Kronos-Sprint primer — fast-drying alkyd primer for machinery and wagons
Alkyd primer for railway rolling stock and agricultural machinery under PF-115 and Kronos-Sprint enamels, withstands up to +120 °C.

Tsikron is a primer with cathodic (sacrificial) action: zinc powder and anticorrosive fillers are dispersed in a phenol-alkyd film former. It is used on steel structures of bridges, tanks, pipelines and corrugated metal pipes, including under intensive contact with water. In a system the primer serves as the base under the acrylic enamel “Industrialnaya”, withstands from −60 to +140 °C and dries to degree 3 in less than 1 h at 20 °C. The material has been issued conclusions by TsNIIS, VNIIZhT and TsNIIPSK.
