Designed for professional and maker use, it adheres to a wide range of surfaces including plastics, metals, ceramics, and 3D printing materials. Ideal for quick repairs, prototyping, and enhancing circuit connections, this pen ensures durable, corrosion-resistant conductivity in a convenient, easy-to-control pen format. ## Description The 842AR-P Silver conductive pen is an extremely conductive, fast drying paint in a convenient pen format. It quickly and easily creates durable, reliable, corrosion resistant, and highly conductive traces. It adheres to a wide variety of substrates. 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. Applications & usages it is used to draw traces on circuit boards or to create simple circuits on a variety of surfaces for prototyping, hobbies, or Maker projects. It can be used to repair damaged traces on keyboards, game controllers, remote controls, mixing boards, and pcb’s. Repaired devices may be returned to service in only 10 minutes. It is also great for making small connections in or between circuits such as jumpers, through-holes, bridges, and links. It is also good for increasing the surface area of contacts by painting the area around them. It is also great for filling gaps in your EMI/RFI shielding. 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. ## Features - Creates durable, reliable, highly conductive connections - Volume resistivity: 0.0001 ohms·cm - Typical trace width: 0.9 mm - Dries to touch in minutes - Adheres to plastics, epoxy, copper, aluminum, ceramics, wood, and most electronic substrates as well as ABS, PLA, and other 3D printing plastics ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 3.7 out of 5 stars 215 Reviews | ## Images ![MG Chemicals 842AR-P Silver Conductive Pen, 8.6g - Image 1](https://m.media-amazon.com/images/I/61Xp3aHJW2L.jpg) ## Available Options This product comes in different **Size, Style** options. ## 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 ## Frequently Bought Together - MG Chemicals 842AR-P Silver Conductive Pen, 8.6g - MG Chemicals 8331D Silver Conductive Epoxy Adhesive, High Conductivity, 20 min Working time, 2-Part, 14 Gram Kit --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/34818137-mg-chemicals-842ar-p-silver-conductive-pen-8-6g](https://www.desertcart.tn/products/34818137-mg-chemicals-842ar-p-silver-conductive-pen-8-6g) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-16*
