 120-24
 ELECTRICALLY CONDUCTIVE CARBON FILLED EPOXY INK
DESCRIPTION: 120-24 is a carbon filled, screen-printable, electrically conductive, epoxy-based ink and
coating suitable for application by screen- printing, dipping and syringe dispensing. This product features
excellent adhesion to Kapton, Mylar, glass and a variety of other surfaces. Unlike conventional conductive
materials, this product is very resistant to flexing and creasing. Some applications for 120-24 include, but
are not limited to, printed potentiometers, printed resistors, emi/rfi shielding of polyimide flexible circuits,
polymer thick film circuitry, membrane switches and anode coatings for tantalum capacitors. 118-41 is a
0.01 Ω/sq/mil silver version of this product.
TYPICAL PROPERTIES:
Viscosity (cps) 27,500
Filler Carbon
Sheet Resistivity, max. (Ω/sq/mil) 50*
Volume Resistivity, max. (Ω-cm) 0.13
Hydrolytic Stability Excellent
Useful Temperature Range (°C) -55° to +200°
Thermal Stability (°C) Good to +280°
* Cured 10 minutes at 175º C in a convection oven
SUGGESTED HANDLING & CURING: 120-24 is ready to use as supplied. Further thinning may be
accomplished by adding small amounts of CMI thinner 102-03. Prior to using, be certain to re-suspend
filler. Best properties, for most applications, result when cured for 10 minutes at 175°C. Good properties
are obtained on a variety of substrates by dry and curing at temperatures ranging from 50°C to 200°C.
End user is advised to experimentally determine temperature and time best suited for individual
applications.
STORAGE: Shelf life: 3 months at 25°C or 12 months at -10°C.
SAFETY & HANDLING: Use with adequate ventilation. Keep away from sparks and open flames. Avoid
prolonged contact with skin and breathing of vapors. Wash with soap and water to remove from skin.
