  • Patent number: 8912294
    Abstract: Polyamines A1 of formula (I) or (II). They can be easily synthesized from readily available raw materials and have no primary amino groups or only a low content of primary amino groups and thus exhibit hardly any blushing. Their viscosity is relatively low, compared with polyamine/polyepoxide adducts of the polyamine on which polyamine A1 is based. Thus epoxy resin compositions can be formulated that are free of benzyl alcohol and free of blushing.
