OS-51-03 CERTA radiation-resistant (TU 84-725-78) — composition for concrete and NPPs

Other anticorrosion materials

A radiation-resistant and decontaminable coating is obtained when OS-51-03 CERTA is overcoated with KO-921 silicone varnish (GOST R 51102-97). The composition is applied to concrete, brick, monolithic and precast reinforced concrete, in tunnels and NPP power unit rooms — in at least 3 coats, the first of which is the priming coat. TBT, PBT or AGM-9 hardener is added to it, the pot life of the mixture is 24 h at 20 °C; the service temperature is from −60 °C to +300 °C.
