ABSTRACT:
A silicone composition which is stable in the absence of moisture, but cures to an elastomer upon exposure to moisture consists essentially of a hydroxyl endblocked polydiorganosiloxane; a difunctionalsilane having acetamido, urea, or urethane functional groups; and a tetrafunctionalsilane having oximino functional groups. A composition containing 100 parts by weight of the polydiorganosiloxane, from 0.1 to 7 parts by weight of difunctionalsilane, from 0.1 to 7 parts by weight of tetrafunctionalsilane, and a ratio of difunctionalsilane to tetrafunctionalsilane of from 0.1 to 3, and optional filler is useful as a sealant or adhesive, having an improved skin over time.
