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.
