ABSTRACT:
In accordance with the present invention, a blocked isocyanate composition which is useful as a curing agent for powder coatings is prepared from the reaction of tetramethylxylene diisocyanate and acetone oxime. In a preferred embodiment, a polyol is reacted with the isocyanate to provide a prepolymer with urethane linkages wherein the isocyanate groups of the prepolymer are substantially blocked with acetone oxime. The blocked isocyanate composition of the present invention can be used as a curing agent for powder coatings, adhesives and high solid coatings which are cured by baking. The blocked isocyanate composition of the invention can be used as a cross-linking agent for a hydroxy-containing polyester, a hydroxy-containing acrylic or methacrylic polymer or any other active hydrogen containing polymer.
