MG Chemicals Carbon Print (Conductive Paint)

Easy to use. I apply to traces with a toothpick. This paint has just enough conductivity to repair damaged traces on my keyboard. In hindsight I should have bought the silver-based paint, or something more conductive. But it does work for keyboard repair. It should also work to repair carbon pads of certain kinds of keypads. Would work great for making resistors on paper. The specs for resistance are in the product specifications. Be sure to let the paint completely dry before trying to use or measure the resistance. Anyway my keyboard is functioning again, and I'm happy. Seems a shame to throw out a keyboard over a couple of deteriorated traces. This fixed it.

Painting a circuit worked just fine. The liquid evaporates quite quickly and the odor is very strong. You really need to be in a well ventilated space. I was a bit surprised to find that all I needed to do remove the paint was to wash it off with water (this was more than 24 hours after it had dried).

I bought to copper plate 3D printed parts, and it simply does not work, I have tried multiple times in vastly different approaches all with the same result, only small spots of copper will be plated and the adhesion is only slightly better than using nothing at all. Enormous disappointment. I was able to plate aluminum with it, it worked so well I thought I had finally found the ideal conditions to make it work, tried PLA again, and the results were even worse than before. Don't bother with it if your going to electroplate 3D prints, it's a waste of money and worse, a gigantic waste of time and effort. Even using graphite lubricant for locks mixed with nail polish remover worked substantially better. Going to try actual graphite powder this was sadly a total bust.

This conductive paint worked very well for recoating the conductive undersides of the buttons on one of our remotes. It is easy to apply and easy to clean up (use acetone). It dries VERY fast, and I did not think the VOC's from the paint were much stronger than any other paint. On important thing to keep in mind is what are your requirements for your project. The paint is conductive, but it is not as conductive as metal. When performing a continuity test on the paint, there is resistance that is about of about 25 to 30%. For the application I was using the product, that level of resistance was not an issue. However, this paint does not replace the use metals when the need is for minimal resistance. Finally, be sure to shake the bottle well, and ensure that you have decent coverage. If what you painted does not have a flat finish to it, you probably did not use enough of the paint. Bottom line... If this paint is used within the parameters it was intended, it will perform very well.

I made this small idol a couple of months ago by hand-shaping a 50-50 mix of beeswax (amazon) and Vaseline (amazon). I then painted it over with this carbon paint. I used a copper ingot (amazon) for the anode and plated at ~50mA and ~1V through a solution of cus04 root killer (amazon) and 2tsps of h2s04 battery acid (O'Reillys). I believe the plating is about 1-2mm thick. It was plated for around 10 days, almost 24/7. I was able to drill tiny holes on the bottom to drain out the wax, but decided to leave it in there to let the sun do the job in summer. I hope this helps someone looking for something that specific. & PS. I suspect many people have a bad electroplating experience because they didn’t use distilled water. I found this to be super important to prevent impurities depositing on the cathode which distorted the target. 4-stars instead of 5 cuz I think it dries too quickly. I could compensate somewhat by thinning with Acetone (Nail polish remover), but would have preferred a differently structured mouth with built in brush, even if 25c more. PS2. I asked in the QA for this product if nail polish remover works to thin it down and no one answered (see above). So I gave it a shot and found it worked (see above).
