Abstract

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 invention provides bismuth(III) sulfonate complexes that are particularly suitable as replacements for organotin in sealant and RTV formulations. In one embodiment, the present invention provides bismuth (III) camphorsulfonate and bismuth(III) methanesulfonate complexes. Further, these bismuth(III) sulfonate complexes are comparable or superior to organotin such as DBTDL, 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.
