## Overview

MG Chemicals 842AR-15ML is a fast-drying, silver-flake conductive paint designed for superior EMI/RFI shielding on plastic and metal surfaces. With ultra-low volume resistivity (0.0001 Ωcm) and strong adhesion to multiple substrates, it offers durable, corrosion-resistant protection ideal for mission-critical electronics in medical, military, aerospace, and consumer devices.

## Description

The 842AR Silver conductive coating is a highly conductive coating that protects electronic devices in plastic Enclosures from high frequency electromagnetic and radio frequency interference (“EMI/RFI”). it is a durable acrylic lacquer pigmented with a high purity Silver flake. It is easy to use solvent based system, with no heat cure necessary. It has excellent conductivity, strong adhesion to plastics, great oxidation resistance, and has a wide variety of applications. The 842AR is designed to provide a highly conductive surface to the interior of plastic electronic Enclosures to suppress high frequency EMI/RFI emissions, allowing compliance to FCC rules, and protecting the device from external EMI/RFI, preventing possible malfunction. Silver is offers the strongest EMI/RFI suppression, especially at higher frequencies, and it can be applied very thin, so it is the optimal pigment for short range EMI applications, such as board level or component to component applications. It is also optimal in military, medical, or other mission critical applications, where the highest levels of attenuation are essential. 842AR adheres well to wood, copper, aluminium, and many other surfaces beyond just plastics. It is a simple an effective solution to many applications where it is necessary to impart maximum conductivity to a surface. Applications: repairing damage to existing shielding, conductive undercoat for electroplating, providing electric continuity for circuits, medical equipment, military equipment, scientific equipment, Test equipment, communication devices, cell phones, laptops, pda’s, consumer electronics, automotive applications, aerospace applications, drones and other RC vehicles.

Review: Doesn't work and the fumes are lethal - I used Tamiya masking tape on a rear screen, out of the car, to form 1.5mm wide channels and filled these with this product up to the copper tracks that still showed voltage and ensured a good 1cm overlap. The fumes were overwhelming, a respirator was no use and in a large open workshop, fully ventilated with a fan blowing across the work area, the fumes were unbearable, triggering an asthma attack and streaming eyes, the fumes hit anyone who walked through the building like a hammer and could be smelt two units away. I left the first two tracks to cure overnight and next day they showed no continuity across and carried no voltage whatsoever; basically lethal and utterly useless.

## Questions & Answers

**Q: How long does this last once opened? I want to have this on hand for small electronic repairs over the course of time**
A: It lasts a long time, but it does dry out quickly.  You need to get a can of thinner (435-1L) and add thinner as needed.  Even if the Super Shield container is completely dried out and solidified, if you add thinner, it will be liquified again.

**Q: Would this work for coating pp+eva plastic hard drive case to protect stored drives from emp?**
A: I doubt that this paint would protect stored drives from emp. This item is simply electro-conductive paint.  We use it in our Physics Labs at the community college level.  It is a good product but it is not as good as the predecessor product "Silver Print," which had better conductivity.  Super Shield is most commonly used to paint circuits onto a circuit board. So I don't see how painting plastic hard drive cases with it would protect the hard drive inside from emp.  My advice would be:  Avoid explosions of nuclear weapons, if at all possible.

**Q: What should be used to thin this paint?**
A: MG makes a thinner for the Super Shield product.  The product number is 435-1L, I think.  Just go to the MG Website; they have complete information available.  You really need to get the thinner, because the product dries out very quickly while you are using it.  You need to keep adding thinner.

**Q: How will this perform under different temperature ranges? Mainly I am looking for a range of between 0 and 180 degrees Celsius.**
A: Check the MG website; they have better information on the product than I can tell you, and it's very easy to find.

### ⭐⭐⭐⭐⭐ Review
*by B***C on 14 January 2023*

I had to use this on a speaker voice coil. It's a dual voice coil subwoofer and the leads were soldered under the dustcap, then covered in CA glue. So, uncovering that would have been quite a chore. I removed some of the paper over the coil leads running up the former and applied several coats of this. I don't measure any resistance. I then ran 1000 watts through the woofer just to see if this would burn like a fuse. It did not nor did it get warm. That makes sense given that it doesn't have any measurable resistance. I covered it with CA glue and that is a repaired woofer.
