OS-51-03 CERTA radiation-resistant (TU 84-725-78) — composition for concrete and NPPs
Radiation-resistant decontaminable organosilicate composition for concrete, brick, reinforced concrete, tunnels and NPP power unit rooms.

The outer surfaces of heat and steam pipelines laid in ducts, tunnels and above ground, heat exchange equipment and heating network supports are what this heat-resistant organosilicate composition is intended for. The coating works from −60 °C to +300 °C and is applied without primer by brush, roller or air spray in at least 2 coats with an interval of at least 1 h at +20 °C between them. Up to +100 °C the material cures by the cold method, and at higher temperatures by the hot method.
