The present invention relates in a first consideration to aldimines of formula (I). Said aldimines are particularly suitable as latent hardeners in curable compositions, particularly compositions comprising one or two-component isocyanate groups. Due to the presence of the reactive group, they can be converted to compounds of the formulas (X) and (XII) comprising aldimine groups, implementing a further consideration of the present invention. The aldimines, or the compounds comprising aldimine groups, can be used primarily in adhesive and sealant materials, but also in coatings, and can be produced easily from readily available source materials, and have good thermal stability. The tertiary amino group thereof has a surprisingly low alkalinity and can in some cases have a catalytic effect in chemical reaction systems.
本发明涉及公式(I)的醛胺,首先考虑这些醛胺作为可固化组合物的潜在固化剂,特别是含有一种或两种异氰酸基团的组合物。由于具有反应性基团,它们可以转化为公式(X)和(XII)的化合物,包括醛胺基团,这是本发明的进一步考虑。这些醛胺或含有醛胺基团的化合物主要可用于粘合剂和密封材料,也可用于涂料,并且可以从易得的原料中轻松制备,并具有良好的热稳定性。其中的三级氨基具有惊人的低碱度,在某些情况下可以在化学反应系统中具有催化作用。
