Attorney, Agent or FirmInternational ClassesH05K 009/00H01S 004/00 AbstractA conductive gasket for sealing facing flange plates against passage of electromagnetic and environmental effets has a conductive sheath, for example supported on a molded, resilient foam core, and structure for affixing the seal to conductive elements to be sealed. A conductive coating having suspended conductive particles in a nonreactive binder is applied externally to the sheath in order to reduce galvanic corrosion by isolating the dissimilar metals contained in the sealed elements and in the conductive sheath. The sheath coating is preferably applied as a colloidal suspension of carbon particles, to the entire outer surface of a metal plated sheath and provides a low resistance, environmentally isolated junction between the sheath and the elements to be sealed, excluding environmental electrolytes, while improving abrasion resistance and flame retardant attributes of the seal.Field of SearchElectrical device making | |
