ABSTRACT:
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 ##STR1## where R represents a divalent hydrocarbon radical, R.sup.1 represents the same or different monovalent hydrocarbon radicals, which can be substituted by an alkoxy group, and R.sup.2 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 alkoxy group via oxygen and to a hydrocarbon radical via carbon.
