DuPont 7723 silver conductor is a screen printable, higher temperature fired-on composition containing lead-free glass frit as its binder. The glass allows high conductivity and adhesion to ceramic and glass substrates while providing a highly solderable surface. This material is printed using polyester or stainless screens with mesh counts ranging from 200 – 400tpi and processed at ~ 500°-540° C in an air atmosphere. It is widely used in the production of touchscreens, glass heaters and many other applications on glass and ceramic. It can be thinned with 8250 thinner.
