Room temperature crosslinkable compositions

Abstract From the Canadian patent

Abstract of the Disclosure, Compositions which are storable under anhydrous conditions, but when exposed to atmospheric moisture crosslink at room temperature to form elastomers comprising a diorganopolysiloxane having one Si-bonded hydroxyl group in each of its terminal units, and a cyclic silane of the formula , where R represents a divalent hydrocarbon radical R1 repre-, sents the same or different monovalent hydrocarbon radicals which can be substituted by an alkoxy group and R2 represents, hydrogen or an alkyl or aminoalkyl radical in which the silicon atom of the cyclic silane is bonded to a nitrogen atom and to two monovalent hydrocarbon radicals, which can be substituted with an …
