Abstract
Abstract An electrically conductive adherent film-forming adhesive which is rapidly curable thermally from a flowable liquid to an adherent and coherent solid at temperatures below about 120° C. and with a specific resistivity of less than about .001 ohm-cm. when cured, and comprising a uniform mixture with a formulation containing a liquid epoxy base resin, a hardening component for the epoxy resin consisting essentially of B·CF₃SO₃H, and silver metallic powder in an amount ranging from about 75% to 85%, with the powder having a substantial uniform particle size of less than about 20 microns (0.8 mil) in diameter.
