RAL1018 zinc yellow energy savings epoxy polyester Powder Coating for house-hold appliance and furniture
Hybrid powders were conceived by combining two base resins into a thermoset curing scheme. Epoxies typically cured with highly reactive curing agents were instead matched with a specially designed carboxyl functional polyester resin. The overall cost of the binder system was significantly less than a traditionally cured thermoset and the coating performance was pretty decent. The overall performance was somewhere between very hard and chemically resistant epoxy and a softer, very flexible polyester.
Feature:
Good bond ability and mechanical performance
Smooth and glossy
Certified chemical resistance
Better heat resistance and light resistance than pure epoxy powder
