Hot-melt adhesive compositions which are moisture-curable to a crosslinked urethane-urea polymer and which have high shear strength at elevated temperature, improved adhesion to substrates having low surface energies, improved heat resistance, and extended pot times. The compositions comprise a mixture of a polyisocyanate-reacted maleated polyolefin, optionally a polyisocyanate-reacted hydroxyl-containing material, and optionally a tackifying resin. |
