  • System for dispensing of both water base and organic solvent base coatings
    Patent number: 5058812
    Abstract: An electrode (60) for electrically charging dispensed coating material is electrically substantially isolated from the coating material dispensing device (16). Sources provide first (30-36) and second (70-76) coating materials, the first (30-36) of which is electrically substantially more conductive and the second (70-76) of which is electrically substantially less conductive. The first (30-36) or the second (70-76) coating material is alternately supplied to the coating material dispensing device (16). A high-magnitude electrostatic potential supply (58) provides electrostatic high potential to the electrode (60) and selectively to the coating material dispensing device (16).
