Abstract

A two-component polyurethane adhesive is described. The polyurethane adhesive has high strength and extensibility, wherein the mechanical properties are only slightly dependent on the temperature. The polyurethane adhesive is suitable as a structural adhesive that is decomposed by heating in such a way that adhesive bonds can be undone in a temperature range of interest. The adhesive can include a triol, a diol, an alkoxylated aromatic diol, a polyamine, a polyisocyanate, and a polyurethane polymer having isocayanate groups in certain ratios.
