ABSTRACT:
The processibility of high viscosity, marginally extrudable polyorganosiloxane compositions containing a reinforcing silica filler and a filler treating agent to prevent crepe hardening of the compositions is improved by the presence in said treating agent of at least one component that is incompatible with the polydimethylsiloxane portion of the curable composition prior to the reaction of said component with the filler.
