Zusammenfassung:121 2 Special amine compositions comprising a) 30-70% by weight of a polyetherdiamine of the general formula (I) in which n is from 10 to 70, b) 3-30% by weight of a monoamine of the general formula R-NH, in which Ris the straight-chain or branched, saturated or preferably unsaturated radical of a hydrocarbon having 5 to 22 carbon atoms or of a monofunctional polyetheramine having a molecular weight of up to 400 g/mol and c) 3-30% by weight of a di- or triamine and d) 5-40% by weight of an alkylphenol of the general formula (II) in which Ris the straight-chain, branched or cyclic, saturated or unsaturated radical of a hydrocarbon having 5 to 14 carbon atoms, and curable epoxy resin compositions comprising these special amine compositions, the use of which results in thermosets which have a low degree of crosslinking, are resilient even at low temperatures and are resistant to chemical compositions, and the production of shaped articles and coatings using these curable compositions.
