Powder Coating is a dry finishing process that has become extremely popular since its introduction in North America in the 1960's. Powder coatings are based on polymer resin systems, combined with curatives, pigments, leveling agents, flow modifiers and other additives. These ingredients are melted, cooled, and ground into a uniform powder. A process called electrostatic spray deposition is used to achieve the application of the powder to a metal substrate. This application uses a spray gun, which applies an electrostatic charge to the powder particles, which are attracted to the grounded part. After the powder application, the parts enter a curing oven where, with the addition of heat, the coating chemically reacts to produce long molecular chains, resulting in high cross-link density. These molecular chains are very resistant to breakdown.
Powder coating is a high-quality finish found on thousands of products you come in contact with daily. It protects the toughest machinery, as well as household items you depend on each day. It provides a more durable finish than liquid paints can offer, while providing an attractive finish. Powder coating finishes are more resistant to scratches, chipping, abrasions, corrosion, fading and other wear issues. In addition to powder coating being tough it is an attractive choice due to environmental advantages. Powder coating contains no solvents and therefore emits negligible, if any, polluting VOC's into the atmosphere.
