SK-PROTEKT enamel — polyurethane topcoat for metal and concrete
Semi-gloss RAL enamel for bridges and chemical plants; in a system with SK-EPOKSID-MIO it lasts 10 years in a urea environment.

Local defects of the MASTIKOR coating are eliminated with this repair kit — both in the factory and in the field. The paste-like polyester-based base is mixed with the hardener in a ratio of 100 : 35 by weight in small portions and applied manually with a spatula in one or several coats at temperatures not below +5 °C. The pot life of the mix is 15–20 min, full cure takes 3 days at +20 °C, and adhesion to steel is at least 7.0 MPa.
