Abstract
The use of an amidine of formula (I) and/or a conversion product thereof as a catalyst for the crosslinking of a composition based on silane group-containing polymers. The amidine of formula (I) and the conversion products thereof are essentially odorless at room temperature and non-volatile and accelerate the crosslinking of the composition very well without impairing the storage stability of the composition, and are very compatible in the composition. As a result, the compositions do not have a tendency to separate, migrate or evaporate the catalyst.
