SK-PROTEKT enamel — polyurethane topcoat for metal and concrete
The SK-PROTEKT enamel based on a lightfast aliphatic polyisocyanate forms a semi-gloss coating of at least class IV per GOST 9.032 that is resistant to UV radiation. It is applied over the SK-PROTEKT primer, the zinc-rich SK-TSINK and SK-EPOKSID-TS, over SK-EPOKSID-MIO, and on concrete over the penetrating SK-BETON. The enamel is included in the “Technological guidelines for painting steel structures of railway bridges” of JSC RZD; the SK-EPOKSID-MIO + SK-PROTEKT system is designed for OM-1 and OM-3 conditions, including a urea environment, for 10 years.
