Abstract
A two-component polyurethane composition including a polyol component and a polyisocyanate component, wherein the polyol component comprises at least one polyester polyol A1 based on dimer fatty acids and/or dimer fatty alcohols having an OH number of 65-350 mg KOH/g, at least one polybutadiene polyol A2 and at least one alkoxylated alkylenediamine A3. The polyurethane composition has high strength and only a minor dependence of the mechanical properties, especially strength, on temperature, especially in the range from −40° C. to +100° C.
