Polyurethane - the best coating material with so many uses
Polyurethane elastomer is a superior coating material for almost anywhere. It cures in less than a minute and is ready for use straightaway. It is hard-wearing and waterproof and the surface is non-sticky for an almost endless range of uses. Polyurethane elastomer also protects surfaces against corrosion and chemicals.
