Application

This product is a conductive ink based on single-crystal copper nanoparticles in triethylene glycol monomethyl ether (TGME), is suitable for various digital printing technologies such as Inkjet and Aerosol systems. The ink offers high copper loading, low viscosity, reliable jetting with high open time, good printability, long shelf life, storage at room temperature (under Argon). Printed and laser sintered patterns provide low electrical resistivity and good adhesion to substrates.
