  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.

  Die vorliegende Erfindung betrifft die Verwendung eines Katalysatorsystems für die Vernetzung von Zusammensetzungen auf Basis von Silangruppen-haltigen Polymeren, umfassend einen Katalysator enthaltend mindestens eine aliphatische Amidin- oder Guanidin-Gruppe und einen Moderator in Form einer basischen Metallverbindung. Das Katalysatorsystem ermöglicht Zusammensetzungen auf Basis von Silangruppen-haltigen Polymeren mit einer schnellen, über die Lagerzeit stabilen Vernetzungsgeschwindigkeit, welche nicht zum Separieren oder Migrieren oder Verdampfen des Katalysators neigen und welche nicht empfindlich sind auf Störungen der Katalysatoraktivität durch übliche Füllstoffe oder Weichmacher.
