JELCON CH-10
(low-resistance carbon paste with low price)

We stopped production of this INK. (Dec., 2010)

We stopped production of this INK. The following information is just for your reference.

INTRODUCTIONS

DDRJELCON CH-10 is carbon paste of one-component polymer type designed for the flexible printed circuits of membrane switches. The resistance is low(lower than CH-1 approx.by 20%). CH-10 makes it possible to improve the performances of the printed matter as well as to save the cost.

JELCON CH-10 is used for the parts of the dancing game machine that is very popular now.

CHARACTERISTICS

  • Low resistance. 10.0 ohm/cm², thickness : 14 microns
  • Low price with good cost-performance
  • Good adhesion to PET film.
  • Excellent flexibility.
  • One component type. Stable in long storage. Good printability.
  • Compatible with silver paste of other makers.

HOW TO USE

  • Specific gravity(20deg.C) : 1.15
  • Viscosity(dPa.s) : 300 (VT-04 Visco-tester, No.2 spindle, 25deg.C)
  • Substrate : PET film
  • Recommended thickness of ink film : 14 microns(mesh : stainless 150 meshes/inch)
  • Coverage (14 microns) : Approx. 160cm²/g
  • Thinner : TETRON THINNER
  • Washing up : VINYL CLEANING THINNER
  • Drying : 120deg.C - Approx.15 minutes

PROPERTIES(Thickness of the ink film : 14 microns)

  • Surface resistivity : 10.0 ohm/cm² (Tested with 4 testing needles)
  • Volume resistivity : 1.0 x 10-2 ohm/cm² (Tested with 4 testing needles)
  • Pencil hardness : H
  • Adhesion(cross-hatch) : 100/100

ENVIRONMENTAL PERFORMANCES

  • Heat shock(-20deg.C&+80deg.C, 2 hours, 10cycles) : The rise in resistance <10%
  • Heat resistance(150deg.C, 72hours) : The rise in resistance <10%
  • Humidity resistance(40deg.C, 90%RH, 240hours) : The rise in resistance <10%
  • Resistance at bending(bent at 360degrees) : The rise in resistance <20%

PRECAUTIONS

  • The informations given here are obtained from our laboratory testing and no firm guarantee is implied.
