  • Patent number: 5419487
    Abstract: 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.

  • Patent number: 5374305
    Abstract: 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.

  • Patent number: 5171772
    Abstract: A coating of hydrophobic polymer is prepared by contacting a substrate with an aqueous media containing amphiphilic polymer and polymerizing polymerizable component to provide the hydrophobic polymer coating. The processes can be used to make stable dispersions of particles, such as pigments, for paint compositions.

  • Patent number: 5171613
    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.
