ordinary paint on acrylic base. Despite the fact that today the construction market offers several varieties of ultra-thin insulating compositions, almost all of them have a similar structure:

  1. The thermal paint is based on a water-acrylic solution. Its properties make it possible to ensure uniform distribution of thermal insulation components over the working surface. In addition, the composition promotes better fixation of liquid ceramics.
  2. The binder also contains various additives that improve the performance parameters of the thermal paint. The most common material additives include natural and artificial rubbers, silicone, etc.

Liquid thermal insulation Corundum: technical characteristics and principle of operation

The temperature range for thermal paint varies from -65°C to +260°C. The main technical characteristics are vapor permeability and hygroscopicity of liquid insulation, which can be applied to almost any type of facade material: concrete, stone, brick, metal, plastic, etc.

This material guarantees the removal of condensation that forms on walls and pipes in the room. The composition of this warm paint includes special fixatives, catalytic substances, anti-corrosion additives, as well as a binder base based on high-strength acrylic. Along with the content of microspheres, this composition is easily applied and distributed over the entire surface, providing good energy saving and thermal insulation.

An important argument for buying liquid thermal insulation Corundum is the safety of the substance. Thanks to the content of natural additives and environmentally friendly components, the treated surface is non-toxic and does not emit any odors. This allows you to use thermal paint to insulate any room. You can create a stable thermal barrier even in children's rooms or homes where there are allergy sufferers.

The thermal insulation properties of the composition can be achieved in several ways:

  1. Through convection, i.e. heat transfer by the thermal paint layer itself. Due to the fact that most of specific gravity Liquid insulation consists of hollow balls; losses due to convection in the composition are completely insignificant.
  2. Thermal conductivity of a material, when heat is transferred from a hotter part of the surface to a colder place. In liquid insulation, only 20% of the binder component has thermal conductivity properties.
  3. Radiation is a phenomenon in which heat transfer occurs through the internal energy of a suspension. In energy-saving paint, microscopic spheres are endowed with the properties of heat reflection and dissipation. Almost 90% of the reflected radiation turns the working surface of the wall into an analogue of a thermos.

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:

  1. 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.
  2. 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.
  3. Ceramic thermal insulation has good adhesion to any type of material, which provides good protection against moisture and air.
  4. The substance is resistant to alkaline environments.
  5. Liquid thermal insulation provides anti-corrosion protection and minimizes heat loss.
  6. Dry coating with thermal paint reliably protects the treated surface from deformation due to temperature changes, atmospheric influences and moisture formation.
  7. Ceramic thermal insulation is practical and easy to apply to surfaces of complex geometric shapes.
  8. 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.
  9. 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.
  10. Thermal paint reflects up to 80% of the energy of ultraviolet rays.
  11. 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.

Disadvantages of ultra-thin thermal paint Corundum

Despite the impressive list of advantages of the material, it is not without some disadvantages. Among them, the following aspects should be highlighted:

  1. High cost of thermal paint.
  2. Since ceramic thermal insulation is a relatively new product on the construction market, there is no time-tested evidence that the material meets its declared characteristics.

Main types of thermal insulation

Liquid ultra-thin thermal insulation is available for sale in specialized construction stores in several versions. The entire line of polymer compositions consists of the following types:

  1. Thermal insulation Corundum Classic is a liquid suspension intended for roofing and facade work. This composition has also found application in interior decoration premises, providing reliable thermal insulation of walls in residential buildings and general purpose buildings. In addition, the classic variety is highly effective for insulating concrete floors, self-leveling coatings, hot and cold water supply communications, as well as insulating window slopes.
  2. Corundum Anticor is a special anti-corrosion composition that can be applied simply to a rust-covered surface, without special treatment. This kind of warm paint is different high performance adhesion to concrete and metal, creating a reliable protective and insulating layer. As a rule, this liquid thermal insulation Corundum is slightly cheaper in price than the classic type and is used to create the first base layer of insulation.
  3. Facade is a type of heat-saving paint intended for treating concrete surfaces, as well as buildings made of slag or foam blocks. The composition is applied in a thicker layer, thereby reducing the labor cost for treating large surfaces. This type Warm paints are usually used for finishing.
  4. Winter – liquid thermal insulation intended for work in the cold season. The principle of energy saving is based on the “thermal mirror effect”, i.e. reflections of flows of heated air masses. This composition is universal and can be applied to almost any surface at ambient temperatures down to -10°C.

General criteria and features of selection

Ceramic thermal insulation is not yet a fairly common type of coating, which is due to the high cost of the product. However, experts claim that this substance has exceptional performance characteristics, the value of which significantly exceeds the cost of acquisition. To choose optimal view liquid thermal insulation, it is important to take into account the following features:

  1. The first thing that affects the final result of ceramic insulation treatment is the density of the composition. High-quality thermal paint is characterized by an indicator of about 0.6 kg per 1 liter of product. Those. The weight of a standard 10 liter bucket should not exceed 7.5 kg.
  2. It is also worth looking at the container with the solution “through the light” to determine the degree of its separation. Good indicator of quality and efficiency thermal insulation properties there will be a dense top layer of substance. As a rule, ceramic spheres have a light fraction that rises to the top. Thus, the thicker the top layer, the higher the thermal insulation properties.
  3. An equally important selection criterion is the structure of the suspension itself. To determine it, you need to rub a couple of drops of heat paint between your fingers. IN quality composition microgranules of ceramic balls are felt, i.e. the substance has roughness.
  4. In addition, it is necessary to take into account the color of the liquid thermal insulation. Corundum is available in white, so the paint is gray or yellow tint- clear evidence of counterfeit products.

Application area

Ultra-thin ceramic insulation Corundum is an innovative material that forms a durable elastic coating that reliably protects the surface from moisture, overheating and corrosion. This composition is used in the temperature range from -65°C to +260°C.

The main areas of application of thermal paint include:

  • housing and communal services facilities (including treatment of pipelines for various purposes, thermal insulation of facades, roofs, windows, walls);
  • transport industry;
  • oil industry;
  • insulation of thermal power structures;
  • construction industry.

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:

  1. 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.
  2. Before painting thermal insulation on concrete slabs, they should be cleaned of “cement laitance”.
  3. It is also necessary to treat the wall with an abrasive wheel, sandblasting machine or a stiff metal brush.
  4. If you plan to treat a metal surface, it must be dust-free and degreased (substances recommended by the manufacturer are 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.
  5. 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 with a 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.

Conclusion

The use of ceramic thermal paint is an innovative approach that has undeniable advantages over traditional methods of thermal insulation of surfaces. The article discusses the main features of liquid thermal insulation Corundum, reviews, selection criteria and methods of applying the composition. The resulting coating layer is lightweight, has excellent performance characteristics and is easy to use.

Features of choosing liquid insulation Corundum. Video:

A material such as liquid thermal insulation corundum is quite well known today. And it is this heat insulator that causes a lot of controversy and doubt, since in advertising they usually say that one millimeter of layer, which is applied like ordinary paint, is equal in properties to 5 cm of mineral wool.

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 the technical parameters of the material and become familiar with the application features. This will be discussed below.

Structure of Corundum and its scope 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.

  1. “Classic” - intended for basic finishing of facades, internal walls, slopes and pipelines.
  2. "Facade". The modification is relevant to use for facades in order to protect walls from fungus, moisture and mold.
  3. "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.
  4. Anticorrosive is used to protect against corrosion, and its technical properties allow it to be applied directly to rust, without any prior preparation.
  5. The “Winter” modification contains a composition of acrylic polymers and foam glass microgranules, which allows you to work with the material in winter.
  6. “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 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 resistant;
  • "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.

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.
