  • Makes smooth jumpers
  • Non-Ozone depleting
  • Silver-based ink

Safety Warnings

  • Class B-2 - Flammable liquid.
  • Highly flammable liquid and vapor.
  • Keep away from heat, hot surfaces, sparks, open flames and other ignition sources as container may explode if heated.
  • No smoking.
  • Use explosion proof electrical, ventilating, lighting, and all material-handling equipment.
  • Use only non-sparking tools and take precautionary measures against static discharge.
  • Keep container tightly closed.
  • Harmful if inhaled - Use only outdoors or in a well-ventilated area. Avoid breathing vapor.

Chemical Composition (CAS No.)

  • Silver (7440-22-4)
  • Proprietary Polymer(Blend)

Hazardous Ingredient

  • n-Butyl acetate (123-86-4)


  1. For smooth application, shake pen vigorously for 30 seconds before applying.
  2. Start the conductive material flowing by repeatedly depressing the pen tip on a hard, protected surface until material begins to flow.
  3. Gently hold down tip, then lift pen slightly until conductive material is released over the trace.
  4. Once desired trace is covered, let dry for 3-5 minutes. NOTE: The material needs to set completely for approximately 30 minutes in order to achieve maximum conductivity. If time is limited, it can cure in an oven, at 250-300°F (121-149°C), and reach maximum conductivity in 5 minutes.

First Aid Instructions

  1. Eye Contact
    1. Check for and remove any contact lenses.
