As explained by Products Finishing in their article “The Powder Coating Process,” powder coating is a dry finishing technique widely adopted for its efficiency and environmental benefits. This process involves applying a dry coating material composed of resin, pigment, and additives to a part. The material is electrostatically charged, adhering to the grounded part until melted and fused into a uniform coating in a curing oven.
Introduced over 40 years ago, powder coating has gained popularity, with over 5,000 finishers in North America using it for high-quality, durable finishes on various products. Notably, powder-coated finishes resist scratches, corrosion, abrasion, chemicals, and detergents. The process is not only cost-effective but also environmentally friendly, emitting minimal volatile organic compounds (VOCs) and requiring no venting or solvent recovery systems.
An additional advantage is the potential for reclaiming and reusing overspray, contributing to cost savings. The absence of air-drying or flash-off time, coupled with minimal reject rates, makes powder coating highly efficient. Moreover, it necessitates minimal operator training, offers ease of compliance with regulations, and ensures a clean working environment.
