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)的醛缩胺可用作固化组分的潜在固化剂,例如,在具有
异氰酸酯基团的湿固化聚
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、
水解中和
水解后几乎没有醛味,且具有较长的货架寿命。在
水解过程中释放的聚
氨酯组合物中的醛仅具有轻微的软化作用,并且几乎没有迁移或渗出的倾向。
