MG Chemicals 841AR-P - Nickel Conductive Pen

Nickel Conductive Pen 841AR-P pen dispenses an acrylic lacquer pigmented with conductive nickel flakes. The cured traces are durable and corrosion resistant. They adhere well to plastics and most electronic substrates. The traces are flexible, but the product works best on a smooth, flat, hard surface. The valve tip opens when pressed against the surface, and the flow is controlled by squeezing the barrel. This pen repairs damaged traces on keyboards, game controllers, remote controls, mixing boards, and PCBs. It also creates conductive traces for prototyping, hobbies, or maker projects. It is great for making small connections in or between circuits, such as jumpers, through-holes, bridges, and links. It can also be used to increase the surface area of contacts by painting the area around them. For applications requiring lower resistance, use the 842AR-P Silver Conductive Pen. For a more economical alternative, use the 838AR-P Carbon Conductive Pen.

Cure Instructions
Allow to dry at room temperature for 24 hours, or after letting sit for 1 minute, cure the coating in an oven for 30 minutes @ 65 ˚C.
Recommended Preparation
Clean the substrate with Isopropyl Alcohol, MG #824, so the surface is free of oils, dust, and other residues.
Application Instructions
  1. Shake pen vigorously until the ball moves freely inside.
  2. Hold pen at angle and depress tip against surface.
  3. Draw pen across surface while gently squeezing barrel.
  4. Let dry 1 min before handling or heat cure.
  5. Clean tip, replace cap and store tip up after use.
