Tra-Con Inc. has released its tra-duct 2907 material, which is an electrically conducting silver-filled medium viscosity epoxy compound for electronic bonding and sealing applications.

The two-part, smooth paste formulation of refined pure silver and epoxy is free of solvents and copper or carbon additives. It develops strong, durable, electrically and thermally conducting bonds and coatings between many different and dissimilar materials such as metals, ceramics, glass and plastic laminates.

The product cures at room temperature and can be used as a "cold-solder" for heat-sensitive components where hot-soldering is impractical. It can also be used for the assembly and repair of electrical modules, PCBs, wave guides, flat cable, and high frequency shields. Viscosity (10rpm at 25C) is 6,500, thixotropic index (1rpm/10rpm) is 3.5, and pot life is 100 minutes.
