Creative Materials 127-20A/B

127-20 is a two component, pad printable, conductive ink/coating for application by pad printing, dipping and syringe dispensing. The product features excellent adhesion to pretreated polyethylene, and polypropylene, as well as to some varieties of pretreated polytetrafluoroethylene. This material will also adhere to Polyurethane, polyamide, melamine, phenolic resins, metal, and glass substrates. Unlike conventional conductive materials, this product is very resistant to abrasion, scratching, flexing and creasing. Some applications for 127-20 include, but are not limited to, emi/rfi shielding, flexible circuits, and membrane switches.

Suggested Handling & Curing

Prior to use, be certain to mix well to re-suspend filler. Mix parts A, and B as prescribed above. Further thinning may be accomplished by adding small amounts of CMI thinner 113-39 or for slower drying 114-20, and/or 114-28 for drying rates between the two. End user is advised to experimentally determine temperature and time best suited for individual applications.
