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