  • Method for producing a cross-linked siloxane network
    Patent number: 10654976
    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.

  • Adduct of an amine and a cyclic siloxane compound
    Patent number: 10155839
    Abstract: A composition comprises an adduct produced by reacting an amine compound and a cyclic siloxane compound. The amine compound comprises two or more amine groups independently selected from the group consisting of primary amine groups and secondary amine groups. The cyclic siloxane compound comprises two or more first siloxane moieties that contain cyclic ether moieties. An epoxy composition is made by reacting an epoxy resin and the composition comprising the adduct.
