The advantages of Polyethylene Powder coating include more thickness coatings without running or sagging, much lower emissions of volatile organic compounds, and faster production cycles. In most cases, key elements of powder paint systems are gas-fired catalytic infrared systems or natural gas-fired convection ovens. The usage of Polyetylene powder for products finishing is expanded into new markets. These finishes are expanding from metal products to other surfaces.
Powder paints systems were introduces about more than 30 years ago. Since then, a large growing number of products manufactures have taken the step away from spraying liquid painting. Liquid has inherent challenges, which including the need for very expert application in order to getting a uniform coating without sagging or thin spots. Another is the ever-tightening requirements to capture and reduce volatile organic compound emissions from solvent carries to comply with occupational health rules and strict VOC air emission.
Early adopters of the powder coating technique included manufacturers of appliances, lawn and garden equipment, metal furnishings, agricultural machinery and tools. Today, an estimated 15% of industrial coating is done with powder, and that number is growing rapidly. Expanded into new applications is feeding that growth.
Only curing is the key.
