Advantages: The primer forms a coating with excellent adhesion to the substrate, resistance to abrasion and mechanical stress. The tread protection mechanism of the primer provides durability, anti-corrosion and water resistance of the paint coating complex. Zinc content in the dried coating is not less than 90%.
Surface preparation: Before applying the primer metal surface must be thoroughly cleaned of rust, scale and other contaminants. It is most thoroughly necessary to clean the surface in the weld zone up to 3 cm wide from residues of fluxes, alkaline slags and oxides formed during welding. Welded spatters, chips, grooves, undercuts or sharp protrusions from manual welding, as well as uneven edges, made by gas cutting, must be removed or smoothed by a mechanical tool. Next, the surface is degreased to the first degree (GOST 9.402) and treated with a shot blasting or sand blasting method to the degree of purification from oxides 2 (GOST 9.402) and roughness Rz from 20 to 40 μm (GOST 2789). The coating of the surface roughness Ra.
After 4 hours after surface preparation.
It must be at least 3 ° C higher than the temperature point.
Air temperature should not be below 80%.
Application instructions : Primer for air conditioning spraying or brushing in 1 – 2 coats.
Before applying the prefabricated mix thoroughly. Then enter the hardener E-45 in the ratio: per 100 pm of semifinished primer –
5 pm of hardener, mix, stand for 30 minutes and reduce the amount of water.
The drying time is not less than 3 hours at a temperature of (20 ± 2) ° C and a relative humidity of not more than 65%. The drying time is higher. Drying of the coating is allowed at a temperature of (120 ± 2) ° C – for 30 minutes. The thickness of the dried single-layer coating is not less than 60 microns. It is not necessary to exceed 20 microns. But at the same time, it’s possible to use the strip layer ’.
The primer must be at least 24 hours long.
Periodically it is necessary to periodically mixed to avoid deposition of zinc powder.
It is stored at least 12 hours at a temperature of 20 ± 2 ° C.
The surface coating is an application of the individual surface coating.
The density of the semi-finished primer is 2.9 – 3.1 g / cm³.
After thorough mixing and addition of the hardener, it doesn’t need to be coagulated and has protective properties.
Precautionary measures are taken carefully and carefully. Wear rubber gloves to protect hands.
Storage: Store the container prefabricated in a tightly closed container, protected from moisture and direct sunlight. Keep away from fire!
