Creative Materials 118-41

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.

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.

Shelf Life
  • 3 months at 25°C; or 6 months at 5°C; or 12 months at –10 ºC.
