About FLYCOND
FLYCOND inks print conductive and resistive layers on film and paper. Carbon and graphite inks form electrodes and resistive tracks; PTC inks form self-regulating heaters whose resistance rises with temperature, limiting their own power.
Typical properties of the range
| Property | Typical value | Method |
|---|---|---|
| Sheet resistance, CD-CB | 10–50 Ω/sq at 25 µm (target) | Four-point probe |
| Sheet resistance, CD-AG | ≤ 0.025 Ω/sq at 25 µm (target) | Four-point probe |
| PTC behaviour, CD-PT | Resistance rise with temperature declared per grade | Resistance–temperature curve |
| Viscosity at 25 °C | 10,000–30,000 mPa·s | Brookfield |
| Cure | 120–150 °C for 10–30 minutes | Box or tunnel oven |
Values for the FLYCOND range; the certificate of analysis for CD-PT gives the release values.
