Fast curing fluoroelastomeric compositions, adhesive fluoroelastomeric compositions and methods for bonding fluoroelastomeric compositions

摘要

Compositions including at least one curable fluoropolymer are disclosed which include at least one functional group for crosslinking the fluoropolymer, a curative capable of crosslinking the at least one fluoropolymer selected from the group consisting of functionalized biphenyl-based compounds, various monoamidine and monoamidoxime compounds as well as bisamidine compounds and combinations thereof; and at least one cure accelerator which may be an organic peroxide or an organic peroxide in combination with a colorant. Adhesive fluoroelastomeric compositions comprising colorants are also provided. The compositions described provide beneficial physical properties, increased plasma resistance, unique adhesive properties and/or reduced contamination associated with use of external adhesives. Methods for forming articles which incorporate fluoroelastomers bonded to metallic surfaces are also provided.
