  • Moisture curable organopolysiloxane compositions
    Patent number: 9493691
    Abstract: The present invention provides curable compositions that are substantially free of metal catalysts including both tin and non-tin metal catalysts. The curable compositions employ a catalyst composition comprising the combination of a (i) carbodiimide functional compound, and (ii) an amino-containing compound such as an amino silane functional compound and/or an organic amine compound. The combination of these materials, particularly when aged, accelerates the condensation curing of moisture curable silicones/non-silicones even in the absence of a metal-based catalyst.
    Type: Grant
    Filed: February 27, 2014
    Date of Patent: November 15, 2016
    Assignee: MOMENTIVE PERFORMANCE MATERIALS INC.
