Abstract

The invention relates to a polyurethane composition comprising one first component and one second component, said first component comprising an alkoxylated aromatic diol, a low molecular aliphatic or cycloaliphatic diol, a specific polybutadiene polyol and a specific polyetherpolyol, in specific ratios. The hardened composition is characterized by having good adhesion characteristics, a resistance which is only slightly dependent on the temperature, in the temperature range of −35 to +85° C. and also very high resistances. It is particularly suitable as a structural adhesive for bonding two substrates.
