## Overview

The MG Chemicals 842AR-PS Silver Conductive Pen dispenses a silver-flake acrylic lacquer that dries in 1 minute to form durable, corrosion-resistant conductive traces with ultra-low resistance (0.3–0.8 Ω/cm). Ideal for repairing and prototyping on plastics and electronic substrates, it features a precision valve tip for controlled application and flexible, reliable conductivity on smooth surfaces.

## Description

842AR-P pen dispenses an acrylic lacquer pigmented with highly conductive silver flakes. The cured traces are durable and corrosion resistant. They adhere well to plastics and most electronic substrates. The traces are flexible, but the product works best on a smooth, flat, hard surface. The valve tip opens when pressed against the surface, and the flow is controlled by squeezing the barrel. This pen repairs damaged traces on keyboards, game controllers, remote controls, mixing boards, and PCBs. It also creates conductive traces for prototyping, hobbies, or maker projects. It is great for making small connections in or between circuits, such as jumpers, through-holes, bridges, and links. For applications where high conductivity is not required, the 838AR-P Carbon Conductive Pen and the 841AR-P Nickel Conductive Pen provide economical alternatives.

Review: Works great for repairing keyboard membranes - I've been using these to repair the plastic membrane sheets of my IBM and Unicomp Model M mechanical keyboards for several years and have gone through at least three so far. The silver pens are expensive, but I read somewhere that it's best to keep using the same metals throughout, so I buy those. They're not the most intuitive to use, so you should make sure to try it out on a piece of scrap paper or something you're not afraid to ruin to get the hang of it. Always make sure to give it a good shake first (like a paint marker) and squeeze the body while laying the ink down. And if you mess up, even after it dries, it's easy to scrape away with something like a screwdriver or an exacto knife, at least on smooth plastic. My picture is of some traces I repaired on a Model M membrane. I accidentally scraped them off while cleaning away a nasty stain and fixed it using this pen.
Review: Terrible product, practically unusable. - Although the ink is conductive and fairly low resistance, it flows terribly. This comes down to two factors. The thickness of the ink, and the design of the pen. There are literally children's products that work better than this. In fact you could do better with an alcohol ink that you buy at a craft/hobby store. The ink probably won't be quite as low resistance, but at least you can write with it. The lines are way too thick, the ink is goopy, and flows terribly. And using this for any kind of circuit testing or prototyping on paper is laughable.
