The primer-enamel of the Kronos-Deko range removes the need for a separate primer coat: the two-component acrylic-urethane coating is applied in two coats directly onto metal, concrete or plastic. It is used in mechanical engineering, on mining and vessel equipment — tanks, tank cars, pipelines, oil tanks. The material is approved by TsNIIS and included in the STO of AO “TsNIITS”, the recoat interval is 15–30 min, and the coating works from −60 to +60 °C.
