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.
含有至少一个式(I)结构单元的
胍类化合物及其作为交联功能化合物的催化剂的用途,特别是用于具有
硅烷基团的聚合物的交联。该
胍类化合物可以从易得的起始材料中简单制备,室温下几乎无气味且毒性低。它能够出人意料地高效加速功能化合物的交联,并且可以通过式(I)结构单元所连接的自由基来调整其与不同组分的最佳兼容性,这意味着这些组分不会存在迁移相关的缺陷,如分离、渗出或基底污染。
