HEAT-CURING, ONE-COMPONENT ADHESIVES WHICH ARE BASED ON POLYURETHANES, A PROCESS FOR THEIR PREPARATION, AND THEIR USE

摘要

Disclosed is a heat-curing one-component compositioncomprisingA) as a hardener component, a polyaddition productcontaining hydroxyl and uretdione groups,B) as a binder component, a 1,2-epoxide compound havingmore than one 1,2-epoxide group and one or more hydroxylgroups in the molecule, andoptionallyC) a further hydroxyl-containing compound. Thecomposition is useful as an adhesive for a heat-resistantsubstrate and does not give off elimination products.
