Abstract
Disclosed herein is a curable composition comprising a polyhydroxy curable fluoroelastomer, a polyhydroxy curative, a cure accelerator and an unsaturated metal compound process aid comprising a siloxane having at least one vinyl or allyl group bonded to a silicon atom. Such curable compositions have a lower Mooney viscosity than do similar compositions absent the process aid.
