Metal coating conductive filler “TOYAL TecFiller™ TFM Series”


We can plate a uniform film of a metal such as silver or gold onto metallic, inorganic, or organic particles.
With the TFM Series, silver is plated onto the surface of various core materials.
This means that less silver is contained than when the conductive materials are made from silver itself, so it has the characteristic that migration is unlikely.


  • ・Uniform plating onto each individual particle is possible
  • ・Superior conductivity, oxidation resistance, moisture resistance, and inking characteristics
  • ・Plating of metals, ceramics, and organic matter is possible
  • ・Plating film variations: Au, Ag, Cu, Sn, etc.
