The present invention relates to precursor coating compositions which are particularly suitable for being admixed with at least one supercritical fluid used as a viscosity reduction diluent and then spraying this resultant liquid mixture of supercritical fluid and precursor coating composition onto a substrate to be coated.

Precursor coating compositions suitable for spraying with supercritical

The present invention is directed to methods for spraying water-borne coating compositions having at least about thirty five percent by weight of the solvent fraction by using compressed fluids such as carbon dioxide and ethane, so as to decrease runs, sags and drying time in the application of coatings.

Methods for the spray application of water-borne coatings with

The present invention relates to precursor coating compositions containing water and at least one organic solvent which are particularly suitable for being admixed with at least one supercritical fluid used as a viscosity reduction diluent and then spraying this resultant liquid mixture of supercritical fluid and precursor coating composition onto a substrate to be coated. Processes for spraying this precursor mixture are also disclosed.

Precursor coating compositions containing water and an organic coupling

The present invention relates to polyesters which are particularly suitable in coating compositions which are sprayed with compressed fluids which act as viscosity reducing diluents.

Polyesters particularly suitable for use in coating compositions which

Methods are presented by which polymeric compositions, such as coating compositions, can be sprayed with compressed fluids, such as carbon dioxide, nitrous oxide, or ethane, at higher solids levels and with finer atomization to give improved spray application quality with reduced emission of solvent.

Method for spraying polymeric compositions with reduced solvent emission

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.
