Description

The use of powder coating as a finishing process has grown significantly in the past several years. More and more companies have turned to powder coating as a way to produce a high-quality finish while increasing production rates, cutting costs, and complying with increasing environmental pressures. Liquid finishing requires the use of solvents to convey the resinous binder over a surface. These liquid solvents necessitate venting, filtering, and solvent recovery systems to control volatile organic compounds (VOC). Powder coating, on the other hand, is a dry finish, which does not use VOC during any part of the finishing operation. The excellence of the powder-coated finish when compared to liquid coating systems is accompanied by substantial cost savings. There are savings in labor costs because less training is required to operate a powder coating system. There is no mixing of powder with solvents or catalysts. Maintenance costs are also low, as most clean-ups can be done with a vacuum. Powders used for powder coatings are solids and most are classified as nonhazardous. This manual will assist you in understanding the process, materials, and application methods of this ever-growing finishing technology.
