  • Patent number: 4874548
    Abstract: An electrically conductive adhesive composition comprises an epoxy resin and stainless steel fibers, or other conductive fibers, having a length of about 4 mm to about 8 mm at a concentration of less 5% by weight. It is preferred that the stainless steel fibers have a length of about 6 mm and a diameter of about 2 .mu.m to about 20 .mu.m, and are present in a concentration of from about 0.7% by weight to about 1.5% by weight. The primary purpose of the adhesive is to continue conductivity across bonds in systems designed to prevent build-up and storage of static electrical charges.
