Product Data Sheet

Product Catalog Number: Sicrys™ IC25EG-1

General Information

Sicrys™ IC25EG-1, a conductive ink based on single-crystal copper nanoparticles in ethylene glycol (EG), is suitable for various digital printing technologies such as Inkjet and Aerosol systems. The ink offers long shelf life, storage at room temperature (under Argon), low viscosity and reliable jetting. Printed and laser sintered patterns provide low electrical resistivity and good adhesion to substrates. Applications include, but are not limited to, FPD, RFID and PCB.
