Abstract

Room temperature curable compositions, which can be stored under anhydrous conditions, but when exposed to atmospheric moisture at room temperature cure to an elastomer comprising a diorganopolysiloxane having terminal condensable groups, a silicon compound containing acetoxy, tert-butoxy and SiC-bonded alkyl groups and a condensation catalyst, if desired, in which at least a portion of the silicon compound containing acetoxy, tert-butoxy and SiC-bonded alkyl groups is obtained from the reaction of an alkyltriacetoxysilane and tert-butanol in aqueous acetic acid.
