A method and system for powder coating non electrically conductive elements, preferably brake pads. A pre-treatment station is upstream of an electrostatic powder coating deposition station and a baking station for melting and polymerizing the powder coating in order to form a coating layer on a surface to be coated. The pre-treatment station 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 to be coated, in an amount aimed at producing a measurable weight increase in the non electrically conductive elements, which then causes them to conduct electrically. The water adsorbed and/or deposited is subsequently eliminated within the baking station.

An electrostatic spray device includes an electrostatic mixing chamber and an electrode pair in the electrostatic mixing chamber. The electrostatic mixing chamber receives an airflow that is driven by a fan of the electrostatic spray device. The electrostatic mixing chamber also receives a flow of fluid from a reservoir of the electrostatic spray device. The electrode pair is configured to apply electrostatic charge to droplets of the fluid suspended in the airflow. A voltage level of the electrostatic charge is adjustable responsive to a first DC output from a first DC convertor. A flow volume of the fluid from the reservoir is adjustable responsive to a second DC output from a second DC convertor. In some cases, a control unit of the electrostatic mixing device modifies the first or second DC outputs based on a target level of the voltage level or the flow volume.
