A composition comprises a first siloxane compound comprising at least one cyclic siloxane moiety and a first salt, the first salt comprising a conjugate base of a volatile organic acid. A method for producing a cross-linked siloxane network comprises the steps of providing a first siloxane compound comprising at least one cyclic siloxane moiety, providing a first salt comprising a conjugate base of a volatile organic acid, combining the first siloxane compound and the first salt to produce a reaction mixture, heating the reaction mixture to a temperature sufficient for the first salt to open the ring of the cyclic siloxane moiety, and maintaining the reaction mixture at an elevated temperature so that at least a portion of the opened cyclic siloxane moieties react with each other to produce a cross-linked siloxane network.
