Powder coatings have been developing as an environmentally acceptable finishing method since the mid-1950s. These coatings are essentially dry paints. They are coatings that are formulated with the same resins, pigments, and additives as paints, but without solvents. Solvents are used in paints simply as a vehicle to transport the resins and pigments to the piece that will be finished and then evaporated from the film. By eliminating the solvents, we dramatically reduce organic emission to the atmosphere and virtually eliminate effluent discharge from the factory.
