Abstract: Aliphatic polyamines with methyl substituents are used in the curing of epoxy resins. The preparation of such aliphatic polyamines is described. Corresponding epoxy resin compositions include an epoxy resin and the aliphatic polyamines as curing agents. These curing agents combine comparably rapid curing at moderately elevated temperatures with comparably long pot life at room temperature. At the same time, they allow for cured epoxy resins with good mechanical properties and high glass transition temperature.
