摘要： Use of isophoronediamine isomer mixtures containing more than 40%, preferably more than 50 up to 70%, of the trans-isomer and less than 60%, preferably less than 50 down to 30%, of the cis-isomer as reactant in polyaddition resins selected from epoxy, polyurethane and polyurea resins. As curing agents in epoxy resins compared with previously known isomer mixtures, the isomer mixtures containing more than 40% of the trans-isomer and less than 60% of the cis-isomer unexpectedly lead to an extended pot life with simultaneously reduced maximum curing temperature and therefore reduced shrinkage problems. The isomer mixtures are also surprisingly suitable as amine components with reduced reactivity for the chain extension of polyurethane/polyureas.
摘要翻译：使用含有多于40％，优选大于50％至70％的反式异构体和小于60％，优选小于50％至30％的顺式异构体作为反应剂的异构体异构体混合物选自环氧树脂，聚氨酯和聚脲树脂。作为环氧树脂中的固化剂与先前已知的异构体混合物相比，含有超过40％的反式异构体和小于60％的顺式异构体的异构体混合物意外地延长了适用期，同时降低了最大固化温度，因此减少收缩问题。异构体混合物也令人惊奇地适合作为聚氨酯/聚脲的链延长反应性降低的胺组分。
