SK-PROTEKT primer — polyurethane primer for metal and concrete
Two-component polyurethane primer for metal, concrete and reinforced concrete, permitted for containers with bulk food products.

The inner surfaces of tanks for crude oil, fuel oil, oils, condensate, flushing fluid and fire-fighting water reserves are the main area of SK-REZERV, together with steel structures, equipment and pipelines inside the tank. The two-component epoxy compound with an aliphatic polyamine hardener is applied as a stand-alone coating in 1–2 coats; it withstands the stored product at temperatures up to +90 °C and short-term steaming at +180 °C. The material is included in the OVP register of PJSC Transneft and recommended by PJSC NK Rosneft and OOO “LUKOIL-PERM”.
