Creative Materials 119-21
- Chemical Family
- Silver & Silver Compounds
119-21 is a pad-printable, solvent-resistant, electrically conductive ink and coating, suitable for pad-printing very narrow circuit lines. This product features excellent adhesion to Kapton, heat stabilized polyester, glass and a variety of other substrates. Unlike conventional conductive materials, this product is very resistant to acetone and methyl ethyl ketone. It is also very resistant to scratching and creasing. Some applications for 119-21 include, but are not limited to, emi/rfi shielding of polyimide flexible circuits, polymer thick film circuitry, membrane switches, electrical attachments for surface mounted devices, and anode coatings for tantalum capacitors. 119-21 is a pad-printable version of 118-41.\nFeatures

- Suggested Handling and Curing
119-21 is ready to use as supplied. Further thinning may be accomplished by adding small amounts of CMI Thinner #113-39 (fast evaporating) and/or Thinner # 114- 20(slow evaporating). Prior to using, be certain to resuspend silver. Best properties, for most applications, result when cured for 45 minutes at 160°C or 30 minutes at 175°C. The use of B119-44 accelerator will allow for lower temperature curing providing good properties when cured from 50°C to 150°C. End user is advised to experimentally determine temperature and time best suited for individual applications.
