The present invention provides a curable composition comprising a non-tin metal accelerator that accelerates the moisture curable silicone / non-silicone condensation cure. In particular, the present invention provides accelerators comprising guanidine-containing compounds that are particularly suitable as organotin replacements in sealant and RTV formulations. Furthermore, compositions using guanidine-containing compounds are comparable or superior to organotins such as DBTDL, exhibit specific behavior in the presence of ingredients that allow the composition to be adjusted or adjusted, and have good adhesion. And provides storage stability. |
