ABSTRACT:
Crosslinkable compositions employing organosilicon compounds having at least two hydrolyzable groups, optionally a crosslinker, and optionally a compound containing basic nitrogen, include a crosslinking catalyst which is a reaction product of a phosphorus compound, a sulfur compound, and a tin compound. The compositions exhibit improved shelf life.
