Soil enamel HV-0278: characteristics and application rules

Soil enamel HV-0278 is a unique anti-corrosion material and is intended for the treatment of steel and cast iron surfaces. The composition protects metal surfaces from rust, and slows down the process of destruction of structures already damaged by corrosion. The material has been produced by Antikor-LKM and has been present in the domestic construction market for 15 years.

Soil HV-0278 is a kind of composition in which the primer, enamel and rust converter are combined. The coating composition includes polymerization polycondensation resin, organic solvents and modifying additives.This allows not to resort to the use of different compositions, which significantly saves budgetary funds and reduces labor costs.

The treated surfaces are resistant to harsh environmental conditions, salts, chemicals and reagents. The only limiting condition for the operation of the composition is the ambient air temperature in excess of 60 degrees. The composition, applied in 3 layers, is able to maintain its performance characteristics for four years. The tool has good frost-resistant qualities, therefore it can be used for processing metal structures in conditions of negative temperatures.

Soil enamel HV-0278 is used for anti-corrosion and prophylactic processing of all types of metal structures. The composition of paint machines and units, which are affected by gas, steam, negative temperatures and chemical reagents and which have a zone of soot, rust and scale, not exceeding 100 microns.

Primer covers grilles, garage doors, fences, fences, stairs and any other metal structures.having large dimensions and complex profile. With the help of HV-0278, a base is created for the further application of any refractory coatings.

The composition is used in cases where the mechanical cleaning of metal from rust and scale is impossible or difficult. When carrying out car body repair, the mixture can be used to treat the inner surface of the wings and other parts of the body on which a decorative coating is not required.

The priming mix HV-0278 is manufactured in strict accordance with GOST, and its composition and technical parameters are approved by certificates of conformity. Indicators of conditional viscosity of the material have an index of B3 246, the time of complete drying of the composition at a temperature of 20 degrees is one hour.The amount of non-volatile components does not exceed 35% in colorized solutions and 31% in black mixtures. The average consumption of soil-enamel is 150 grams per square meter and can vary, depending on the type of metal, the size of the damage area and the thickness of corrosion.

The elasticity of the applied layer when it is bent corresponds to 1 mm., the adhesive value is equal to two points, and the level of hardness is 0.15 units. The treated surface is resistant to the action of 3% sodium chlorine for 72 hours, and the rust conversion coefficient is 0.7.

Primer blend consists of epoxy and alkyd resins, plasticizers, corrosion inhibitor, rust converter, perchlorovinyl resin and color pigments. The opacity of the solution varies from 60 to 120 grams per square and depends on the presence of color pigment, staining conditions and the degree of damage to the metal.

The cost of primer enamel is about 120 rubles per liter. The service life of the protective film is four to five years. It is recommended to store the material at a temperature of -25 to 30 degrees, packaging should be protected from exposure to direct UV rays, the bank should be tightly closed.

The application of the primer mixture should be done with a roller, brush and pneumatic spray. It is allowed to dip products into the solution. Before applying the primer HV-0278, the surface of the metal structure must be carefully prepared. To this end, it is necessary, if possible, to remove loose rusty formations, to remove dust and to degrease the metal.

For degreasing, use solvent type P-4 or R-4A. Enamel should be diluted with the same formulations when using the spraying method. When applying a primer with other tools, it is not necessary to dilute the compound. The air temperature during treatment should be in the range from -10 to 30 degrees, and the humidity should not be above 80%.

The first layer serves as a rust converter, the second serves as an anti-corrosion protection, and the third is decorative.

If a two-component coating is formed, the surface is treated with a primer mixture twice. In both cases, the thickness of the 1st layer should be not less than 10-15 microns, and each of the following - from 28 to 32 microns. The total thickness of the protective film, with strict adherence to installation technology, ranges from 70 to 80 microns.

For maximum protection of the metal surface from the damaging effects of corrosion, It is necessary to strictly follow the installation rules and adhere to some important recommendations:

• applying only one layer of material is unacceptable: the mixture is absorbed into the loose structure of rust and cannot form the necessary protective film, as a result of which the metal will continue to break down;
• The use of white spirit and solvents that are not indicated in the instructions for use is not recommended: this can lead to a violation of the performance properties of enamel and significantly increase the drying time of the composition;
• It is forbidden to use a painted surface until it is completely dry: this can disrupt the polymerization process, which ultimately will negatively affect the quality of the protective film;
• Do not use primer-enamel when processing smooth surfaces: the mixture was created specifically for work with rusty rough materials and does not have good adhesion with smooth ones;
• the soil is flammable, therefore processing should not be carried out near sources of open flame, and also without personal protective equipment.

The priming mix HV-0278 is a demanded anticorrosive material and has many positive reviews. Consumers noted ease of use and high speed installation.

Attention is paid to the availability and low cost of the material. The protective properties of the composition are also highly valued: customers note a significant extension of the service life of structures damaged by rust and the possibility of using soil for processing parts of a car body. The disadvantages include not wide enough color palette of the composition and a long drying time of the first layer.
