Abstract:
A peelable foam coating composition, comprising a blend of:an aqueous polyurethane dispersion resin in an effective amount having at least 40 percent by weight solids contents; an effective amount of a release agent in an amount of from between 0.1 and 5 percent of the total weight percent of the composition, said release agent being selected from the group consisting of propylene glycol, soy lecithin, organosilicone fluids, nonylphenoxypoly-(ethyleneoxy) ethanol, oleic acid polyethylene glycol monostearate, petrolatum, sodium alkyl benzene, sulfonates, siloxanes, polyglycols, silicone surfactants, polyvinyl alcohol resins, paraffin and polymeric waxes, and synthetic waxes including low molecular weight polyethylene waxes, and combinations thereof; an effective amount of a propellant up to 25 percent by weight; a surfactant or profoamer in an effective amount of up to 5 percent by weight selected from the group consisting of alkanolamides, silicone glycols, alkyl benzene sulfonates, alcohol ethoxylated, phosphate esters, oleates, betaines, alkylphenol ether sulfates, alkylaryl sulfonates, fatty acids, soy lecithin, anionic, cationic, amphoteric, or nonionic surfactants, and combinations thereof; wherein upon curing said peelable foam coating composition forms a smooth sealed exterior skin enclosing a porous interior providing structural integrity thereto.
