  • Gasket containing fuel permeation barrier
    Patent number: 7574990
    Abstract: A method for reducing fuel permeation through gasketed joints in an internal combustion engine (10) includes surface treating the gaskets in a halogenated medium before placing them into service. A low-cost elastomer such as acrylic, EPDM or HNBR, can be used for the gasket body. The halogenated medium may comprise either a liquid bath or a gaseous bath, into which the gasket is immersed. The halogenated medium bath is excited by heating to accelerate the halogenation process. A gasket treated according to this invention possesses a chemically altered exterior surface which substantially enhances its fuel permeability resistance at relatively low cost.
    Type: Grant

  • Adhesive for bonding elastomers to metals
    Patent number: 6080268
    Abstract: Elastomers are securely bonded to metal substrates using an aqueous adhesive solution containing a silane adhesive in combination with a phosphonium quaternary salt additive. The additive concentration is preferably between 15% and 40% of the silane concentration. The concentration of the silane and additive in the water base is preferably 2.7%, on a weight basis.
