Abstract

Compositions which can be stored under anhydrous conditions but when exposed to moisture crosslink at room temperature to form elastomers, comprising a diorganopolysiloxane having terminal condensable groups, a silicon compound containing at least three hydrolyzable groups per molecule which are bonded to silicon, and an alkylenediamine in which at least one hydrogen atom that is bonded to a nitrogen atom of the alkylenediamine is substituted with a polyalkylene oxide.
