 118-41
SOLVENT-RESISTANT ELECTRICALLY CONDUCTIVE INK
DESCRIPTION: 118-41 is a solvent-resistant, screen-printable, electrically conductive ink and coating. This product
features excellent adhesion to Kapton, Mylar, glass, polycarbonate and a variety of other substrates. Unlike
conventional conductive materials, this product is very resistant to acetone and methyl ethyl ketone (MEK). It is
also very resistant to scratching and creasing. Some applications for 118-41 include, but are not limited to, emi/rfi
shielding of polyimide flexible circuits, polymer thick film circuitry, membrane switches, electrical attachments for
surface mounted devices, and anode coatings for tantalum capacitors. 120-24 is a 50 Ω/sq/mil carbon version of this
product.
TYPICAL CURED PROPERTIES:
Viscosity (cps) 18,000
Filler Silver
Percent Silver (cured) > 89
Crease Resistance Excellent
Volume Resistance (ohm-cm) 0.000025
Sheet Resistivity (ohm/sq./mil) 0.010
Solderable No
Hydrolytic Stability Excellent
Useful Temperature Range (°C) -55 to 200
Thermal Stability (°C) Good to 325
SUGGESTED HANDLING & CURING: 118-41 is ready to use as supplied. Further thinning may be accomplished
by adding small amounts of CMI Thinner #203 and/or Thinner # 113-12. Prior to using, be certain to re-suspend
silver. Best properties, for most applications, result when cured for 45 minutes at 165ºC or 30 minutes at 175ºC.
End user is advised to experimentally determine temperature and time best suited for individual applications.
STORAGE: Shelf life: 3 months at 25°C; or 6 months at 5°C; or 12 months at –10 ºC.
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.
