TGIC Polyester Resin NH3387 with Low Costs and Good Leveling for General Industrial Products
NH3387 is a saturated carboxyl polyester resin for applications of polyester/TGIC powder coating system, it is designed for general industrial powder coatings, which is cost-effecive and well-performed.
Different types of saturated polyester resins with different properties can be synthesized by using different polyacids and polyols, which are mainly used in the manufacture of thermosetting powder coatings.
Using TGIC curing system, it has excellent heat resistance, weather resistance, light resistance, corrosion resistance, chemical resistance and mechanical properties, and is mostly used outdoors, such as construction machinery, heavy trucks, containers and other heavy machinery.
