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 Mn(III) complexes that are particularly suitable as replacements for organotin for sealant and RTV formulations. The Mn(III) complexes are comparable or superior to organotin such as DBTDL, superior to Mn(II) compounds, 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.
