Heat-curable epoxy resin composition having good reactivity/stability behaviour.

摘要

A heat-hardenable epoxy resin compsn. with (i) a polycarboxylic acid anhydride hardener and (ii) (opt. 1-4C alkyl-substd.) 1,4-diazabicyclo-(2,2,2)-octane(DABCO) as accelerator is characterised in that a part of the accelerator (ii) is replaced by a B halide/amine complex compsns. contg. accelerator (ii) and the complex opt. together with the anhydride hardener and/or a solvent are claimed per se.
