Abstract
Heat-curing, solvent-free one-component adhesives which are based on polyurethanes and which do not give off elimination products, and which are derived from A) a hardener component consisting of polyaddition products containing hydroxyl and uretdione groups, B) a binder component comprising 1,2-epoxide compounds having more than one 1,2-epoxide group and one or more hydroxyl groups in the molecule, C) catalysts for polymerizing epoxide groups, optionally D) further hydroxyl-containing compounds and optionally E) auxiliaries and additives known from adhesives technology; a process for preparing these compounds and to their use as heat-curing, one-component, solvent-free, thermally stable and solvent-resistant polyurethane (PU) adhesives which do not give off elimination products.
