Abstract: A silicone composition including: at least two reactive polydiorganosiloxane polymers P1 and P2 that together account for 20% to 60% by weight, based on the overall silicone composition; at least one crosslinker for polydiorganosiloxanes, with a proportion of 0.5% to 5% by weight, based on the overall silicone composition; at least one catalyst, with a proportion of 0.001% to 0.1% by weight, based on the overall silicone composition; at least one optionally hydrophobized filler, selected from precipitated or fumed silica and ground or precipitated chalk, with a proportion of 10% to 70% by weight, based on the overall silicone composition, wherein the reactive polyorganosiloxane polymer P1 has a higher reactivity in the condensation crosslinking with the crosslinker than the reactive polyorganosiloxane polymer P2 and the molar ratio P1:P2 in the composition is between 0.1 and 15.

Abstract: 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.
