ABSTRACT:
Water dispersible, one component, self crosslinkable poly(urethane-urea) composition that is stable and capable of curing at room temperature is prepared by forming a prepolymer comprising an alcoholized drying oil; a diisocyanate, a polyalkylene ether polyol, and a dihydroxy containing alkanoic acid polyol; neutralizing the prepolymer; contacting the neutralized prepolymer with water and diamine wherein the alcoholized drying oil has a sufficient content of monoglycerides to allow for chain extension in step (C) and the poly(urethane-urea) self-crosslinks upon drying. The waterborne poly(urethane-urea) composition exhibits good chemical resistance, adhesion, abrasion, and high gloss properties when used as a coating.
