Abstract
A single phase propellant solvent solution comprising dimethyl ether, water, water-soluble polar organic solvents, preferably mixtures of aliphatic alcohol and water-soluble polar organic slow drying coalescing solvent, is used to provide non-flammable aerosol water-based paint compositions. Water-solubilized oil-modified film-forming polymers are dissolved in the propellant-solvent solution and are readily dispersed from an aerosol container onto a substrate surface to form a water-resistant and durable film thereon upon air drying.
