Polyurethane coating for metal.
Polyurethane coating (also known as PU coating) on metal provides a thin film, high gloss finish with exceptional weathering performance characteristics. This coating, commonly referred to as poly coating, is used in virtually all industrial markets to provide a smooth durable finish that has superior resistance to corrosion, abrasion, and chemical exposure. Polyurethanes are normally used to topcoat high build epoxy and inorganic zinc.
