Abstract

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.
