Polyurethane coating

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.

 

What is polyurethane used for?

Polyurethane is a versatile material that can be used for a wide variety of applications. It is commonly used in the manufacture of plastics, insulation, and coatings. Polyurethane is also used in the production of adhesives, sealants, and elastomers. In addition, polyurethane is often used as a food additive and as a component in medical devices. Polyurethane is an ideal material for many applications due to its durability, flexibility, and resistance to chemicals and abrasion.

A polyurethane coating is a polyurethane layer applied to the surface of a substrate for the purpose of protecting it. These coatings help protect substrates from various types of defects such as corrosion, weathering, abrasion and other deteriorating processes.

 

Marine Polyurethane Clear Coat

Polyurethane can be used to protect a boats paint and to keep the finish on wooden marine vessels visually appealing and more durable. You can apply polyurethane over any type of paint if it is clean and prepared properly. Polyurethane coatings can be applied to exposed wooden surfaces to create a glossy finish that serves to repel water, resist corrosion, and protect from scratches, stains, and UV damage.
