For electrostatic coating, VESTOSINT
powder is electrostatically charged as it exits a powder gun and sticks to the grounded metallic piece to be coated. The piece is then heated to a temperature above the melting point of the powder (approximately 176°C), causing the powder to fuse into a smooth, non-porous plastic film.
Electrostatic coating is an environmentally friendly method of surface finishing because the entire coating process is executed solvent-free and creates no toxic substances.
In contrast to coating with thermosets, VESTOSINT
polyamide 12 powders do not crosslink, and the coating retains its thermoplastic character.
