Abstract
Nanosize titanium dioxide having supported thereon metallic platinum are efficient hydrosilylation catalysts whose hydrosilylation activity may be increased by irradiation. The catalysts are prepared by depositing soluble platinum compounds on a titanium dioxide sol or titanium dioxide pigments followed by drying, calcining, and reduction to platinum metal. The catalysts are particularly useful in preparing addition-curable organopolysiloxane elastomers.
