Creative Materials 121-35(UT)

121-35UT is an electrically conductive ink and adhesive suitable for application by screen printing, dipping and syringe dispensing and designed with high temperature applications in mind. Unlike conventional conductive materials, his product features a unique high continuous operation temperature and very high glass transition temperature making it especially well-suited for extreme conditions found in furnace, heater, and aerospace applications. This product features excellent adhesion to a wide range of substrates such as Kapton, Mylar, ITO sputtered surfaces, glass and a variety of other surfaces without the addition of treatment via acid or plasma etch. This product is very resistant to flexing and creasing and is suitable for very fine lines and spaces. Some applications for 121-35UT include, but are not limited to, EMI/RFI shielding of polyimide flexible circuits, polymer thick film circuitry, and membrane switches. 121-35UT is a conductive carbon version of 110-19UT.

Suggested Handling & Curing

121-35UT 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 resuspend filler. Best properties for most applications result when pre-curing for 30 minutes at 150°C followed by curing for 60 minutes at 250°C. Good properties are obtained on a variety of substrates by dry and curing at temperatures ranging from 150°C to 250°C. End user is advised to experimentally determine temperature and time best suited for individual applications.
