KhS-059 Khimtek — primer based on a vinyl chloride copolymer with epoxy resin
Red-brown primer for railway wagons, tank cars, equipment and structures in acid, alkali, salt and aggressive gas media.

YARFAST® PRO is a two-component polyurethane primer-enamel with a corrosion inhibitor that is applied to unprimed metal, including metal with traces of corrosion. It is intended for steel structures, external surfaces of petroleum product tanks, lifting and handling equipment, and agricultural, municipal and road machinery. According to the test report, the coating withstood 1,000 h in salt spray, and durability of more than 15 years under UKhL1 conditions is confirmed by a certificate of conformity. The mass fraction of non-volatile matter is 50 %.
