Benefits:
fast primer curing at 20 ° C;
It is a condition that the complexion is exposed;
the coating has good adhesion to metal;
the primer forms a water-resistant;
the primer coating is resistant to minus 50 ° C to plus 60 ° C.
Surface preparation : Before applying the primer, the metal surface must be thoroughly cleaned of rust, scale and other contaminants (it is necessary to remove notches, burrs, welding spatter, round sharp edges, corners, teeth and welds; there must be no lubrication, marking paint and other on the surface substances, such as mineral contaminants, water-soluble salts that affect the quality of surface preparation), have been cleaned with sanding cloth (sanding pads of 4 grit or 5 according to GOST 6456), degreased with white spirit
(GOST 3134) or nefrasy – C2-80 / 120 (TU RB 100006485.148) and thoroughly dried. It is the most up to 3 cm wide range of residues from fluxes, alkaline slags and oxides formed during welding. It should be recommended that it be pre-cleaned after 4 hours after surface preparation. Prior to painting on the form of a “strip layer”. The surfaces are cleaned.The entire surface is sanded with sanding cloth (sanding cloth of 4 or 5 grain is allowed according to GOST 6456), dedust, degrease and dry. It is recommended to carry out control staining of a small area of the surface. To avoid moisture condensation, the temperature of the surface to be painted must be at least 3 ° C higher than the dew point temperature.
Unpainted wooden surface should be cleaned of resinous substances, dried, cleaned to remove lint with sandpaper (sanding cloth of 4 or 5 grain size according to GOST 6456 is allowed) and dust free. Before applying the coating layer of enamel primed surface must be sanded. It is necessary to remove various contaminants from the previously painted surface, completely remove the peeled-off coating, sand and dust the surface.
Coating: Before applying, the primer is thoroughly mixed, diluted with solvent (GOST 10214 or GOST 1928), orthoxylene (TU BY 300042199.015) or a mixture of solvent or orthoxylene with white spirit according to GOST 3134 (nefras – C4-155 / 200 according to
TU RB 100006485.147) in the ratio of 1: 1 by weight of the undiluted primer filtered through a grid No. 01H-02H
(GOST 6613). RE-4V diluent (GOST 18187) for painting in the electric field using a VZ-246 VZ-246 (VZ-4) at a temperature of (20.0 ± 0.5) ° С. The specific volume should not be limited to 8 · 104 – 1 · 106 Ohm · m. The temperature of (105 ± 5) ° C is at least 10 hours.It is not less than 20 microns; The thickness of the surface roughness is increased.
The coating layer of enamel is no longer than 24 hours.
The surface coating is an application of the surface coating, application method, personnel qualification and other factors.
Precautionary measures are carried out carefully and carefully. Rubber gloves to protect your hands.
Storage: Keep out of the reach of children. Keep away from fire.
