ABSTRACT:
An electrostatic liquid coatings application process and apparatus is provided in which supercritical fluids, such as supercritical carbon dioxide fluid, are used to reduce to application consistency viscous coatings compositions to allow for their application as liquid sprays. The coatings compositions are sprayed by passing the composition under pressure through an orifice into the environment of the substrate. The liquid spray is electrically charged by applying a high electrical voltage relative to the substrate and electric current.
