Abstract
This invention concerns sprayable, non-foaming emulsions of a film-forming polymer in water which are useful as aerosol paint sprays.
Claims19
A composition suitable for dispensing from an aerosol container by the action of dimethyl ether propellant comprising an aqueous emulsion of a film-forming polymer, and a propellant amount of dimethyl ether, wherein the film-forming polymer is emulsified by a nonionic surfactant having an HLB value of at least about 14, and said composition when dispensed from an aerosol container provides a smooth and foam-free film on the substrate to which it is applied.
An aerosol dispenser containing therein a dispensable composition comprising a film-forming polymer emulsified in an aqueous solution of dimethyl ether, wherein said film-forming polymer is emulsified by a nonionic surfactant having an HLB value of at least about 14 or above, and said emulsion being under dimethyl ether gas propellant pressure in said dispenser sufficient to propel said emulsion from said dispenser and onto the surface of a substrate to provide a smooth and foam-free film on the substrate to which it is applied.
