PU series of both amine grease paint and reactive coating can be dried only by adding hardener. PU paint has excellent decorative and protective properties. Its main advantages are good physical and mechanical properties, hard and wear-resistant film, and impact resistance. It has strong adhesion to wood, excellent chemical corrosion resistance, good heat resistance and cold resistance. The film is full and bright. The transparency of varnish and the durability of the whole film are outstanding. Because PU paint has three components before coating, it must be prepared in strict accordance with the process ratio before spraying.
