Carbon, nickel and silver microtip pens

EM-Tec conductive micro-tip pens enables writing conductive tracks, traces and lines on non-conductive materials. Ideal for making conductive paths for SEM specimens, making visible markings on SEM specimens, repairing defective tracks on circuits or for prototyping. The ink in the microtip pen is filled with either silver, nickel or carbon polymers which exhibits excellent adhesion properties on most materials. The conductive traces dry fast and conductivity is achieved when the ink is cured. The conductive traces can be used on flexible substrates. The cured traces can be easily removed with acetone

  • Creates durable, reliable conductive traces
  • Micro-tip of 0.8mm with typical trace width of 1.5-2.0 mm
  • Visible and conductive marking of SEM specimens
  • Dry to touch in one minute at room temperature
  • Strong corrosion resistance
  • Service (use) temperature: 40 to 120 °C
  • Does not contain toluene, xylene or MEK


1 – EM-Tec AG20 silver conductive micro-tip pen with silver-filled ink for best results. Makes excellent conductive traces and highly visible markings on SEM specimens
2 – EM-Tec NI20 nickel conductive micro-tip pen with nickel-filled ink for less demanding applications to make conductive traces and visible markings on SEM specimens
3 – EM-Tec C20 carbon conductive micro-tip pen with carbon-filled ink is a cost-effective option for making conductive traces and conductive markings on SEM specimens

Instructions for use:
Although the silver ink has been formulated to resist hard packing, it is recommend to shake well before use until the ball inside moves freely. Hold pen at an angle and depress tip against surface; draw pen across surface while gently squeezing the barrel of the pen. Clean tip, replace can and store with the tip upwards after use. Leave to dry for one minute before handling or heat curing
