General description

Highly conductive silver ink for Printed Electronics applications on flexible substrates. The low resistivity is resulting from the fusion of the metallic nanosilver particles during the sintering process.

Key Benefits

  • Low volume resistivity
  • Compatible with several sintering methods
  • Good adhesion on coated and synthetic papers, treated and untreated PET
  • Support for industrial print heads
  • High stability and easy handling

Typical Properties of Printed and Sintered Product

Single pass printed with KM1024i LHE on PowerCoat® HD1 and sintered with NIR lamp.
  • Resistivity <3 mW//25μm
  • Dry Film Thickness 1-2 μm
  • Printing resolution 150 μm lines & gaps
  • Adhesion 0-1 (ISO 2409 crosshatch test, no material removal)


Conductive nanosilver inks are made up of silver nanoparticle colloids and suspensions, which are majorly used in printed electronics. Their applications include flexible displays, printed circuit boards, solar cells, and disposable electronics.(3)


Basic Processing Guidelines

  • For prolonged shelf life, store between 0 and 4°C. Under typical jetting conditions, the ink will remain stable for one week.
  • Tested print heads are KM1024i LHE, Q-class Sapphire, DMC11610 (disposable cartridge)
  • Print head temperature between 25 and 35 ºC
  • Substrate temperature between 25 and 60 ºC
  • Sintering in ventilated box oven 150 ºC for 30 minutes. Higher sintering temperatures result in higher film conductivities and lower dwell times. Best results on paper have been obtained with NIR lamp
  • To avoid contamination from other inks before loading the print head with silver ink, it is recommended to flush with ethanol first, then flushing with the associated cleaning solution SI-JCS1, and then load the silver ink.

To clean the print head after use, proceed in reverse order.

The above printing and sintering conditions are guidelines. Conditions may vary based on customers′ experience and their application requirements, as well as customer printing and drying equipment.
