摘要：A two-component composition is described, comprising as component A) a one-component, moisture-curing silicone composition comprising a) at least one crosslinkable polydiorganosiloxane, b) at least one siloxane containing alkoxy groups as crosslinker, obtainable from the partial hydrolysis and condensation of one or more alkoxysilanes, at least one alkoxysilane being a trialkoxysilane or a tetraalkoxysilane, and the average degree of condensation of the siloxane containing alkoxy groups being at least 5, and c) at least one condensation catalyst, and as component B) an accelerator comprising water. The two-component composition makes a suitable adhesive or sealant. Addition of the aqueous accelerator to the silicone composition allows accelerated curing.
