A thermoplastic polymer, an acceptable, curable urethane poly alkylene polyol - prepolymer and a tackifier heat-resistant containing reactive hot-melt adhesive, for example, polyurethane and - - composition.
Hot melt adhesive compositions combining the characteristics of hot melt adhesives and reactive adhesives can be prepared by blending a thermoplastic polymer, having sufficient structural integrity to provide cohesive strength, with a urethane prepolymer and a tackifying agent. The composition has sufficient green strength to form initial bonds. Additionally, over time, the composition cures to a final rigid, resilient structural adhesive bond.
