Pigmokron — fast-drying alkyd 3-in-1 primer-enamel for metal and rust
One-component 3-in-1 primer-enamel for bridges, supports, wagons and machinery, applied over rust at temperatures from 0 °C.

GF-021 made by AO “KRONOS SPb” is a primer based on an alkyd varnish with pigments, fillers and a drier, red-brown or light grey. It is applied to steel structures and equipment, as well as to wood and boards, and overcoated with pentaphthalic, glyphthalic and oil enamels or water-dispersion paints. At 20 °C the primer dries to degree 3 in max. 24 h, at 105 °C in max. 35 min; the film withstands water and 3 % NaCl solution for at least 24 h and industrial oil for at least 48 h.
