OS 51-03 CERTA for heating mains — heat-resistant organosilicate composition to +300 °C
Organosilicate composition for the outer surface of heat and steam pipelines laid in ducts, tunnels and above ground, up to +300 °C.

Certacor 110 is a stand-alone concrete protection system: the polyorganosiloxane primer-enamel is applied in at least 3 coats to a substrate prepared per SNiP 3.04.03-85. It is intended for concrete and reinforced concrete chimneys, tunnels, facades, cooling tower shells, foundations and overhead contact line supports and withstands up to +350 °C. Work is carried out from −30 °C to +40 °C at humidity not more than 80 %; intercoat drying at +20 °C is 30 min.
