  A silane of the formula (I) containing at least one aliphatic amidine group- or guanidine group-containing alkoxy group, to a method for producing same, to conversion products thereof, and to the use thereof as a catalyst in curable compositions, in particular based on silane group-containing polymers. The silane of the formula (I) is largely odorless and non-volatile at room temperature. The silane accelerates the hydrolysis and condensation reaction of silane groups very effectively without impairing the storage stability of silane group-containing polymers. Additionally, the silane is very tolerable in silane group-containing compositions, whereby such compositions are not prone to separate, migrate, or evaporate the catalyst.

  The present invention provides strategies for making higher weight, cyclic polyamines from lower molecular weight, cyclic polyamine starting compounds via transamination. The higher molecular weight, cyclic polyamines are structurally similar to the lower molecular weight, cyclic polyamine starting compounds. The reactants used in the present invention include a cyclic polyamine component that comprises at least two amine groups separated from one another by at least a binary carbon atom spacing, and that can be transaminated to form a higher molecular weight, cyclic polyamine compound. The higher molecular weight, cyclic polyamine has at least two cyclic rings joined to one another through a nitrogen-containing hydrocarbyl group. Each of the cyclic rings contains two amine groups separated from one another by binary carbon atom spacing.

  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.
