The Many Uses of Polyurethane Paint and Coatings

Polyurethane paint, also referred to as PU paint or PU coating, is a durable, highly-resistant coating used in industrial and architectural coating systems. It is popular in the marine industry and is used for numerous applications including coatings, rigid and flexible foams, and varnishes. It is also used in steelwork, concrete, wood, and other substrates.

Polyurethane is a reaction polymer, a combination of a polyol resin and an isocyanate hardener or curing agent. Essentially, a polyurethane coating is a liquid plastic which dries to form a paint-like film on an underlying substance or layer. Polyurethane paint provides durability, resistance to chemicals, water, abrasion, and temperature, as well as an attractive glossy finish. The most common application of polyurethane is as a solid foam, accounting for approximately 60% of all polyurethane produced.
