SK-TSINK — moisture-curing zinc-rich primer for all-season application
SK-TSINK provides sacrificial protection of steel that is equated to “cold” galvanising: the one-component polyurethane primer cures with atmospheric moisture and contains at least 80 % zinc in the coating. It is applied all year round — at temperatures from −15 to +40 °C and relative humidity up to 98 % — on steel structures, bridges, tanks, pipelines, marine and port structures. The primer works on its own or under epoxy, polyurethane and acrylic coatings: with SK-PUR the system is designed for category C5-M and 20 years, with the SK-PROTEKT enamel for C3–C5 and 20 years.
