Patent ID: 8216682

Claim:
A moisture curable acrylic formulation comprising: a prepolymer consisting essentially of polyacrylic prepolymer as a major component by weight having an average molecular weight of between 3,000 and 600,000 grams per mole and between 2 and 6 inclusive moisture curable functional moieties of isocyanate per prepolymer, said curable functional moieties of isocyanate extending from a nonfunctionalized acrylic prepolymer backbone and adapted to moisture cure alone to form an acrylic polymer; a thermoplastic adhesive resin of ethylene vinyl acetate resin or polypropylene present at 10 to 40 total weight percent of the formulation; wherein said thermoplastic adhesive resin provide a shear strength to the formulation of at least 10 pounds per square inch when applied to a thickness of 0.75 millimeters between a glass substrate and a vinyl article 15 minutes after application at 120° Celsius in ambient atmospheric air and a silane molecule.
