    摘要: 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 system comprising the combination of a carboxylic acid, an amino-containing adhesion promoter or a mixture of amine-containing adhesion promoters and an amino-containing siloxane. The combination of these materials accelerates the condensation curing of moisture curable silicones/non-silicones even in the absence of a metal-based catalyst.

    摘要: The present invention provides curable compositions comprising non-tin metal catalysts that accelerate the condensation curing of moisture-curable silicones/non-silicones. In particular, the present composition employs a metal free catalyst system comprising a diazabicyclic compound as the catalyst. The diazabicyclic compounds exhibit catalytic activity comparable or superior to organotin such as DBTDL and exhibit certain behavior in the presence of components such as adhesion promoters that allow for tuning or adjusting the cure characteristics of the present compositions and provide good adhesion and storage stability.

    摘要: 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.
