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 catalyst system comprising an (alkyl)acrylic acid, a salt of an (alkyl)acrylic acid, or a mixture of two or more thereof. The (alkyl)acrylic acids or their salts exhibit catalytic activity comparable or superior to organotin such as dibutyltin dilaurate (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.
