XZ250 – Thermal Flexible Conductive Silver PTF for High Speed
XZ250 is flexible conductive silver PTF (Polymer Thick Film). Developed for application by flat bed screen but also
compatible rotary screen (with field trials on gravure on-Going).
The ink is thermally dried to give a tough, highly-conductive film. The cured film also has excellent flex
Typical surface resistivity at a dry film print thickness of 25µm is ≤0.012 Ω/sq
*It should be noted that by altering the print thickness of the ink the resistance value can be changed.
XZ250 can additionally be mixed with conductive carbon ink 26-8203 to produce intermediate resistance values and additionally reduce cost.
In addition to printing trace/circuitry this ink can also be used for printing large blocks areas for applications such as
RF shielding layers. XZ250 is suitable for use on most common flexible and rigid substrates.

XZ352 - F LEXO GRAPHITE CONDUCTIVE INK FOR RFID
XZ352 has been specially formulated for application by the flexographic printing process, suitable for use with
normal rubber and photopolymer stereos. It is an aqueous based graphite conductive ink for the economic
production of RFID antennas. It is suitable for high-speed flexo printing on a wide range of substrates giving
excellent adhesion and flexibility on treated polyester and paper. This ink is a single component system for ease
of use, no mixing of a hardener component is required. The ink has a long shelf life & good working life during
the printing process.
Conductive component is carbon graphite - to offer good conductivity at a lower price than silver (or other metal)
based conductive inks.
SHEET RESISTIVITY < 40.0 Ω / sq. at 10microns dry film thickness
SOLIDS CONTENT 47-51.0%
VISCOSITY 25-30 poise at 25oC
DRYING < 1 minute @ 100 oC
40 ohms/sq. can be achieved on a non-absorbent polyester substrate at dry film thickness of 10 microns. A higher
figure is likely on absorbent substrate and therefore two workings may be required to meet a particular
If lower graphite content is required then this can be achieved with addition of Water Based Flexo Medium (Please
contact Coates for details).
