This invention provides conductive compositions that are directly solderable and that can be bonded directly to substrates. The compositions are made of silver exclusively in the form of flake and a resin system, said resin system comprising phenolic resin, acrylic resin, polyurethane resin, vinyl chloride/vinyl acetate copolymer, epoxy resin and epoxy hardner. By making a mixture of such a complex vehicle system a composition is produced that displays outstanding solderability and adhesion. Also provided is a method of making these compositions. |
