Brief information on the varnish Avers-Plast
The two-component neutral varnish “Avers-Plast”, created on the basis of soluble fluorine-containing polymers, is designed to produce highly effective protective coatings for metals, fiberglass, plastics, ceramics, wood, rubber, glass and other materials.
Varnish is one of the best dielectrics used in electronics. It possesses the most outstanding properties as a dielectric for high and ultra-high frequency techniques. The dielectric properties of the varnish are practically independent of either frequency or temperature.
The temperature of operation of the varnish is from -80 ° C to + 280 ° C, with short-term exposure - up to + 380 ° C.
Coatings based on this varnish have high anticorrosive and protective properties, do not swell in water. The varnish is resistant to acidic and alkaline environments (98% nitric acid, 37% hydrochloric acid, 50% acetic acid, 50-98% sulfuric acid, 50-90% phosphoric acid, 40% - sodium hydroxide solution), and are also resistant to aggressive gases and vapors containing hydrogen fluoride, oxidizing agents and other aggressive components.
Studies have been conducted on the effects of concentrated acids - nitric, hydrochloric and sulfuric, as well as sodium hydroxide on electronic boards with micro-components coated with fluoroplastic and caponlac.
When the boards were kept for 7 days, in the specified aggressive media, all metal parts were dissolved on all boards covered with caponlac, and the fluoroplastic varnished ones, after washing, were found to be operational without changing the operating parameters.
Studies on the use of varnish for coating propeller blades and hulls of ships and small vessels in Germany in 2017 - 2018. showed that it can be used to protect metals from corrosion and surface deposits of organic origin in sea and river water.
It can also be effectively used when coating electronic components and products in general to protect against corrosion in aggressive and salt-containing environments. The varnish can also be used when exposed to the open sun, which contains ultraviolet rays and ambient temperature changes.
Application of varnish coatings:
Avers-Plast” varnish coatings can be used for protection against corrosion, marine and river transport bodies, their propeller blades, gas ducts, fans, exhaust hoods, probes, tanks, tanks, tanks and other equipment operating in aggressive environments in various chemical industries as well as very high-quality electrical insulating and heat-resistant coatings in electronics, optics, nuclear energy and in the enterprises of the energy complex, in the food industry, for the protection of containers and filters When the production of petroleum products and food products.
The varnish has a low degree of crystallinity, and is one of the best moisture-proof varnishes. The moisture permeability of coatings from it is 0.16 ∙ 10-15 kg / (cm ∙ h ∙ Pa), it is 30 times less than the moisture permeability of polyethylene, 40-60 times less than the moisture permeability of epoxy varnishes. Varnish coatings have good anticorrosive, dielectric and optical properties, and weather resistance. It will be especially effective during long-term storage of ammunition of all calibers.
The coating is well washed from radioactive contamination. It has a very low coefficient of friction, in comparison with other plastics and polished materials, and is equal to 0.001 - 0.004 (for comparison, ice on ice is 0.01 - 0.03, ice skates are 0.015).
These physico-chemical properties of the varnish can be used as coatings against snow sticking and the formation of icicles. Roofs made of metal, tiles and other materials, varnished, on a fat-free surface will not form an increase in snow cover on the roofs, snow will immediately roll off and blow off with the wind.
For a more detailed consideration of the behavior of varnish coatings, a series of experiments were carried out with the coating of metal surfaces, slate and tile and installed at an angle of 30 - 60 ° (as applied to the average angle of the roofs of cities and towns).
During the 3 winter months in Tyumen there was no sticking of snow cover to the roof covered with AVERS-Plast varnish, and during the whole autumn-winter-spring period there were no ice growths (icicles) from the gutters and the roof as a whole.
When varnishing plumbing fixtures (toilets, sinks, bidets, etc.), before installation, which will increase their shelf life and cleanliness. There will be no deposition of rust, limescale and just dirt.
ATTENTION! Do not varnish the inner surfaces of bathtubs, floors of showers and pallets. This can cause a person to fall when taking water procedures!
The use of varnish allows you to save the basic properties (moisture and chemical resistance, elasticity, release properties, weather resistance, etc.) and at the same time significantly increases the adhesion of coatings.
Adhesion to metals increases 4-6 times and persists with prolonged exposure (up to 500 hours) to boiling water. The relatively low hardening temperatures of the compositions allows them to be applied not only to metals, but also to various other materials, including ceramics, wood, plastics, rubbers.
Also, varnish can be effectively applied to historical and architectural structures, including monuments. It completely protects surfaces from moisture and other aggressive chemicals. The surface of the varnish is easy to clean even with water.
In the near future, coatings will be tested on the external parts of aircraft of all kinds, including civilian aircraft for anti-icing issues. Studies will also be conducted to increase the wear resistance when introducing varnish into the composition of nanomaterials and diamond nanocrystals.
The consumption of finished varnish, depending on the number of application layers, is calculated per 1 kg:
- in one layer - 50 m
- in two layers - 40 m
- in three layers - 30 m
The thickness of the multilayer coating, depending on operating conditions, ranges from 30-150 microns. The thickness of a single layer coating is 10-30 microns, depending on the application method. Lacquer consumption 1 kg. 50-10 m
