KO-868 CERTA — heat-resistant primer-enamel for chimneys, furnaces and boilers
Silicone primer-enamel up to +700 °C for chimneys, flue ducts, furnaces, boilers, heat exchangers and process pipelines.

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.
