OGRAX-VENT air duct fire protection system (OGRAX-BM + OGRAX-K adhesive)
Fire protection of air ducts with OGRAX-BM foil-faced basalt material on OGRAX-K adhesive; EI 60 and EI 90 ratings.

OGRAX-MSK is based on intercalated graphite with a polymer and mineral fillers in an organic solvent. This single-component paint is designed for the open atmosphere, damp unheated and heated premises, humidity up to 100% and temperatures from −60 to +60 °C; the coating is resistant to oil and petrol. Fire resistance of steel structures is R45–R90. Work can be carried out from −25 °C, with or without primer; application before the structures are erected is permitted. The colour is dark grey.
