Aldimines of Formula (I), which can be used as latent curing agents in curing compositions, for example, in moisture-curing polyurethane compositions that have isocyanate groups. The aldimines are compounds that can be liquid at room temperature, can have a hardly noticeable aldehyde odor before, during and after hydrolysis, and can have a long shelf life. An aldehyde in polyurethane compositions that is released during hydrolysis has only a slight softening effect and can exhibit very little tendency to migrate or exude.
式(I)的醛缩胺可以用作固化组合物中的潜在固化剂,例如在具有
异氰酸酯基团的湿气固化聚
氨酯组合物中。这些醛缩胺化合物可以在室温下为液体,
水解前、期间和后几乎没有
醛类气味,并且可以具有很长的货架寿命。在
水解期间释放的聚
氨酯组合物中的醛仅具有轻微的软化效果,并且可以表现出极少的迁移或渗出倾向。
