Abstract: An electrostatic powder spray coating method and apparatus for producing evenly coated continuous films of thermoplastic and thermosetting powders on substrates or parts having electrically conductive geometric complex surfaces and enables the use, without the occurrence of "cobwebbing," of significantly higher charging voltages for the spray gun in the spray coating of preheated substrates and parts, thus allowing faster coating lines. The invention features the use of a grounded electrically conductive ring for grounding the ionized field in the powder discharge region of the spray gun.

Abstract: Electrical conductors can be coated with a cured, thermosetting powder coating which, in its uncured state comprises a saturated, carboxyl group-containing polyester resin, an epoxy resin, an acrylic resin and, optionally, a cure catalyst, benzoin and/or a polyamide resin to provide insulative coatings with reduced air entrapment and improved dielectric strength.
