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.
将式 (I) 催化剂用于可固化组合物的交联。式(I)催化剂含有至少一个脂肪族
胍基。它在室温下基本无味且不挥发,能非常有效地加速可固化组合物的交联,同时不影响其储存稳定性。它特别适用于以含有
硅烷基团的聚合物为基础的组合物,具有非常好的相容性,因此,这类组合物不会出现催化剂分离、迁移或蒸发的趋势。
