Abstract: A method for admixing a solvent-borne compsn. contg. a high concn. of at least one solid polymer capable of being sprayed as a liq. soln. and at least one compressed fluid as a viscosity reducing diluent which is a ga at STP comprises admixing the solvent-borne compsn. and the compressed fluid together at a pressure P, the compressed fluid has a feed temp., T1, such that at least one compressed fluid is a gas or supercritical fluid and has a solubility parameter of 0.5-4 (cal/cc)1/2, thereby avoiding undesirable pptn. of the solid polymer and consequential plugging of the apparatus.

Abstract: A process which comprises (i) the generation of release surfaces by application to predetermined areas of a solid surface of a solution, suspension or dispersion of a release agent and a supercritical fluid that vaporizes from the release agent, (ii) the deposition of a mass onto the release surface containing the release agent, and (iii) the separation of the mass or a product derived from the mass from such surface covered by the release agent. Novel apparatus for carrying out the process are described.

Abstract: The present invention is directed to methods for spraying polymeric compositions with supercritical or subcritical compressed fluids such as carbon dioxide or ethane over a wider range of spray conditions to provide improved spray application quality with reduced emission of solvent. The methods are accomplished by using an elongated spray orifice to transform narrow, fishtail, liquid-film sprays to wider, feathered, decompressive sprays.

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.
