About MG Chemicals 842AR-P Silver Conductive Pen
Overall Feedback:
70% positive
65% appreciated its excellent corrosion protection
I found this product through online search and YouTube and used it to fix corrosion on the keyboard membrane of my Amiga A500. The product helped me to reconnect the line and fix the issue.
I was unaware of such a product existing, but I am glad I found it. I had a problem with my old Commodore Amiga A500 keyboard and after some online searching and YouTubing, I found that the problem was due to corrosion on the keyboard membrane and I was able to fix it using this product.
66% liked its fast curing time
The product takes about 5 seconds to apply and a few minutes to dry. After that, my key fob works like new.
The repair is barely noticeable, indicating that the curing time of the carbon ink is sufficient and effective.
I advise waiting for 30 minutes for it to dry completely before testing for continuity.
63% appreciated its compatibility with various substrates
It is great for fixing conductive traces on devices that use plastic membrane-like buttons, like keyboards.
I had a hard time finding something conductive enough, but this product did the trick.
62% liked its outstanding chemical resistance, though 38% experienced degradation
I am concerned about the chemical resistance of the industrial-coatings used in the pen as it emits toxic fumes. If I end up with lung cancer, I will give it two stars.
I am concerned about the coating's strong, unpleasant odor of toxic and cancerous fumes. It is impossible to avoid inhaling the fumes while painting as I need to be close to the tool.
62% praised for its high-gloss finish
Even if I have to reapply the paint every few months, it's still worth it.
64% found it to have excellent heat resistance
I have used this pen to repair the plastic membrane sheets of my IBM and Unicomp Model M mechanical keyboards. I accidentally scraped them off while cleaning away a nasty stain and fixed it using this pen.
