A chosen paint color and finish are mixed with solvents to process an electrical charge. The mixture is then administered through an air-pressurized spray gun that features a ground wire capable of producing a negative charge. A rotational bell located at the end of the gun’s nozzle ejects paint into the air through a spinning metal disc. This spinning metal disc (or bell) imparts an electrical charge to the coating particles. When the gun's trigger is pressed, the paint mixes with a compressed air stream to create a fine paint spray that's released through the gun. Through application, the atomized particles of the paint are electrically charged, repelling each other and spreading evenly as the particles exit the nozzle. Like a magnet, the static electricity draws the paint onto the grounded metal surface in a flawless coat.
Cleaning and preparation are important to the electrostatic painting process. Cleaning requires removing any foreign elements, such as tape and glue. The sanding, sandblasting, grinding, and stripping away of unwanted surface materials assures proper adhesion and smooth surfacing. Masking helps protect surrounding surfaces. Finally, surfaces are wiped down with solvents to remove and prevent oxidation.
