General description

Conductive silver printing ink, resistivity 30-35 μΩ-cm, is a combination of polymer coated silver particles and silver-based compounds in an organic medium. It is a low cost conductive ink that can be printed on a variety of substrates like polyester, glass, and indium tin oxide (ITO) which can be cured at 150-180 °C.

Application

Conductive silver inks can be coated in between reduced graphene oxide (rGO) and copper surfaces to stabilize the charge carrying medium which can be used in the fabrication of a thermistor. Laser induced forward transfer (LIFT) may use conductive silver printing inks to print indium tin oxide nanoparticles based thin films for solar cells and organic light emitting diodes (OLEDS) based applications.
This Conductive Silver ink is an economical grade of specially formulated, screen-printable, conductive silver ink which provides good conductivity at low cure temperatures. This conductive silver ink provides low resistance of printed conducting tracks.

This Conductive Silver Printing Ink is comprised of a mixture of pure silver particles and organometallic silver compound in an organic medium. When printed on polyester (PET or PEN) films and then cured at 150 - 180°C, the particles consolidate to form a chemically-welded, continuous silver track to yield low bulk resistivity.
