JELCON CH­8 is carbon paste of one­component polymer type designed for membrane switches and flexible printed circuits. The resistance is low and makes it possible to improve the performances of the printed matter as well as to save the cost.

1. Low resistance. 10.0 ohm/cm², thickness : 14 microns
2. Low price with good cost-performance.
3. Good adhesion to (untreated) PET film.
4. Excellent flexibility.
5. Good stability due to one component type. Good printability.
6. Compatible with other makers’ silver paste.

2. Viscosity : 23500-36500 mPa·s (25°C)(77°F) BROOKFIELD HADV-I
3. Substrate : PET film(untreated)
4. Recommended thickness of ink film : 14 microns(mesh : stainless 150 meshes)
5. Coverage (14 microns) : Approx. 160cm²/g
6. Thinner : TETRON THINNER
7. Washing up : VINYL CLEANING THINNER
8. Drying : 120°C(248°F) – Approx.15 minutes

1. Surface resistivity : 10.0 ohm/cm² (Tested with 4 probes)
2. Volume resistivity : 1.0 x 10^-2 ohm・cm (Tested with 4 probes)
3. Pencil hardness : H
