  • Moisture curable organopolysiloxane composition
    Patent number: 9394443
    Abstract: The present invention provides curable compositions comprising non-Sn organo-metal catalysts that accelerate the condensation curing of moisture curable silicones/non-silicones. In particular, the present invention provides Fe(III) and Bi(III) complexes that are particularly suitable as replacements for organotin for sealant and RTV formulations. The Fe(III) and Bi(III) complexes are comparable or superior to organotin such as DBTDL and exhibit certain behavior in the presence of components that allow for tuning or adjusting the cure characteristics of the present compositions and provide good adhesion and storage stability.
    Type: Grant
    Filed: November 9, 2012
    Date of Patent: July 19, 2016
    Assignee: Momentive Performance Materials, Inc.
    Inventors: Sumi Dinkar, Mihirkumar Patel Maheshbai, Anantharaman Dhanabalan
  • MOISTURE CURABLE ORGANOPOLYSILOXANE COMPOSITION
    Publication number: 20140378612
    Abstract: The present invention provides curable compositions comprising non-Sn organo-metal catalysts that accelerate the condensation curing of moisture curable silicones/non-silicones. In particular, the present invention provides Zn(II) and Zr(IV) complexes that are particularly suitable as replacements for organotin for sealant and RTV formulations. The Zn(II) and Zr(IV) complexes are comparable or superior to organotin such as DBTDL and exhibit certain behavior in the presence of components that allow for tuning or adjusting the cure characteristics of the present compositions and provide good adhesion and storage stability.
