MG Chemicals’ carbon conductive pen is a conductive, fast drying paint in a convenient pen format that adheres to a wide variety of substrates. It quickly and easily creates conductive traces that are durable, reliable, and corrosion resistant. This pen contains a tough acrylic polymer paint that is pigmented with high purity carbon black which imparts superior corrosion resistance as well as high conductivity. This carbon conductive pen can be used to draw resistors and connect grounds in prototyping, hobbies, or maker projects. It is good for restoring conductivity to contact surfaces, extending contact areas and creating traces where a higher resistance connection is desired.
