Nano-Silver Ink for Inkjet Printing

Silver Jet Ink

• Silver ink products for ink jetting such as Silverjet DGP and DGH series can easily produce electrode circuit with fine line width using jnk jet technology compared with Photolithography and can be well applied to materials for high functional electrode of various electrical parts because of excellent conductivity of silver nanoparticles. Silverjet DGP and DGH series are developed for low and high sintering temperature according to their purpose and showed excellent jetting property having compatibility with most of major commercial inkjet heads (Dimatix, Konica-Minolta, SEMCO) for a long time
