Abstract
The present invention relates to a polyurethane composition consisting of a first and a second component, wherein the first component comprises an alkoxylated aromatic diol, a low molecular weight aliphatic or cycloaliphatic diol and a specific polybutadiene polyol in specific ratios. The cured composition is characterized by having good adhesive characteristics, a strength that is only slightly dependent upon the temperature in the temperature range of −35 to +85° C. and high strength and elasticity. It is particularly suitable as a structural adhesive for bonding two substrates.
