A method and apparatus for applying a coating or paint such as a low-solids adhesion promoter onto a substrate such as a plastic part using an electrostatic process and a supercritical fluid such as CO2 is disclosed. Also disclosed is a spray gun that is desinged to have minimized coating leakages for use in connection with such a method. In one embodiment of the present invention, a paint spraying gun includes a gasket that seals the constituent parts of the gun that form a fluid flow path defined therein so that substantially no combustion or atomization of the fluid flowing therethrough occurs prior to exit from the guns spray tip. In this embodiment, the gun housing is designed to substantially reduce leaking of paint composition into the gun. It should be understood that the abstract of the disclosure is not intended to be and should not be found to be limiting to the scope of the claims contained in this application or in any patent issuing therefrom. |
