Type: Fast drying one - component priming enamel based on modified alkyd resins with the addition of high anticorrosive pigments and fillers, and functional additives desiccant and solvent.
Scope: primer enamel "Praymkout T" is recommended for the dyeing of products that have to meet high requirements for corrosion resistance and durability of paint coating, used in industrial environments and is intended for application by airless spray or combined.

- coating of priming enamel dries quickly;
- high quality included in the primer enamel coating the resulting pigment imparts excellent decorative properties - is formed smooth matte finish;
- priming enamel has excellent adhesion to the metal;
- a tailor formula and a binder content in the composition anticorrosive protection of ferrous metal products operating at temperatures from - 60 ° C to + 100 ° C in various environments;
- the thickness of a single layer of the dried coating is less than 70 microns;
- two - layer coating replaces the priming enamel coating systems, consisting of one primer layer and two layers of enamel;
- priming enamel forms a weatherproof, water resistant, resistant to the effects of salts, mineral oil coating;
- primer one - component enamel, a paint has good properties.
The aforementioned advantages simplify the process as much as possible staining of metal surfaces.
Surface preparation : Paint Lifetime with prolonged retention decorative and anticorrosion properties largely depend on the degree of preparation of the surface to be coated product. For painting primer enamel product surface preparation is carried out in accordance with the technical regulations on the requirements of the product, or GOST 9.402 STB ISO 12944 - 4.
With metal surfaces must be removed by oil, grease, marking ink, dirt and other substances such as mineral pollution, water - soluble salts that affect the quality of surface preparation. It is necessary to remove the sipe, burrs, weld spatter, to round sharp edges, corners, tine and welds. Then, the surface should be thoroughly cleaned of rust, scale and other impurities, freed of dust, degreased and dry. The most thoroughly necessary to clean the surface in the zone of welds of up to 3 cm from the flux residues, and dross alkaline oxides formed during welding.
To improve the protective properties of the surface should be pre - cleaned sandblasting or shot peening treatment to the extent of oxide 1 - 2 according to GOST 9.402.
The color should be made no later than 4 hours after surface preparation. Coloring is not allowed during precipitation, as well as on wet and icy surfaces.
In welds, end edges and inaccessible places before coloring is performed applying ground enamel with a brush as a "strip layer".
Previously painted surfaces purified by the fragile layers of the old coating, delaminated old coating removed, the entire surface is cleaned mechanically, dedusted, degreased and dried. If not known kind old paint coating, it should be checked for compatibility (recommended to control staining small surface area). In the case of blistering or peeling of the old coating should be removed.
To eliminate condensation substrate temperature should be above the dew point temperature of not less than 3 ° C.
Reduced quality surface preparation leads to a decrease in coating durability.
Coating: Before applying ground enamel is thoroughly stirred, filtered, if necessary. Priming enamel "Praymkout T" applied by airless spray or combined, and small sections - a brush.
Possible to use solvent AK (TU BY 500021625.201), xylene (GOST 9410), o - xylene (TU BY300042199.015), an oil solvent (GOST 10214) in an amount of not more than 5% by weight of a ground enamel. Primer enamel is applied in one - two layers on the prepared surface at a temperature of 5 - 35 ° C and relative humidity of 80% . Drying of each layer is not less than 2 hours at a temperature (20 ± 2) ° C and relative humidity (65 ± 5)% .
The recommended thickness of the dried coating monolayer - not less than 70 microns, and after sandblasting or peening the coating thickness must be increased to account for the degree of surface roughness Ra. When changing the temperature and relative humidity of the drying primer enamel is increased.
Two - layer enamel coating of priming replaces coating consisting of a primer layer and two layers of enamel.
Drying time single - layer coating according to the temperature shown in the table.

The thickness of the dried coating monolayer - 60 - 70 microns.
Consumption primer - a single layer of enamel on the dried coating is 210 - 250 g / m² exclude complexity surface as surface preparation, application method, soil colors - enamels, staff, and other factors.
Lifetime : primer coating enamel "Praymkout T" thickness of 140 - 150 microns deposited on a metal surface maintains the protective and decorative properties under moderate - cold climate at least 15 years in tropical climates - at least 3 years.
Precautions: during painting work in confined spaces, as well as after their completion requires careful ventilation. For hands protecting use rubber gloves.
Storage: Priming enamel stored in a tightly closed container, protected from moisture and direct sunlight and away from heating appliances out of reach of children. Keep away from fire. In the case of storage at low temperatures priming before application of the enamel incubated in a warm room for at least 24 hours.
