Abstract
An electrostatic spray gun (10) for the spray application of electrically conductive materials includes a shield (24) to prevent the build-up of electrically conductive flash deposits on preselected non-conductive surface areas (26) of the gun (10). By prohibiting the build-up of electrically conductive flash on preselected areas of the gun surface, the shield (24) is effective in preventing the completion of an electrical circuit between a charged electrode (18) and an electrically grounded gun support member (22). The gun of the present invention is particularly effective in the high volume spray deposition of electrically conductive paints.
