Method and system (1) for powder coating non electrically conductive elements (2), preferably brake pads, wherein upstream of an electrostatic powder coating (5) deposition station (4) and a baking station (6) for melting and polymerizing the powder coating in order to form a coating layer (9) on a surface to be coated, there is a pre-treatment station (3) which causes the elements to be coated to conduct electrically by uniformly wetting said elements by means of creating poorly mineralized water covalent bonds on at least one surface (8) to be coated, in an amount aimed at producing a measurable weight increase in the non electrically conductive elements (2), which then causes them to conduct electrically; the water adsorbed and/or deposited is subsequently eliminated within baking station (6). |
