Instructions for applying corundum® classic. Liquid thermal insulation Corundum: characteristics, advantages and disadvantages What is heat paint corundum
In one of the articles we helped you understand the types bulk insulation. Today we will talk about a composite with high thermal insulation properties, called liquid thermal insulation “Corundum”. Without exaggeration, she is the first domestic product created in our country using national technologies using high-quality imported raw materials. This is the best material in its niche in terms of the ratio of the quality of the result and the cost of the material.
Meet liquid thermal insulation Corundum
The consistency is more like mastic.
The mentioned ultra-thin liquid insulation “Corundum” is made on the basis of:
- a binder made on the basis of high quality acrylic with the addition of unique catalysts and various fixatives;
- microspheres made of ceramics with ultra-thin walls that contain rarefied air.
In addition to the main composition, the mentioned thermal insulation “Corundum”, reviews of which are extremely positive, includes special additives. They eliminate the occurrence of corrosion on metal surfaces and the appearance of fungus from excess moisture. This combination made it possible to obtain light and flexible material, with the highest adhesion to almost any surface it coats. If you want to understand what liquid insulation Corundum is, reviews on the Internet and the public press will help you with this.
It is a white suspension, similar to paint, that can be easily applied to surfaces of any shape, be it brick, concrete, plastic or metal.
After complete chemical drying, a very elastic coating is obtained on the treated surface. polymer based. It has the highest properties heat insulator and allows you to create effective protection against corrosion. Isolation is applied when executing roofing works and arrangement of building foundations, as well as life support systems. We have already told you how to insulate the foundation of a house yourself. The use of Corundum makes it possible to almost completely eliminate the occurrence of condensation on supply pipelines cold water. The material significantly reduces heat losses heating systems.
At hidden installation communications, fastenings for heating pipes to the wall must be installed in order to fix the circuit.
Even if it is not possible to wall up communications, you can decorate them by creating decorative heating pipes. They can become the highlight of your interior.
Characteristics of the material "Corundum"
Multi-colored dyes can be added to the white composition.
Thermal insulation Corundum, the technical characteristics of which are given below, is in demand at any facility. Before starting work, the specified insulation can, if necessary, be diluted with ordinary water.
The film of this thermal insulation, which is only 1 mm thick, begins to decompose if the temperature exceeds 840 degrees. The process takes place with the release of nitrogen and CO, which allows to slow down the processes of combustion and smoke. Thermal insulation capabilities of ultra-thin liquid insulation exceed the parameters of sheet and roll insulation, the thickness of which can reach 5–7 cm, as well as brickwork made in one row.
Corundum insulation paint can be applied almost anywhere. The requirements for the surface before applying the material are minimal:
- it must first be degreased;
- remove dirt;
- clean from dust and, to a first approximation, from rust.
Temperature work surface should be between 7-150 degrees Celsius. The temperature range declared by the manufacturer for operation is - 60/+ 260 degrees. Guarantee period operation ≥ 15 years.
Another option to hide the circuit is to place it in a baseboard for heating pipes made of plastic. Shapes and colors come in different shapes and can be chosen to suit any design concept.
When the boiler room is not in the house, the question arises of how to insulate heating pipes in the ground.
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, its average consumption is 0.5 l/m. sq.
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 professional builders this is confirmed), 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 material contains multi-composite acrylic polymers, dispersed foam glass granules, 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. Optimal values vapor permeability of this material is comparable to similar values inherent in quality paint for facades. Material "Corundum" in any of its modifications is today best choice to ensure high-quality thermal insulation at minimal cost.
Thermal insulation Corundum technical characteristics, reviews
Thermal insulation Corundum has high technical characteristics. There are positive reviews about liquid insulation. The paint can be applied to any surface.
Thermal insulation Corundum
Not so long ago, a range of construction thermal insulation materials has been replenished with another new product, which combines the best qualities of insulation from different generations. Thermal insulation Corundum, which is produced by NPO Fullerene and sold practically throughout the entire territory of our country, is one of the popular varieties of this material. Let's look at the properties, features and applications of this thermal insulation.
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 outer covering modules and spacecraft designed 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 unusual composition makes liquid insulation, truly 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 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 coated with finishing; it has high degree 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.
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 modification. Storage of such material is allowed even at temperatures of -30 degrees. True, in such unfavorable conditions thermal insulation can be maintained for 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 material Corundum Classic is a universal heat insulator, which is used for insulation of 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 produced 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 outer wall buildings with a layer thickness of 1 mm per 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 delete outer layer rust, 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 Corundum Winter is perfect for those cases when the work on thermal insulation of the facade falls on winter time of the year. The coating is intended for objects that require 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 a primer, a fire retardant material and a finish 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.
Areas of application
What can Corundum thermal insulation be used for?
- For insulating walls, both inside and outside the building
- For insulation of facades
- For insulation of floors, including attics and roofing structures
- For thermal insulation of pipelines, both located indoors and those running through open areas.
- For insulating industrial non-insulated tanks, including tanks and refrigerators.
- Thermal insulation Corundum is used where it is not possible to use other types of insulation due to difficulty of access or operational features of the structure.
In conclusion, let us turn to the dry language of numbers, which will confirm the properties of liquid thermal insulation.
So, the thermal conductivity coefficient of thermal insulation Corundum is from 0.01 to 0.02 W. Material consumption is 1 liter per 1 square meter area, the water absorption coefficient is 0.04 grams per 1 cubic centimeter area (indicator calculated for material completely immersed in water for 24 hours).
Density in liquid form is from 450 to 550 kilograms per cubic meter. The material can withstand shock loads of 50 kg per square centimeter. The vapor permeability coefficient is low, it ranges from 0.02 mg/m h Pa. But the material does not allow water vapor to pass through and prevents increased humidity in the room.
So the use of Corundum thermal insulation is not only an application latest technologies insulation with maximum efficiency and ease of application. It also provides protection from moisture, rust, and other adverse and aggressive influences for a period of 15 to 20 years.
Liquid thermal insulation Corundum
Liquid thermal insulation "Corundum" is a white suspension, its composition is an acrylic binder, which is a latex polymer composition, unique fixatives and catalysts, ceramic thin-walled microspheres, the dimensions of which can be 0.01 - 0.5 mm.

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,
- ability to protect surfaces from influence ultraviolet rays and corrosion.
The thickness of the coating layer is approximately 0.5 mm. The application of the heat-insulating layer is carried out using technologies similar to the application of conventional paints and varnishes; it is not difficult to apply Corundum to objects with a 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 when repairs or maintenance are required.
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 conditions. 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 during operation is not prone to changes in thermal insulation characteristics, shape, size, and 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.
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 calculated 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 work in industrial and private residential construction.

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 white suspension, 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, 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 temperature conditions up to -10 degrees. It does not freeze or polymerize when exposed to low temperatures. Note that acceptable minimum indicator application of 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 on 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 influence. 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 good level insulation.
Let's consider the main characteristics of Corundum thermal insulation:
- Thermal conductivity. IN numerical value this figure is 0.0012 W/(m*S). 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 optimal microclimate in 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 is not destroyed by exposure sun rays. Therefore, you can use it even without a protective coating.
- Biological stability. 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 tools. personal protection.
- 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.

The heat insulator is capable of completely filling the micropores of the surface being treated. In this case, the concentration of the 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 phenomena, plaster, brick, concrete - crumble and become covered with cracks.
- 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.
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 condition 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:
- Corundum Classic - 375 rubles per 1 liter;
- Corundum Anticor - 435 rubles per liter;
- Corundum Winter - 540 rubles per liter;
- 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:
- Pouring paint into large capacity 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 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 optimal temperature application - +20 degrees.
- It is recommended to create no more than three layers of insulation to achieve optimal results.
- On complete drying All layers usually take about a day. If hot pipes were painted, polymerization occurs much faster.

Insulation Corundum is a special paint that forms a ceramic thermal insulation coating, which also protects the surface from corrosion.
You need thermal insulation
internal walls of the room, losing a minimum of area. Or maybe you
want to insulate the outside of the building, but in such a way that it does not
Suffered appearance buildings, but also not to spend a lot of money on expensive
cladding materials? Or maybe you need to quickly produce
high-quality insulation any pipeline or tank?
Some people live with
uninsulated walls in cold panel houses simply because
they are afraid of the expensive and difficult process of insulating the walls, and this
true. But in all these cases there is material that can
solve all problems with thermal insulation as quickly and extremely
effective. This material is liquid ultrafine thermal insulation Corundum.
Walking through the specialty markets in
in any region of our country, you can find a great variety of ceramic
coatings for thermal insulation, for example: mascoat, tsm ceramic, thermal
coat, Isollat, Asstratek, Alfatek, etc. But now our scientists have created
a material that has revolutionized the thermal insulation market
liquid coatings, and this material is ultra-thin
heat insulation paint Corundum, completely superior to any other
liquid thermal insulation, and even cheaper than some of them.
The fact that this coating is liquid
gives it a great many advantages over other types
coatings, for example, the possibility of easy application to the façade of a building,
window slopes, roofs, concrete floors, interior walls, and
various pipes, any containers, trailers, cooling chambers or
tanks. To prevent condensation from forming on cold water pipes, and
pipes hot water delivered water to you with minimal heat loss, you
you can coat them with Corundum. Liquid thermal insulation Corundum can withstand temperatures from - 60 to + 250 degrees Celsius, and its service life is more than 15 years!
Ultra-thin thermal insulation Corundum
is the first independent Russian development that is not
someone else's analogue, in the production of which imported
ingredients are of the highest quality, and yet it has
reasonable price. This production has a certificate giving
guarantee to the consumer that the quality of Corundum thermal insulation is always
will be consistently high. The quality of this product is constant
confirmed positive reviews consumers, so quality
thermal insulation Corundum is our pride. By purchasing this material, you
definitely buy it again as it rivals it in terms of
quality-price-durability cannot be achieved by any other material for
thermal insulation.
Today four modifications have been developed
thermal insulation Corundum. A more detailed description of them can be found at
pages on the links, and below will be brief information.
The first modification to be developed was Corund Classic. In general, it’s difficult to call it a modification, because this is exactly the Corundum thermal insulation that was developed for the first time.
Next, a modification called Corundum Anticoror saw the light of day.
Main feature this modification was possible to apply it even
on rusty metal, you just needed to clean off the loose flakes of rust
with a brush, and then it was already possible to fearlessly apply Corundum Anticor,
using the instructions. This modification is a complete
anti-corrosion and thermal insulation coating, and not just a corrosive preservative.
After Corund Anticor, the Corund Winter modification was developed,
the peculiarity of which was the ability to apply it at a temperature
air -10 degrees Celsius. Corundum Winter is the newest
development among ultra-thin liquid materials for thermal insulation.
Other similar materials cannot be applied in ambient conditions.
temperatures down to -10 °C, since their minimum threshold is limited only
five degrees Celsius.
The next modification was Corundum Facade,
which could be applied in layers of less than one millimeter at a time, but
at the same time, its ability to pass steam was no worse than that of more expensive ones
coatings for facades.
Also, two new modifications of Corundum for specialized purposes have now appeared on the market:
The first is Corundum Vulcan - a modification that can withstand operating temperatures up to +540 degrees Celsius.
The second modification is called Corundum
Anti-condensation, which protects the application surface from the formation
condensate more effectively than, for example, Corundum Classic.
This ceramic thermal insulation
has the ability to be applied to any surface due to its liquid
state of aggregation, and, in addition to protection against heat loss, also protects
surface from rust, water and sound penetration, which allows
use this thermal insulation in any of the above cases.
For the first time like this liquid coatings For thermal insulation
surfaces were developed by NASA under US government order for coating
surfaces space shuttles. Further tests showed that
this material can also be used for more “earthly” purposes,
for example, in industry, construction, etc.
Most of all, such thermal insulation
used for application to steam lines, hot water pipes,
boiler room equipment, as well as roofs and walls residential buildings, public and
industrial premises. Moreover, insulation was applied both from the outside
sides of the room and from the inside.
Although the scope of such coatings was much wider than the one in which they were usually used. Liquid thermal insulation
could be used as excellent protection from corrosion, chemical
impact, as well as to reduce heat loss from metal structures.
Here are the most common examples:
Garages and hangars.
Crane beams.
Overpasses and bridges.
Hot water pipes.
Gas and steam pipelines.
Air conditioning systems.
Cold water pipes to prevent condensation.
Boiler equipment and hydrants.
Heat exchangers.
Steam boilers.
Underground and surface oil pipelines, as well as oil storage facilities.
Hot mixing chemicals tanks.
Water storage.
Cooling chambers.
Internal coating of military and special vehicles.
Refrigeration chambers.
Auto and railway tanks with liquids.
Subway and train cars to provide sound insulation in addition to thermal insulation.
Ship's engine rooms.
Covering ships, boats, etc.
In addition to this list, the scope of use is as follows thermal insulation
growing all the time. If we look more creatively at where it can be
apply, then options for using ultra-fine liquid ceramic
thermal insulation will increase significantly.
The use of liquid thermal insulation
coating under normal conditions, provides a guarantee of at least 10 years of service,
if it is applied externally, and 25 years - if it is applied internally
sides of the room.
Below will be listed the advantages of ultra-thin ceramic thermal insulation CORUND:
This coating is easy to apply to
absolutely any surface, be it concrete, metal, brick, plastic or
any other coating, incl. various equipment with uneven
surface.
It adheres absolutely easily to propylene, metal or plastic, which gives the surface protection from air and water.
The material does not allow water to pass through and
immune to the effects of salt dissolved in water. One hundred percent
protects the surface from precipitation, moisture and sudden temperature changes.
Reduces heat loss and provides protection against corrosion.
Prevents the appearance of condensation on the treated surface.
For good thermal insulation
a layer 1 millimeter thick is sufficient. This layer replaces
half a centimeter of mineral wool insulation or brickwork in 2
brick thick.
Insulation can be applied to a surface of any shape.
Due to the low weight and lack
the need to apply a large amount of insulation, absolutely not
creates loads on the treated surface.
Protects metal structures from deformation under the influence of temperature.
Up to 85% of the radiant energy incident on it is reflected from the insulation.
No need to stop working
equipment for inspecting processed equipment or parts, which, in
in turn, reduces the cost of compensating for downtime of this
equipment.
The insulation is immune to ultraviolet radiation.
Since liquid thermal insulation is quite
quickly applied, this reduces labor costs for its application - its
can be applied very quickly with a brush or special paint
equipment.
If the coating is damaged, it is very easy to restore.
Does not burn. But not only does it not burn, but
it also reduces the rate of fire spread, since at temperature
flames above 800 degrees, the thermal insulation Corundum begins to release oxide
nitrogen and carbon, which give the slowing effect.
Liquid thermal insulation Corundum is environmentally friendly, does not emit toxins and does not contain dangerous volatile compounds.
Resistant to solutions of salts, alkalis and acids.
It has a relatively low price with the effectiveness of more expensive materials.
It has the lowest thermal conductivity of all insulating materials - 0.001 W/m °C (at ambient temperature+20°С).
Ultra-thin ceramic thermal insulation Corundum
is a mixture with many ceramic and vacuum balls,
inside which there is a vacuum, which are suspended in
liquids containing acrylic polymers, synthetic
rubber and pigments. This composition gives this thermal insulation an unprecedented
flexibility, adhesion and light weight.
Thermal insulation is a homogeneous white mass, after drying it forms a thin insulating coating.
Thermal insulation Corundum can be diluted with water for use in unventilated areas.
Can be applied to rubber
plastic, metal, concrete, glass, brick, wood and so on. Requirements,
which are presented to the surface before application are not large - it
must be clean, degreased, free of rust (excluding Corundum Anticorrosive) and
have an acceptable temperature for this modification.
Ultra-thin thermal insulation Corundum
can be applied either with a brush or with a special paint sprayer
equipment. In the second case, the highest
performance.
The thickness of one layer of thermal insulation can
reach a maximum of 0.4 millimeters. 20 minutes after
A layer is applied and a waterproof coating is formed on it. One layer
dries in about a day room temperature. The next layer is applied
only after the previous one has completely dried.
Insulation consumption when applied by roller
is approximately 0.5 liters per square meter. If
insulation is applied using special painting equipment, then the consumption
is approximately 0.4 liters per square meter of surface.
More or less consumption depends on the type of surface and the required
thermal insulation.
Applying the material is as easy as painting any surface regular paint or varnish.
Ultra-thin ceramic thermal insulation Corundum is available in containers in the form of plastic buckets with a capacity of 20 liters.
