Abstract
Compositions which are stable when stored under anhydrous conditions, but when exposed to atmospheric moisture cross-link to form elastomers comprising (1) an organopolysiloxane having terminal condensable groups, (2) a silicon compound having at least 3 Si-bonded hydrolyzable groups per molecule and (3) from 30 to 100 percent by weight, based on the weight of the organopolysiloxane (1), of a powder obtained from the homopolymerization or copolymerization of an acrylonitrile in an aqueous medium.
Claims5
A composition which can be stored under anhydrous conditions but which cross-links to form an elastomer when exposed to moisture at room temperature, comprising ( 1) an organopolysiloxane having terminal condensable groups, (2) a silicon compound having at least 3 Si-bonded hydrolyzable groups per molecule and (3) from 30 to 100 percent by weight based on the weight of the organopolysiloxane (1) of a powder obtained from the polymerization of an acrylonitrile in an aqueous medium.
