    摘要： 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.

    摘要： The invention relates to organopolysiloxane compositions which are stable when stored under anhydrous conditions, but when exposed to moisture cure to an elastomer containing (a) a diorganopolysiloxane having terminal condensable groups, (b) a silicon compound having 3 amino groups bonded to silicon via nitrogen and/or oxime groups bonded to silicon via oxygen per molecule and (c) a silicon compound having at least one thiol group selected from mercapto-functional silanes or siloxanes. The presence of the mercapto-functional silanes or siloxanes substantially retards the formation of skin but does not substantially extend the cure time of the organopolysiloxanes compositions. These compositions are useful in, for example, screen printing, where a long skin-over time is desired.
