  • Click-reaction crosslinkable multicomponent silicone compositions
    Patent number: 8071708
    Abstract: Multicomponent silicone compositions which can be crosslinked via the click reaction and which, after mixing of the individual components, harden to give an elastomeric material contain: at least one compound (A) or (B), at least one compound (B) or (C), and at least one Cu catalyst (D), where (A) is an organic compound or an organosilicon compound which possesses at least two moieties having terminal aliphatic carbon-carbon triple bonds having terminally bonded hydrogen; (B) is an organic compound or an organosilicon compound which possesses at least two moieties having terminal aliphatic carbon-carbon triple bonds having terminally bonded hydrogen and simultaneously at least two moieties having carbon-bonded azide groups; (C) is an organic compound or an organosilicon compound which possesses at least two moieties having carbon-bonded azide groups.
