Full Product Information:Type: GF-021 primer is a suspension of pigments and fillers in alkyd varnish with the addition of solvents, stabilizing agents and the desiccant. Benefits: - Coating has good adhesion to metal; - Forms a salt resistant primer coating, resistant to the action of mineral oil; - The primer coating is resistant to temperature fluctuations from -45 ° C to + 60 ° C. Surface preparation: metal surface before applying the primer must be thoroughly cleaned of rust, scale and other impurities (must be removed incision burrs, weld spatter, sharp edges, corners, battlements and welds; on the surface should be no grease, marking paint and other substances such as mineral pollution, water-soluble salts that affect the quality of surface preparation), tipped sandpaper (allowed to use sandpaper grit size 4 or 5 in accordance with GOST 6456), degreased with white spirit (GOST 3134) or nephras S2-80 / 120 (TU RB 100006485.148) and dry thoroughly. The most thoroughly be cleaned surface zone of welds of up to 3 cm from the flux residues, and dross alkaline oxides formed during welding. To improve protective properties of the surface is recommended to clean the sand or grit blasting to purity oxides from 1 - 2. The color of the produce, not later than 4 hours after surface preparation. In welds, end edges and hard to reach areas before painting is done applying a primer with a brush in the form of "strip layer." Previously painted surfaces are cleaned from fragile layers of old flooring, peel off the old paint is removed, the entire surface is cleaned sanded (allowed to use sandpaper grit size 4 or 5 in accordance with GOST 6456), dedusted, degreased and dried. It is recommended to control a small area of the surface staining. To eliminate the condensation temperature of the painted surface must be above the dew point temperature at least 3 ° C. Unpainted wooden surfaces must be free of tar, dried, tipped to remove lint sandpaper (allowed to use sandpaper grit size 4 or 5 in accordance with GOST 6456) and freed of dust. Before applying the enamel coating layer primed surface must be sanded. With the previously painted surface must remove various impurities, completely remove loose coating, the surface is sanded and de-dusted. Coating: should be thoroughly mixed before application of the primer, if necessary, diluted to a viscosity solvent, xylene, or a mixture of one of these solvents with mineral spirits at a ratio of 1: 1 by weight, solvents RS-2, 649, 650. To paint products in the electric field primer diluted diluent ER-4B. The primer is applied by pneumatic and airless spraying, spraying in electric field, the jet flow coating, dip coating, brush. Drying times to 3 monolayer coatings extent at (20 ± 2) ° C - not more than 24 hours. The thickness of the dried coating monolayer 15 - 20 microns, blast or shot peening the coating thickness must be increased to account for the degree of surface roughness Ra. Primer consumption per single-layer coating 60 - 100 g / m2 excluding the surface preparation, application method, staff development and other factors. Precautions: When carrying out painting work in confined spaces, as well as after their completion requires careful ventilation. Rubber gloves are used to protect the skin of hands. Storage: The primer is 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.
