Conductive ink : Join the IoT revolution with innovative and flexible applications

SmartInk products are the right solutions for the printing of highly conductive and flexible circuits. SmartInk products are cured at low temperatures, enabling the use of flexible substrates (polyimide, PET, PEN…) and resulting in faster drying and lower sheet resistances than competitive silver products.

Functions :

ProtectInk S is the best choice for coating a protective layer on top of your printed circuits.
ProtectInk S ( P-ID21001) protects the silver coating against oxidation and scratches.

After coating ProtectInk S on top of Smart Screen F (nano silver conductive ink for screen-printing),
less than 3% resistance variation was observed after 1000h at 85%rH/85°C.
