Zusammenfassung:	Heat-curing epoxy resin compositions containing a curing agent in the form of a mixture of aromatic dicarboxylic dihydrazide with a dihydrazide chosen from the group consisting of glutaric dihydrazide, adipic dihydrazide, pimelic dihydrazide, 8,12-eicosadienedioic acid-1,20-dihydrazide and 4-isopropyl-2,5-dioxoimidazolidine-1,3-di(propionohydrazide). The epoxy resin compositions are particularly suitable for automotive body-in-white bonding, where after induction pre-curing without additional metal joining techniques the pre-cured adhesives are cured again in a further step at temperatures of around 180° C.
