Dupont announced new silver conductive inks for printed electronics, which can be used for OLEDs and touch screens. The new screen printable inks include: DuPont 7723, a low temperature firing silver ink suitable for printing on glass, and DuPont 9169, a low temperature curing Ag ink designed for flexible substrates.
The 7723 ink delivers excellent adhesion to Indium Tin Oxide (ITO) coated glass, it is lead-free and solderable, ideal for use in Touch Screen devices. The 9169 has extremely high conductivity, strong adhesion to ITO coated flexible substrates, low contact resistance to ITO, and fine line capability. Both products are recommended where high performance on coated substrates is critical, such as in Touch Screens and OLEDs.
