MOISTURE-CURABLE ADHESIVE COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a one-pack type moisture-curable urethane adhesive composition which finally exhibits excellent adhesion strength even if curing of the adhesive composition which had been coated on the portion difficult to come into contact with air (moisture) is retarded and, simultaneously, does not cause defects in the coated portions such as a failure in external appearance by uniformly and stably dispersing foams by a carbon dioxide gas to be generated at the time of moisture-curing into an adhesive layer. SOLUTION: This moisture-curable adhesive composition comprises 100 pts.wt. urethane prepolymer having isocyanate groups at both terminals to be obtained by reacting the terminal hydroxyl groups of a polyol with a polyfunctional isocyanate compound and 0.01-50 pts.wt. foam stabilizer. The foam stabilizer is a silicone type foam stabilizer and the polyol is a polyester polyol.
