GF-021 Kronos — alkyd anticorrosive primer for metal and wood
GF-021 primer from AO “KRONOS SPb” for steel structures and equipment under alkyd and oil enamels, dries in max. 35 min at 105 °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.
