Abstract

See full text

The present invention relates to a two-component polyurethane adhesive consisting of a polyol component and a polyisocyanate component, wherein the polyol component comprises a triol with a molar mass of 1,000 to 10,000 g/mol, a diol having two primary hydroxy groups and a molar mass of 60 to 150 g/mol, a poly(trimethylene oxide) diol or a poly(tetramethylene oxide) diol with a molar mass of 200 to 3,000 g/mol and an aliphatic polyamine. The adhesive is characterized by high early strength, a low temperature dependence of the mechanical properties, good adhesion and the possibility of controlled thermally induced release of adhesion.
