STABILIZATION OF NOBLE METAL CATALYSTS

Shelf life of noble metal catalyzed addition crosslinkable organosilicon compositions is remarkably increased by treatment of a noble metal catalyst having an oxidation state greater than 0 with a bidentate chelate compound. The latter may remain in the catalyst mixture or be removed, and the treatm...

Zusammenfassung:	Shelf life of noble metal catalyzed addition crosslinkable organosilicon compositions is remarkably increased by treatment of a noble metal catalyst having an oxidation state greater than 0 with a bidentate chelate compound. The latter may remain in the catalyst mixture or be removed, and the treatment may be performed in situ or ex situ with respect to the remainder of the crosslinkable composition components.
