Advantages: Enamel forms a smooth uniform matte coating resistant to alkalis, acids and gasoline, which dries quickly in air. It is allowed to use enamel HS-75U gray for painting wooden surfaces without prior priming.
It must be thoroughly cleaned, it must be thoroughly cleaned, it must be cleaned with sandpaper and it must be 4 or 5 in accordance with GOST 6456, degreased and dried. It is a small part of the surface painted. In the case of old coating, must be removed. It must be cleaned up at least 3 ° C.
It can be used to remove the lint, it can be cleaned with sanding sandpaper. Cleaned of sand, dust, sand and dust.
Application : Before applying, the enamel and varnish are mixed, diluted to a working viscosity of 16 – 22 s using a VZ-246 viscometer (or VZ-4) with solvent P-4 or P-4A (GOST 7827) and filtered. Enamels and varnish applied to surface by spraying.
It can be seen that the consumer has been able to control the air flow rate (for example, air temperature, air temperature, air flow, air temperature, etc.).
In the heat of the water, it is kept in the warm room before the application.
The enamel is applied at least 1 layer. Interlayer drying time is not less than 1 hour at a temperature of (20 ± 2) ° C, the last layer – 24 hours at a temperature of (20 ± 2) ° C or 2 hours at a temperature of (60 – 65) ° C.
The thickness of the dried single-layer coating should not be 18 – 23 microns.
The coating is 160-100 g / m², the varnish is 200-260 g / m², the coating layer , personnel qualifications and other factors.
Storage : Enamels and varnish containers should be stored in tightly closed containers, protected from moisture and direct sunlight. Keep away from fire.
Precautionary measures: Persons associated with work protection (workwear, goggles, rubber gloves). Finish, ventilate the room.
It doesn’t have a chemical effect.
