Fast cure Epoxy polyester hybrid HH2682 high Tg excellent flow good mechanical properties
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, which is commonly used in the indoors coating, such as household appliances coatings, the surface coating of electrical instruments and switch cabinets, etc.
HH2682 is a carboxyl polyester resin designed for 60/40 hybrid powder coatings.
◇Basic Features:
Fast curing
Good leveling
Good mechanical properties
Good storage stability
