Abstract: The present invention provides curable compositions comprising non-tin metal accelerators that accelerate the condensation curing of moisture-curable silicones/non-silicones. In particular, the present invention provides an accelerator comprising guanidine-containing compounds that are particularly suitable as replacements for organotin in sealant and RTV formulations. Further, the compositions employing a guanidine-containing compound is comparable or superior to organotin such as DBTDL, exhibits certain behavior in the presence of components that allow for tuning or adjusting the cure characteristics of the compositions, and provides good adhesion and storage stability.

Abstract: The present invention provides curable compositions comprising non-tin metal accelerators that accelerate the condensation curing of moisture-curable silicones/non- silicones. In particular, the present invention provides an accelerator comprising a biguanide compound that are particularly suitable as replacements for organotin in sealant and RTV formulations. Further, the compositions employing a biguanide compound are comparable or superior to organotin such as DBTDL, exhibits certain behavior in the presence of components that allow for tuning or adjusting the cure characteristics of the compositions, and provide good adhesion and storage stability.

Abstract translation: 本发明提供了包含非锡金属促进剂的可固化组合物，其加速湿气固化的硅氧烷/非硅氧烷的缩合固化。 特别地，本发明提供一种促进剂，其包含双胍化合物，其特别适合作为密封剂和RTV制剂中有机锡的替代物。 此外，采用双胍化合物的组合物与有机锡如DBTDL相当或优于组分，在组分存在下表现出某些行为，这些组分允许调节或调节组合物的固化特性，并提供良好的粘附性和储存稳定性。
