Creative Materials 121-30

121-30 is a carbon / silver filled, electrically conductive ink and coating for application by screen-printing, dipping and syringe dispensing. The product features excellent adhesion to Kapton, Mylar, glass and a variety of other substrates, including transparent conductive oxide coatings. Unlike conventional conductive materials, this product is very resistant to abrasion, scratching, flexing and creasing. Some applications for 121-30 include, but are not limited to, EMI/RFI shielding of polyimide flexible circuits, polymer thick film circuitry, solar cell and touch screen bus bar applications and back electrodes on electroluminescent devices.

Suggested Handling & Curing

121-30 is ready to use as supplied. Further thinning may be accomplished by adding small amounts of CMI thinner #120-08 Prior to use, be certain to mix well to resuspend fillers. Best properties, for most applications, result when cured for 30 minutes at 90°C. Excellent properties are also obtained on a variety of substrates by curing at temperatures ranging from 50°C to 175°C. End user is advised to experimentally determine temperature and time best suited for individual applications.
