Powder coating’s polyester formulation enables uniform film builds on complex parts, surfaces

PPG Industries’ industrial coatings business has introduced ENVIROCRON® HTE (high-transfer-efficiency) powder coating, featuring a proprietary bisphenol A (BPA)-free polyester formulation that offers a fast application build rate while providing uniform coverage on complex parts and surfaces and reducing material waste.

Engineered for appliance, architectural, wire goods, and extrusion applications, the coating is engineered with a cross-link polymer that enables it to penetrate and apply evenly to metal parts and product assemblies with recessed cavities; odd shapes; and open, uneven, or geometrically complex surfaces such as refrigerator racks, patio tables, and architectural components.

The coating also can achieve first-pass transfer rates of 85 percent and better, which makes it suitable for spray-to-waste coatings applicators that want to reduce product loss. It cures in 10 min. at 350 degrees F.
