Coating

Polyurethane coating is a coating with polyurethane resin as the main film-forming substance.

The main application areas of polyurethane coatings are wood furniture coatings, floor paints, automotive refinishing paints, anti-corrosion coatings and special coatings.

The output of polyurethane paint is second only to alkyd resin paint, phenolic resin paint and acrylic resin paint, becoming the fourth largest paint variety.
