Creative Materials 120-24

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.

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.
