If we say unequivocally that AstraTech is a liquid heat insulation that is applied by the type of paint, but acts as a powerful thermal barrier, it means not revealing to the full all the qualities of the material. Controversial and contradictory opinions about the possibilities of liquid heat insulation can be considered as an answer to the question: "How to produce a thermal insulation using this type of coating"

About the application of AstraTech thermal insulation
The main task of modern insulation materials is to prevent deterioration of the properties of enclosing structures, in particular walls.
To create a stable heat-insulating layer for freezing of walls, accumulation of condensate moisture, cracking and opening of joints helps the liquid astretek insulation. Therefore, AstraTech thermal insulation is not only energy-saving nanotechnology, which has been talked about lately, but we also add that it is possible to save energy resources. What is AstraTech and where can it be successfully applied?
Structure and composition of the Astrakht thermal insulator
Thermal insulation coating AstraTech is a high-tech material, the structure of which is a homogeneous suspension or mastic. The composition of liquid thermal insulation includes the following components:
• acrylic binder - polymers
• special fillers - expanded perlite
• pigmenting, inhibiting and flame retardant additives (titanium dioxide, zinc oxide, quartz, butadiene-styrene latex).
Covering the astrakhk in consistence resembles a thick paint that can be applied to the surface with your hands using a brush, spray or spatula. After drying of AstraTech thermal insulation, a reliable elastic coating is formed, which has heat-protective and anticorrosive qualities. For reference: the layer of a cover of a heater in 1 mm is capable to provide similar теплоизоляционные properties of a heater from минваты of 60 mm or brickwork in the thickness to 380 mm.
And the microporosity of the structure of the heater can be considered ideal. For coating with a liquid heater is characterized by stable adhesion, weather resistance and vapor permeability. Naturally, in the presence of such a quantity of positive qualities, the choice of a liquid insulation will be made in favor of astrakht thermal insulation.
Technical characteristics of liquid thermal insulation
The main technical characteristics of astraxtes are:
• the density of the material at the working application temperature of 20 degrees - 595 kg / m3
• density of the formed film - 350 kg / m3
• coefficient of thermal conductivity of the material - 0,023 W / (m ° C)
• coefficient of thermal conductivity of the coating layer - 0.0012 W / (m ° C)
• adhesion of the coating to the concrete and brick surfaces - 08 MPa.
• drying time to stable film formation - 24 hours.
According to the chemical composition, according to GOST 12.1.007-76, the hazard class is 4. Thus, due to good technical characteristics, the scope of application of AstraTech is not limited only to the thermal insulation of walls.
Field of application Астратек
Due to the insignificant coefficient of thermal conductivity and microporosity of the structure, the liquid heat insulator AstraTech can be used for metal, concrete, brick bases and building materials, as well as technological pipelines and air ducts. The operating temperature and the characteristics of Astrakhan allow the work to be carried out at temperatures from minus 60 ° C to plus 260 ° C.
And the shape of the working surface for application can be simple and complex geometry.
The working layer of liquid thermal insulation AstraTech is capable of:
• eliminate the freezing of joints of walls, eliminating "cold bridges"
• isolate any work surface, even hard-to-reach
• significantly speed up and simplify any thermal insulation work
• Convenience and practicality of applying liquid thermal insulation does not create a weight load on the structure.
Liquid insulation is applied layer by layer on the previously prepared surface. Technologically, the thickness of one layer of thermal insulation is 0.4 mm. The standard material consumption, taking into account the single-layer coating, is equal to 1L. insulation for 1.5 - 2.0 square meters of working surface.
By the complexity of applying the liquid insulation, the process can be compared with qualified painting works. The price of astrathek is democratic and allows to produce heat insulation with minimal financial costs, especially as the material is packed into a convenient container (plastic bucket) for 3, 10, 20 liters.
How to apply liquid insulation
How to properly apply the liquid insulation of Astrakhan, thoroughly described in the instructions for use from the manufacturer.
We will only remind you that the process of applying liquid thermal insulation consists of the following stages:
• the preparatory
• surface primers
• application of thermal insulation layer
• Tints.
To work with liquid heat insulation AstraTech it is necessary to prepare the surface. The working surface is cleaned of dust, old coatings, cracks and cracks with a slight degree of openness. Friable areas and cracks dilate, then close the plaster again. Alignment of existing defects (deep cracks and chips) is done with the application of putty for external works. If necessary, a layer of putty is sanded with sandpaper. Before the subsequent application of liquid thermal insulation, it is necessary to make a surface primer.
For these purposes use a primer of deep penetration for 2 layers. If the surface is dense concrete, silicate brick or ceramic facing brick, then as a primer it is recommended to give a primer of the "concrete-contact" type.
For the application of the thermal insulation layer of the liquid insulation, comfortable conditions for application are needed, namely: absence of strong wind, rain or frost. The residual moisture should not exceed 10 percent.
A ready-to-use solution of liquid heat insulation before use is mixed using a low-speed drill to a homogeneous mass. Thermal insulation is applied layer by layer using a brush, a spray gun of any type, or a spatula. The thickness of the layer of thermal insulation can reach 0,5 mm. The total thickness of the coating is calculated from preliminary data. It is recommended to apply the mortar with a spatula or spray.
application of thermal insulation with a spatula
It is preferable to apply a layer of liquid heat insulation with a spatula using plaster, porous concrete and putty previously applied. To apply thermal insulation AstraTech use a wide spatula, the thickness of which can be 1.0 mm. The process of applying liquid thermal insulation is no different from the traditional ways of filling, so it does not cause difficulty in self-operation.
application of thermal insulation liquid using a sprayer
For work, you can use a sprayer of any kind:
air or airless. How is the application of liquid thermal insulation itself shown in this video.
