A curing agent for epoxy resin compositions containing at least one amine of formula (I) and at least one amine of formula (II). The curing agent is a low-odor, low-viscosity, low-toxicity curing agent and has a low propensity for carbamatization and a high reactivity toward epoxy resins. It enables low-odor and low-emission epoxy resin products which are readily processable and which even at low temperatures and high humidities undergo rapid and problem-free curing to afford high-quality plastics having a high hardness and a regular, non-tacky surface with high gloss.
