A topcoat enamel for cold galvanising systems: synthetic resins with flake aluminium form a silver, UV-resistant barrier coat. It is applied in 1–2 cross coats over primed or unprimed surfaces of steel structures and equipment, including at temperatures down to −20 °C. The declared service life of the coating is up to 35 years, resistance to static exposure to water is 100 h and to 3 % NaCl solution 72 h; the manufacturer publishes a test report.
