KO-8104 CERTA — heat-resistant primer-enamel for metal, concrete and tanks
Silicone primer-enamel up to +700 °C for metal and concrete: chimneys, flue ducts, pipelines, boilers, vessels and tanks.

The distinctive task of OS-52-20 is surfaces subject to abrasive wear and heating: steel structures, pipelines, chimneys and flue ducts, boiler equipment, power line towers. The coating works from −60 °C to +400 °C (red, blue and yellow up to +250 °C) in categories C1–C3 per ISO 12944-2. On metal it is applied without primer or over CERTACOR 01, on concrete and reinforced concrete over CERTACOR Polisil, in at least 2 coats.
