Abstract
A method of electrostatically painting and an apparatus for producing an electric field within a booth includes a paint spray gun charged to a first potential and a target to be painted to a second potential with one of the panels in the booth charged to a third potential intermediate the first potential and the second potential to repel paint particles away from the panel. The paint particles and the panels are charged to the same polarity and the target is of the opposite polarity. The panel is usually a wall, a ceiling and/or a conveyor protection housing within the paint spray booth. The preferred panel comprises an outer insulating layer of plastic, glass or porcelain that is easily wiped of paint and an interior, electrically-conducting layer such as a thin sheet of aluminum. Variations of the panel include a version which is completely enclosed in plastic and a version which is bonded to plastic.
