NuMetal-Copper is a copper metal, oxide­free ink which can be photonically or thermally sintered at low temperature (~150C) post­printing into a highly conductive metallic copper film. The product is designed to produce conductive traces on low temperature substrates. ZVNM­ 0009BE is specially formulated for compatibility and stability with higher­loading inkjet systems such as those from Dimatix.  This is currently a developmental product that is made to order for your application.
