摘要：
A two-part adhesive includes an A side, a B side, at least one of a polyurethane prepolymer and a diisocyanate, a polyol, a catalyst, and an adhesion promoter. The polyurethane prepolymer or diisocyanate is present in the A side from about 50% to 100% by weight of the A side composition. The polyol is present in the B side from about 52% to about 98% by weight of the B side composition. The catalyst is present in the B side from about 0.5% to about 5% by weight of the B side composition. The adhesion promoter is present in at least one of the A side composition and the B side composition from about 10% to about 50% by weight of the two-part adhesive. A ratio of isocyanate groups in the A side to hydroxyl groups in the B side is greater than 1.5:1.
