    摘要： A process for the electrostatic liquid spray application of coatings to a substrate is disclosed. The process comprises forming a liquid mixture in a closed system comprising at least one polymeric component capable of forming a coating on the substrate and a solvent component consisting essentially of supercritical carbon dioxide in at least an amount which when added to the polymeric component is sufficient to render the viscosity of the mixture to a point suitable for spray application. The liquid mixture is then sprayed onto a substrate to form a liquid coating by passing the mixture under pressure through an orifice into the environment of the substrate to form a liquid spray, while negatively electrically charging the liquid mixture by a high electrical voltage relative to the substrate and electric current by electrical discharge from at least one external electrode located near the orifice and close to the spray.

    摘要： The present invention relates to precursor adhesive coating compositions which optionally contain water, 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 adhesive coating composition onto a substrate to be coated. Processes for spraying these precursor adhesive coating compositions are also disclosed.
