Advantages of powder coating include thicker coatings without running or sagging, faster production cycles, and much lower emissions of volatile organic compounds. In most cases, key elements of powder paint systems are natural gas-fired convection ovens, or gas-fired catalytic infrared systems. The use of powder coatings for product finishing is expanding into new markets. These finishes are expanding from metallic products only to other surfaces, notably medium-density fiberboard (MDF).

Growing in market penetration

Powder paint systems were introduced more than 30 years ago. Since then, a growing number of product manufacturers have taken the step away from spraying liquid paint. Liquid has inherent challenges, including the need for very expert application in order to get a uniform coating without sagging or thin spots. Another is the ever-tightening requirements to reduce and capture volatile organic compound emissions from solvent carriers to comply with strict VOC air emission and occupational health rules.

Early adopters of the powder coating technique included manufacturers of appliances, HVAC equipment, 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. Expansion into new applications is feeding that growth.
