Can polyurethane paint be used outdoors?

1. What kind of paint is polyurethane paint?

Polyurethane paint is a two-component paint, including main paint and curing agent. The paint film has excellent mechanical properties and good adhesion. It can be matched with a variety of primers. The coating is full of gloss, and can be adjusted to high gloss, flat gloss, matte gloss, low gloss, etc. Polyurethane paints mainly include polyurethane topcoats and acrylic polyurethane topcoats. In industrial anticorrosion, the application environment is different. There is a big difference between the two in terms of weather resistance. Therefore, they need to be carefully distinguished.

2. Can polyurethane paint be used outdoors?

Polyurethane topcoat is suitable for metal protection in indoor environments, but not suitable for outdoor use. Generally, it is matched with epoxy primer and polyurethane primer. It is applied to steel structures, machinery, equipment, machine tools, instruments, chassis, pipe fittings, and metal parts. Wait.

Acrylic polyurethane topcoat is very suitable for painting in outdoor environments. The paint film has excellent outdoor weather resistance, UV resistance, and the paint film is intact without chalking. At the same time, the coating has color and gloss retention properties, which can maintain beautiful for a long time. Exterior. Acrylic polyurethane topcoat is particularly suitable for anti-corrosion coating of steel structures, mechanical equipment, engineering machinery, vehicles, ports, bridges, pipelines, etc. in outdoor environments.

Polyurethane paints are mostly topcoats, so in anti-corrosion and anti-corrosion coatings, it is necessary to match various industrial anti-corrosion environments with suitable primers to form a complete protective coating.

Polyurethane paint has excellent performance. Before choosing coating products, it is necessary to analyze the coating environment and adopt a reasonable supporting system, so as to ensure the smooth development of anti-corrosion projects and achieve good protection purposes.
