OTech T is a unique silver particle-free conductive ink developed specially for the printing of silver layers with >80% transparency. It is ideal for printing of (flexible) transparent electronics like touchscreens, OLEDs or solar cells.OrelTech’s unique process allows the deposition of highly conductive thin metallic films. The thin layers undergo short development using cold plasma treatment resulting in a fine metal structure. OrelTech’s technology enables the deposition of the ink with many different methods and on various substrates, from plastics to fabrics. OTech inks do not contain nanoparticles, and as such enable the material economy of precious metals while being significantly more environmentally friendly than the existing alternatives on the market.Read an article on the OLED prototype constructed with OTech T published in Flexible and Printed Electronics: https://doi.org/10.1088/2058-8585/abe604

Curing Conditions
  • Curing time: 1-5 minutes.
  • Curing apparatus: Cold plasma instrument with a low pressure chamber.
  • Curing temperature: Temperature in the plasma chamber does not exceed 70 ⁰C. No additional heating is needed. That temperature can be lowered to room temperature using a temperature-controlled plasma chamber.

Directions for Use and Storage
  • Storage: Inks can be stored in closed containers for up to 12 month in dry, dark conditions.
  • Clean-up: Materials can be cleaned up using alcohols and ketones, preferably isopropanol.
  • Pre-treatment: In some cases, to ensure better wettability and/or adhesion, the substrate material must be pre-treated prior to ink application.
