PPG Debuts Envirocron HTE High-Transfer-Efficiency Powder Coating

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

Engineered for appliance, architectural, wire goods and extrusion applications, Envirocron HTE coating is engineered with an exclusive 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, architectural components and other finished goods.

Envirocron HTE coating also can achieve first-pass transfer rates of 85 percent and better, which makes it ideal for spray-to-waste coatings applicators that want to reduce product loss.

Shelley Verdun, PPG powder product manager, industrial coatings, said Envirocron HTE coating is engineered to help applicators increase throughput, reduce waste and more readily achieve environmental compliance. “This product is unique among powder coatings because it enables applicators to achieve higher transfer-efficiency rates based on product chemistry rather than the application method, equipment or skill of the operator,” she explained. “Not only does that have the potential to improve the quality of the coating, it also can offer applicators a greater degree of control over cost and quality in their production processes.”

Envirocron HTE coating cures in 10 minutes at 350 degrees F, and it is available in a standard formulation to meet American Architectural Manufacturers Association (AAMA) 2603 specifications as well as in an ultra-durable version to achieve the AAMA 2604 standard. PPG also manufactures the coating in a wide range of colors and gloss ranges.
