The present invention relates to an amine of the formula (I) which is an adduct of 1,2-propylenediamine with an aryl monoglycidyl ether, to the use thereof as part of a hardener for epoxy resins, and to epoxy resin compositions obtained therewith. The amine of the formula (I) is preparable in a simple process in high purity, is of very low viscosity and is especially suitable for the curing of epoxy resins. It allows low-emission epoxy resin compositions which have good workability and which cure even under cold and damp conditions, quickly and without blushing effects, to form very hard products of high surface quality that display virtually no yellowing on exposure to light.
本发明涉及一种化合物(I)的胺,该化合物是1,2-丙二胺与芳基单环氧丙基醚的加合物,其用作环氧树脂的硬化剂的一部分,以及由此获得的环氧树脂组合物。化合物(I)的胺可通过简单的方法制备,具有高纯度,粘度非常低,特别适用于环氧树脂的固化。它可以制备低排放的环氧树脂组合物,具有良好的加工性,在寒冷潮湿条件下甚至可以快速固化而不会出现发白效应,形成表面质量很高的非常坚硬的产品,在受光照射时几乎不会发黄。
