Abstract:
The present disclosure relates to articles comprising first and second layers, each layer including a cross-linkable polymer and a cross-linker, to methods for preparing and curing such articles, and to articles formed thereby. In one aspect, the disclosure provides a curable article including a first layer including a first cross-linkable polymer comprising at least about two unsaturated carbon bonds, a first cross-linker comprising at least about two silicon-hydride functional groups, present in the first layer in an amount within the range of 0.1 wt. % to 20 wt. %, and a first hydrosilylation catalyst; and a second layer in contact with the first layer, the second layer comprising a second cross-linkable polymer comprising at least about two unsaturated carbon bonds, a second cross-linker comprising at least about two silicon-hydride functional groups, and a second hydrosilylation catalyst. The second layer does not include a substantial amount of the first cross-linkable polymer.
