Abstract
The use of a catalyst of the formula (I) for the crosslinking of a curable composition. The catalyst of the formula (I) contains at least one aliphatic guanidine group. It is substantially odorless and nonvolatile at room temperature and accelerates the crosslinking of curable compositions very efficiently, without impairing the storage stability thereof. It is particularly suitable for compositions based on polymers containing silane groups, where it has very good compatibility, as a result of which such compositions do not have a tendency to separation or migration or evaporation of the catalyst.
