An amidine containing at least one structural unit of the formula (I) and the use thereof as catalyst for the crosslinking of a functional compound, especially of a polymer having silane groups. The amidine is preparable in a simple process from readily available starting materials, is largely odorless at room temperature and is of low toxicity. It accelerates the crosslinking of functional compounds surprisingly efficiently and can be adjusted for optimal compatibility with different compositions via the radical to which the structural units of the formula (I) is bonded, which means that such compositions do not have a tendency to migration-related defects such as separation, exudation or substrate soiling.
一种至少含有一个式(I)结构单元的脒,以及用它作为催化剂来交联功能化合物,特别是具有
硅烷基团的聚合物。这种脒可通过简单的工艺从容易获得的起始材料中制备,在室温下基本无臭,毒性低。它能以惊人的效率加速功能化合物的交联,并可通过与式(I)结构单元键合的基团进行调整,以实现与不同成分的最佳相容性,这意味着此类成分不会出现与迁移有关的缺陷,如分离、渗出或基底脏污。
