摘要:
A heat-curing epoxy resin composition that includes an epoxy resin, a curing agent, an accelerator, and an optional toughener. The epoxy resin compositions are suitable in particular for use as bodyshell adhesives and for preparation of structural foams. An accelerator of formula (I) results in increased impact strength the of heat-curing epoxy resin compositions.
