  • Galvanically compatible conductive filler and methods of making same
    Patent number: 5750249
    Abstract: Composite particles suitable as conductive filler for electrically conductive compositions which can be used as gaskets, caulking and plastics, for example. The compositions are, useful as EMI shielding and electrostatic charge dissipation materials. Methods of making and using the foregoing are also covered.
    Type: Grant
    Filed: February 5, 1993
    Date of Patent: May 12, 1998
    Assignee: Potters Industries, Inc.

  • Galvanically compatible conductive filler useful for electromagnetic shielding and corrosion protection
    Patent number: 5286416
    Abstract: Composite particles designed as a filler for gaskets, caulking compounds and plastics in general. The unique properties are obtained by using a soft metal core galvanically similar to the metal the sealant will be in contact with. The oxide surface of the core metal is typically breached by a multitude of small hard semiconductive or conductive particles, thus making low particle-to-particle contact resistance through the body.
