Abstract

A two-component polyurethane adhesive is described having high strength and extensibility, wherein the mechanical properties are only slightly dependent on the temperature. The polyurethane adhesive can be suitable as a structural adhesive. The adhesive can include a triol, a diol, a polyamine, a polyisocyanate, and a polyurethane polymer having isocayanate groups in certain ratios.
