Our coating system is electrostatic powder coating. The object to be coated must be given a positive charge by means of rectified high voltage so that an electrical field can be built up.
Negative-charged particles are shot out of the pistol and travel along the electrical field lines towards the part. They are deposited on the surface and adhere to it because of the positive charge in the surface.
The application of heat causes the particles to fuse together like an enamel paint coating. Coating powder can meet all requirements: colour, gloss, mechanical or chemical exposure, or resistance to corrosion or the weather.
