Epoxy Polyester Curing HH2563 in Low Bake Formulation for Hybrid Powder Coatings
Epoxy polyester resin is composed of hydroxyl-terminated polyester resin and epoxy resin. The two are curing agents for each other. They are the main components of hybrid powder coatings, taking into account the anti-corrosion performance of epoxy resin and the weather resistance of polyester resin. It is commonly used in the coating of indoor household appliances and the surface coating of electrical instruments and switch cabinets.
