Powder Coatings - Polyester Resin Powders
Powder coating is becoming increasingly more popular due to a variety of benefits over liquid paint processes and higher expectations from consumers for products that last. Powder coating processes improve overall coating performance, reduce the cost during application and can eliminate all VOC (volatile organic compounds), HAPs (hazardous air pollutants), and hazardous waste generated during application.
For thermoset polyester resin powders, there are two basic categories — hydroxyl and carboxyl terminated. Each variety of polyester resin uses different types of cross-linkers in composition of the binder system. A quick table details the combination of polyester resin & cross-linker type:
