  • Compositions comprising siloxane compounds and methods for using the same
    Patent number: 10246558
    Abstract: 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.
    Type: Grant
    Filed: May 16, 2017
    Date of Patent: April 2, 2019
    Assignee: Milliken & Company
    Inventors: Sudhanshu Srivastava, Sasha Stankovich, Michael E. Wilson, Robbie W. J. Hanssen, Eduardo Torres, Cliferson Thivierge, Russell A. Stapleton, Eric B. Monroe

  • METHOD FOR PRODUCING A CROSS-LINKED SILOXANE NETWORK
    Publication number: 20170335064
    Abstract: A method for producing a cross-linked siloxane network comprises the steps of: (a) providing a first part comprising a first siloxane compound and a cure inhibitor, (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 with each other to produce a cross-linked siloxane network.
