Abstract
A compound containing at least one hexahydrotriazine unit of formula (I) having at least one amidine or guanidine group and to the use thereof as a catalyst for the crosslinking of a functional compound, in particular a polymer including silane groups. The compound contains at least one hexahydrotriazine unit of formula (I) is producible in a simple process from readily available feedstocks, odorless at room temperature, non-volatile and largely non-toxic. The compound accelerates the crosslinking of functional polymers surprisingly well and by simple variation of the substituents is variable such that it has very good compatibility in different polymers as a result of which such compositions do not have a propensity for migration-based defects such as separation, exudation or substrate contamination.
