Creative Materials 119-28

119-28 is an extremely flexible, pad printable, electrically conductive, carbon filled ink, coating and adhesive suitable for application by pad 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 119-28 include, but are not limited to, polymer thick film circuitry and membrane switches. 119-28 is a pad-printable version of 108-46.

Suggested Handling & Curing

119-28 is ready to use as supplied. Further thinning may be accomplished by adding small amounts of CMI Thinners #113-39, or 114-20. Prior to using, be certain to resuspend filler. Best properties, for most applications, result when cured for 10 minutes at 105°C. Good properties are obtained on a variety of substrates by dry and curing at temperatures ranging from 50°C to l80°C. End user is advised to experimentally determine temperature and time best suited for individual applications.
