In the industry of electronics, silver is one of the most widely applied conducting materials. And with the development of nanotechnology in the recent years, nano silver materials have penetrated into various fields especially in the printing ink manufacturing of touch display industry. Silver nano particles could fully absorb optic waves and appear black themselves, at the same time, they have scattering functions towards light. Silver paste or printing ink filled with nano silver materials has good performance in purity and density and could enhance imaging capability.

Silver nano particles have very good property of surface wettability and could adhere to the surface of other silver powders or pigment particles in the printing ink, improving lipophilic performance and wettability of Silver paste or printing ink, so that the dispersion matrix of the Silver paste or printing ink could be stable and printing performance could be improved. Due to its advantages of precision, tinting strength, adhesion, stability, low viscosity, and high conductivity, nano silver could be utilized to produce high quality inkjet printing ink and flexible printing ink, satisfying the requirements of large scale continuous automated production.
