Patent ID: 7576164

Claim:
An article comprising: A) a metal substrate; and B) a fluoroelastomer composition adhered to said metal substrate, said fluoroelastomer composition comprising i) a fluoroelastomer comprising 1) 35 to 75 mole percent copolymerized units of tetrafluoroethylene; 2) 20 to 60 mole percent copolymerized units of propylene; 3) 0.05 to 12 mole percent copolymerized units of a first cure site selected from the group consisting of trifluoroethylene; 3,3,3-trifluoropropene-1; 1,2,3,3,3-pentafluoropropylene; 1,1,3,3,3-pentafluoropropylene; and 2,3,3,3-tetrafluoropropene; and 4) 0.05 to 4 mole percent of a second cure site selected from the group consisting of a) copolymerized units of a brominated cure site monomer, b) copolymerized units of an iodinated cure site monomer, c) copolymerized units of a chlorinated cure site monomer, d) brominated endgroups, e) iodinated endgroups and f) a combination of any of a)-e); ii) 0.1 to 20 parts by weight per 100 parts fluoroelastomer of a polyhydroxy curing agent; iii) 1 to 30 parts by weight per 100 parts fluoroelastomer of an acid acceptor; and iv) 0.1 to 20 parts by weight per 100 parts fluoroelastomer of a vulcanization accelerator.
