Abstract: A paint spray system includes a source of pressurized paint. At least a first and second spray gun are provided. Each spray gun has a gun inlet for receiving paint, a gun spray outlet for spraying paint on an article to be painted, and a gun bypass passage for passing through the gun an unused portion of paint. A feed conduit feeds paint from the source to the spray guns. A paint recycle conduit recycles unused paint from the paint spray guns. Each of the spray guns is separately adjustable for adjusting a rate at which paint is sprayed on an article independent of any adjustment of the other guns. The system is particularly adapted to spraying fast drying mixtures of a base paint and a catalyst.

Abstract: An electrostatic spray gun particularly adapted to the spraying of fast-drying paint mixtures while preventing the polymerization or setting up of the paint mixtures includes a gun body having defined therein a gun inlet for receiving paint, a gun spray orifice, an annular seat surrounding the orifice, and a supply passage communicating the gun inlet and the orifice. The gun also includes a valve assembly including a reciprocable valve member engageable with the valve seat to close the orifice and define a closed position of the valve member. The valve assembly further includes an electrode extending from the valve member through the orifice.
