Abstract: This application discloses dimethyl ether propelled water based aerosol compositions. Classes of aqueous thickeners are described herein which are suitable for use in aqueous aerosol coating compositions. The thickeners lose their thickening capability in the presence of dimethyl ether which is the aerosol propellant employed, and thus allows a low enough temporary viscosity to afford suitable flow and breakup when dispensed in spray form from an aerosol dispenser. On evaporation of the dimethyl ether during the spraying process, enough of the dimethyl ether is lost to allow the thickener to regain its thickening capability. High gloss, thick film, aerosol paints can thus be achieved.

Abstract: An aerosol container for dispensing thermo-setting polyurethane foam having an upstanding valve shell penetrating the top end of the container, a valve plunger disposed in the valve shell spring biased against an aperture in the top wall of the valve shell, a dip tube depending from the lower end of the valve shell toward the bottom of the container, and a resilient cap member detachably mounted to the top of the container wherein the cap member includes an upstanding dispensing nozzle having a downwardly depending conduit which depresses the valve plunger when the cap is depressed.The nozzle, valve shell, valve plunger and dip tube are fabricated from a low moisture content plastic such as polypropylene, polyethelene, or oxymethylene polyethers.

Abstract: This invention concerns sprayable, non-foaming emulsions of a film-forming polymer in water which are useful as aerosol paint sprays.

Abstract: This invention concerns sprayable emulsions of a foamable polymer in water which are useful as aerosol caulking or insulating compositions.

Abstract: This application discloses lechithin-based surface release compositions and aerosol containers containing surface release compositions, comprised of water, lecithin, dimethylether and optionally ethanol. The lecithin is dispersed in the aqueous phase of the composition, and an amount of dimethylether is employed as propellant sufficient to propel the lecithin from an aerosol container.

Abstract: A composition suitable for preparing a stable cellular foam, aerosol containers containing the composition, and methods of using the foamed composition to caulk and insulate, where the composition includes an emulsion of one or more foamable polymers and dispersed in the emulsion a foam forming amount of a mixture of a volatile organic liquid compound selected from the group consisting of a volatile hydrocarbon, a volatile halogenated hydrocarbon and mixtures thereof, and nitrous oxide, wherein the weight ratio of the organic liquid compound to nitrous oxide is selected such that the foam is self leveling and the volume of the foam is not greater than six times the volume of the composition.
