The invention relates to amidines containing at least one structural unit of formula (I) and their use as catalysts for the crosslinking of functional compounds, especially polymers containing silane groups. In a simple manner, the described amidines can be prepared from readily available raw materials that are virtually odorless and have low toxicity at room temperature. It surprisingly well and accelerates the cross-linking of functional compounds via radicals to which the structural units of formula (I) are attached and can be adjusted for optimum compatibility with different compositions, As a result, such compositions have a low tendency for migration-related defects such as separation, exudation or soil sticking by the substrate. |
