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.
