RAL1021 colza yellow epoxy polyester Powder Coating for switchboards
Feature:
Good bond ability and mechanical performance
Smooth and glossy
Certified chemical resistance
Better heat resistance and light resistance than pure epoxy powder
The most common hybrid powder coating consists of a blend of carboxyl polyester and epoxy resins. Depending upon the formula the ratio of polyester to epoxy ranges from 50:50 to 70:30. Why, you wonder, would a chemist vary this ratio? There are a number of factors that influence this choice.
