Catalysts for room temperature vulcanisable (rtv) silicone compositions

Abstract

This relates to new cerium (IV) organometallic compounds, to methods for making said cerium (IV) organometallic compounds and to their uses as condensation catalysts e.g., for curing room temperature vulcanisable (RTV) silicone compositions comprising a polyorganosiloxane polymer having at least two hydroxy or hydrolysable groups per molecule, together with a suitable condensation curable cross-linker. Such compositions can include various additives and can be stored in one-part or multiple part compositions. This disclosure also relates to silicone elastomers and cured silicone sealants and/or adhesives prepared by curing said compositions using the cerium (IV) organometallic compounds as the catalysts.
