Fluoroelastomer gasket compositions

The invention fluoroelastomer particulate, a curing agent and optionally a microsphere, the inert fine particles, and PTFE particles of the metallic oxide reducing agent and optionally mixed precursor elastomer is mixed gasket. According to one embodiment, the composition is applied to a substrate and cured to provide a fuel cell gasket. The mixture of the present invention provides a basis for the intended curing the mixture so as to have a distinct region of the inner joined by a cured elastomer.Gaskets, fluoroelastomer, the curing agent, cross-linked, particulate
