<p>The invention relates to humidity reactive hot melt adhesive compounds wh ich contain at least one isocynate group exhibiting polyurethane prepolymer, P1, which is liquid at room temperature, as well as at least one linear pol yurethane, P2, which is solid at room temperature and which contains polycap rolactone segments, exhibits hydroxyl groups, and exhibits a melting viscosi ty of 100-300 Pa.s at 170øC. The compounds are particularly characterized by an extended open time.</p> |
