Abstract
A method for producing a cross-linked siloxane network comprises the steps of: (a) providing a first part comprising (i) a first siloxane compound comprising at least one cyclic siloxane moiety and (ii) a second siloxane compound comprising a plurality of siloxane moieties, (b) providing a second part, the second part comprising a hydroxide salt, (c) combining the first part and the second part to produce a reaction mixture, (d) heating the reaction mixture to a temperature sufficient for the hydroxide salt to open the ring of the cyclic siloxane moiety, and (e) maintaining the reaction mixture at an elevated temperature so that at least a portion of the opened cyclic siloxane moieties react to produce a cross-linked siloxane network.
