  The present invention relates to heat-curing epoxy resin compositions, which are characterized by high impact strength, good storage stability, and a low curing temperature. The epoxy resin compositions are suitable for use as a construction shell adhesive and for producing structural foams. They can already be cured in so-called bottom-baking conditions. Furthermore, it has been found that the use of an accelerator of the formula (Ia) or (Ib) results in an increase of the impact strength of heat-curing epoxy resin compositions.

  Silanes of formula (I): or inorganic fillers whose surface is coated or derivatized with a silane of formula (I), are curing agents for epoxy resins that are activatable at elevated temperature. The thermosetting epoxy resin compositions allow a large reduction in the curing temperature without great impairment of their storage stability. They are therefore very well suited for single-component thermosetting epoxy adhesives, which in particular may contain impact modifiers.

  式(I)的硅烷或表面被涂覆或衍生出式(I)的无机填料，是可在高温下活化的环氧树脂固化剂。这种热固性环氧树脂组合物可以在不大幅度损害其储存稳定性的情况下大幅降低固化温度。因此，它们非常适合于单组分热固性环氧粘合剂，特别是可能含有冲击改性剂。
