Abstract: This invention is directed to improved spraying apparatus for coating substrates with a coating material and supercritical fluid which apparatus is provided with various features, either alone or in combination, to prevent undesirable premature cooling of the coating mixture which might detrimentally affect the final coating on the substrate; to prevent undesirable depressurization of supercritical fluid contained in the coating mixture which remains in the spray gun after spraying has been stopped; and/or to desirably provide the ability to mix the components of the coating mixture directly in the spray gun. Methods for utilizing these features in the spraying apparatus of the present invention are also disclosed.
