A conversion product which has at least one aliphatic amidine or guanidine group and at least one polysiloxane radical, and the use of the conversion product as a catalyst for cross-linking hardenable compositions, in particular based on polymers containing silane groups. The conversion product is largely odor-free, non-volatile, and of low toxicity. The conversion product accelerates the cross-linking of such compositions surprisingly well, does not impair the stability of such compositions in storage, and is very highly compatible, which means that such compositions do not tend toward separation or migration or evaporation of the catalyst.
一种具有至少一个脂肪族脒基或胍基和至少一个聚硅氧烷基的转化产物,以及将该转化产物用作交联可硬化组合物的催化剂,特别是基于含有硅烷基团的聚合物。该转化产物基本无气味、不挥发、毒性低。该转化产物能出人意料地加速此类组合物的交联,不会损害此类组合物在储存过程中的稳定性,而且相容性非常高,这意味着此类组合物不会出现分离、迁移或催化剂蒸发的趋势。
