## Overview

The MG Chemicals 838AR-P Total Ground Carbon Conductive Pen delivers fast-drying, corrosion-resistant conductive traces with a low volume resistivity of 0.46 ohms·cm. Its valve tip and soft tube design enable precise control over 1.0 mm wide traces on a wide range of substrates including plastics, metals, ceramics, and 3D printing materials. Ideal for professional prototyping, repairs, and Maker projects, it offers a durable, economical alternative to metal-based conductive paints.

## Description

The 838AR-P carbon conductive pen is a conductive, fast drying paint in a convenient pen format. It quickly and easily creates conductive traces that are durable, reliable, and corrosion resistant. It adheres to a wide variety of substrates. The paint is a tough acrylic polymer pigmented with high purity Carbon black. The Carbon black imparts superior corrosion resistance as well as high conductivity. This product works best on smooth, flat, and hard surfaces. It has a Valve tip that opens when the pen is pressed against the surface to be drawn on and it has a soft tube, so the flow may be controlled by squeezing the center of the pen. It is used to draw resistors and connect grounds in prototyping, hobbies, or Maker projects. It can be used to create traces where a higher resistance connection is desired such as when drawing in jumpers or other simple electrical connections. It is good for restoring conductivity to contact surfaces and extending contact areas. Use it as an economical alternative to nickel or silver paints where extreme conductivity is not required. Attention! shake rigorously before use. For best results hold pen at angle, depress pen tip against surface, and draw pen across surface while gently squeezing middle.

Review: Easy to apply and conductive. It's not metal conductive since it presents tents to hundredths of ohms resistance but gets a small repair done
Review: No es para cualquiera, pero debes de saber cómo aplicar el producto , para realizar trabajos es muy bueno , perfecta conductividad y muy bueno porque lo ocupo para trabajar las membranas de los hornos de microondas y ninguno tuvo falla ... Todo muy bien ,comprare otro 👍

## Questions & Answers

**Q: Will this work to coat the non-working rubber buttons on a remote control**
A: Yes, this worked great. First, clean the circuit board where the contacts are using Isopropyl alcohol.  I also used Iso to clean off the rubber dot, which is usually a conductive carbon substance.  Then apply the *carbon* version of this product to the black dot.  Cover the whole surface and let it dry completely before re-assembling.

**Q: Can this be used to repair a broken strip in a car rear defogger?**
A: I just tested a 1/2" long x1/8" wide strip on a piece of pyrex glass and got 0 resistance for that length. It seems to conduct well for a short distance and stuck to the glass very well. I hope this helps.

**Q: Does it work for making a PCB?**
A: In my opinion, it's far from the ideal for making your own PCB. I can see it being used for prototyping of low voltage/low current circuits.This particular compound is based on nickel, which is not a as conductive as copper.This pen would work fine for the small repairs like cuts or tears in the existing PCB traces. BTW, there's a more conductive version of this pen which is based on silver.Aside from conductivity issue, there's an issue of securing parts to PCB. I,also, doubt you can solder to the trace drawn with this pen.

**Q: Is this pen good for making a jumper on a circuit board?**
A: Yes, it's great for that but even the carbon conductive (lowest quality) pen would work for that

*by S***K on 31 August 2024*

Kann das produkt nicht guten herzens weiterempfehlen. Ist zwar conductive, aber das ist ein gaphit bleistift auch. Auf 1cm strichlänge hat man schon 120k ohm widerstand, bissl weiter gehts in den mega ohm bereich. Der widerstand is so gross, das man nichtmal bei 2mm linie einen ton aus dem multimeter bekommt wenn man auf durchgang testet..kann nur widerstand messen. Mag vielleicht bei nem kratzer auf ner pcb leiterbahn helfen um zu überbrücken..mehr aber auch nicht. Bei dem preis gibt es bessere möglichkeiten ein pcb zu fixen.
