ABSTRACT:
Electrostatic deposition of air atomized liquid coating materials by adjusting the conductivity of the coating material and the voltage applied thereto so that virtually no air ionization occurs. Thus, essentially all of the current reaching the object to be coated is carried by the sprayed material thus minimizing the charge build-up on the subject, and eliminating charge accumulation on ungrounded objects out of the spray zone.
