Compositions which have a long shelf life in the absence of water, but crosslink in the presence of water at room temperature to form elastomers which are prepared by mixing (1) an organopolysiloxane containing condensable terminal groups with (2) an organosilicon compound containing at least three hydrolyzable groups per molecule which are bonded directly to silicon, (3) a condensation catalyst and, optionally, at least one additional substance, in which the condensation catalyst (3), is a reaction product obtained from the reaction of a finely divided, inorganic oxide with a reactive titanium compound.
