## Overview

The MG Chemicals 842AR-P Silver Conductive Pen delivers ultra-low resistivity (0.0001 Ω·cm) silver ink in a convenient pen format, enabling rapid, precise repairs and prototyping on a wide range of substrates. It dries quickly at room temperature, forming durable, corrosion-resistant conductive traces ideal for electronics enthusiasts and professionals alike.

## 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 centre 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.

Review: Excellent to fix broken remote controls - I had a few remote controls where most of the keys stopped working due to the carbon wearing off the membrane pads and not making sufficient contact with the PCB. Putting a blob of this carbon compound on the carbon pads of the membrane fixed the problem entirely. A few tips; - wear gloves, this stuff is messy and carcinogenic - shake the pen for 30s - use a sheet of paper to clean the nib - make sure the surface is clean, IPA+cotton bud - leave for 24 hours for conductivity and strength
Review: Works well, needs time to dry - Works good, used to fix a trace on the pcb in my car’s cruise control stick. Only gripe is that you can’t really control how much comes out very well. Also note: whatever you’re doing / fixing won’t work until the ink has completely dried. Found out after 30 mins of pure worrying that I’ve wrecked the pcb I was working on.

## Questions & Answers

**Q: Can this be used to repair car rear screen heaters?**
A: I don't recommend this product for the rear screen heaters because it will not adhere well to the surface.  Instead I would recommend our electrically conductive adhesives like the 8331 which many people have used for this type of repair

**Q: Can you solder on it? i want to rebuild the lost copper on pcb**
A: Hello, 
The soldering process is usually performed at high temperatures (around 200C) and the 842AR-P can only withstand temperatures up to 120C. Based on that, we do not recommend soldering on top of the silver coating. 
Thank you,

### ⭐ Not conductive, but can make a lovely resistor with it
*by D***H on 21 April 2024*

expected this to be conductive like the description said. But it's not. It has resistance. So not suitable for what I needed, repairing broken circuit traces. This is similar to the carbon in a solution products you can buy at car shops. Not recommended. But it does dry quick.
