NH7805 is a hydroxylated polyester resin for polyester/isocyanate powder coating system, suitable for polyurethane powder coatings.
Polyurethane powder coatings are developing into the mainstream of powder coatings, accounting for an increasing proportion of powder coatings. Because polyurethane powder coatings have excellent weather resistance, excellent physical and mechanical properties and corrosion resistance, the coating film is bright and plump, resistant to Abrasion, scratch resistance, solvent resistance, good leveling and strong adhesion. It is widely used in refrigerators, washing machines, air conditioners and other household appliances, as well as high-end furniture, automobiles, motorcycles and other industries.
