125-04 Technical Datasheet

ELECTRICALLY CONDUCTIVE INK

DESCRIPTION 125-04 is a silver/copper alloy, electrically conductive 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 125-04 include, but are not limited to, RFID antennae, emi/rfi shielding of polyimide flexible circuits, polymer thick film circuitry and membrane switches. This is a silver plated copper version of 101-59.

SUGGESTED HANDLING & STORAGE 125-04 is ready to use as supplied. Further thinning may be accomplished by adding small amounts of CMI Thinner # 102-03 and/or butyl cellosolve acetate. Prior to using, be certain to re-suspend silver. Best properties, for most applications, result when cured for several minutes at 150°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.

 

HEALTH AND SAFETY Use with adequate ventilation. Keep away from sparks and open flames. Avoid prolonged contact with skin and breathing of vapors. Wash with soap and water to remove from skin.

All technical information is based on data obtained by CMI personnel and is believed to be reliable. No warranty is either expressed or implied with respect to results or possible infringements on patents.
