15 Years experience in powder coating manufacturing and practical application

More than two decades after their frist start the thermosetting powder coatings became in 1985 a technically viable product and a commercial success. Powder coatings are 100% dry paints that contain no solvents. They are generally applied to metal substrates by means of electrostatic spray equipment that provides each powder particle with a small electric charge, which in turn makes it stick to the substrate. The coated objects then go into a high temperature oven (usualy 150 to 200°C), where the powder coating melts and reacts chemically while sintering together to a continuous smooth finish of a thermoset film.
