OS-52-20 CERTA — organosilicate composition for abrasive wear and heat
Organosilicate coating for metal, concrete and reinforced concrete under abrasive wear and heating up to +400 °C; categories C1–C3 per ISO 12944-2.

CERTA’s silver two-component KO-813 enamel consists of a silicone base with aluminium powder and a hardener. It is used on pipelines, oil and gas facilities, steel structures and equipment: heat resistance is up to +700 °C depending on conditions, the decorative appearance is retained up to +650 °C, and the lower limit is −60 °C. The coating is resistant to mineral oil, petroleum products and salts; for media without heating, hot curing for 30 min at 250–400 °C is provided.
