  • Patent number: 9638325
    Abstract: A material for a gasket, wherein a chromate or non-chromate film, a phenol resin primer layer and a polyol-crosslinkable fluororubber layer are formed on one or both surfaces of a steel plate in this sequence from the side of the steel plate; the polyol-crosslinkable fluororubber layer is a rubber layer obtained by applying a fluororubber composition that comprises fluororubber, a polyol-based cross-linking agent, an amine-based cross-linking accelerator and silica to the phenol resin primer layer, followed by heating; and the amine-based cross-linking accelerator is a tertiary amine or a salt of a tertiary amine obtained by a reaction between a tertiary amine and an acid.

  • Patent number: 9193846
    Abstract: A gasket material including a steel plate and a foamed rubber layer formed on one or both sides of the steel plate, in which the foamed rubber layer is obtained from a rubber composition containing at least one of NBR, H-NBR or a functional group-modified NBR, as a rubber compound; and a crosslinking agent, and in which the foamed rubber layer has a quinoid crosslinking structure.
