Abstract
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.
