RAL DESCRIPTION This is a method of applying electrostatically at omized coating material The No 2 Electric Pro cess Handgun system applies a high voltage DC negative charge to the applicator bell creat ing an electrostatic field between the bell and the target object The target is electrically grounded through its support which may be stationary or moving or through an electrical connection to a known earth ground A regulated pressure fluid system delivers coating material to the electric motor driven bell when the gun is triggered There the fluid travels across the face of the rotating bell and is charged The fluid is atomized at the edge of the bell forming a fine mist which under the influence of the electrostatic field is attracted to and deposited on the target object The forces between the charged particles and the grounded target are sufficient to turn most normal over spray around and deposit it on the rear surface of the target Therefore most of the spray is de posited and overspray is controlled This pro cess makes the No 2 Electric Process Handgun one of the most efficient electrostatic spray prod ucts on the market The No 2 Electric Process Handgun applies a DC negative charge to the coating materials at the point of atomization The electrostatic charge allows a more efficient uniform applica tion of coating material to the front edges sides and back of products making it highly suitable for a
