Abstract

Provided are methods of bonding a fluoroelastomer to a metal substrate; fluoropolymer compounds comprising a fluoroelastomer, a curing agent and a bonding promoter; and composite materials obtained by curing the compound. Further provided is the use of bonding promoters for increasing the bond strength between a fluoroelastomer and a metal substrate.
