MG Chemicals 842AR-P Silver Conductive Pen, 8.6g

I was working on a Turbo Express system with non-functional buttons. The capacitor on the controller board had leaked and dissolved the carbon traces for the buttons, so I purchased this carbon ink to see if I could use it for a more 'authentic' repair rather than jumping the traces or replacing the board in its entirety.After practicing drawing a bit on some regular paper, I cleaned the traces thoroughly, took a bit extra off the damaged sections and contact points and carefully applied the carbon ink. Most went on pretty easily (follow the instructions, they are helpful) however there were a couple spots where I flowed a bit too much and had to clean / reapply. Overall, it took maybe 15~20 minutes to read the instructions, practice a bit and perform the repair / get it how I wanted it (this being my first time using conductive ink, so next time it shouldn't take as long). My repair is barely noticeable!Most importantly... I let it dry for 10 minutes and tested everything out, and all buttons worked perfectly!This stuff is a God send. Follow the instructions and it really isn't difficult to properly apply... Make sure you thoroughly clean any surfaces you plan to write on, and remove a bit extra from damaged sections and contact points of existing traces, squeeze the pen firmly but not excessively while applying pressure to the ball point and use deliberate motion...Great product!

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.

I had to give this conductive paint a try before forking over $80 for a used remote control for my receiver/amplifier. Upon opening the package, all seemed well. First, I read all the dangers and precautions of using this product. Too bad it was in very small print. Second, there were no instructions on how to use the product. Nothing to tell me if I need to shake the tube first (which I didn't do), how to apply it to the work surface or how long to let it dry. So, after reading how dangerous this stuff is, I put on a pair of safety glasses and a face mask. At first, nothing came out of the pen, so I pressed the pen onto the surface and noticed the paint coming out. I applied it to the work area, waited about 5 minutes for the paint to dry, assembled the remote control, put the batteries in place and viola - my remote control is new again. Even if I have to reapply this paint every few months, it's worth it. So, for $10.45, it was worth a try.

How can I not return an item that simply doesn't work. That is completely beyond me. I spent almost $50 for a defective item that now cannot be returned or I don't get a refund for??? Wow! Just wow! I think I need to reconsider buying here.Ok. To the pen: I followed the instructions. The ink doesn't flow out. End of story.Zero stars if that was possible for the pen.And minus 5 stars for Amazon customer care.

si es tremendo producto, pero pregunte antes de comprar , no es para todo los usos, hay que saber que es loque vas a querer lograr , para cpmo ejemplo , pistas de conexion etc etc, lo recomiendo

Pen worked great for its intended purpose, but when I pulled top off it exploded, the tip had some think glue-like substance and when the top cap came off it pulled the tip out of pen, which leaves a 1.4-inch hole. SO it sprayed the insides all over me. HOW, well the top does take some effort to pull off, which makes a slight jerk when it does come off. I have ruined a shirt and jeans and lost almost all the contents, let alone left spots on my carpet. But what was left worked well. Not sure what the glue-like substance was, very much like rubber cement. The product works, but watch out taking top off.

I'm very glad this product exists. Saved me hundreds of dollars!The material flows pretty well once you get the hang of it. It's similar to a paint pen, but with nickel in solvent. Let it dry! It wont conduct until the metal settles and the solvent dries. It was fun to use a multimeter and watch the resistance drop as the fluid cured.I used this to repair a laminated keypad ribbon cable in a microwave that somehow got a melty trace. I also used it to repair the damage I did trying to fix the problem before i knew this product existed. It will now and forever be a part of my electronics kit. Perfect for membrane trace repair!Adhesion is good on plastic. The output width is about 2mm. It's a fluid but not super runny, especially after the solvent flashes off. Build up a couple of coats for best conduction.It takes a minute to get used to dispensing the material. The pen uses a plunger valve tip that has to be pushed against the surface before flow will start. You control the flow with how hard the tube is squeezed. Wiping the tip after every lift-up makes things go smoother.

Used this to repair the contacts on a garage door keypad. Works like new. Recommend

Kann das produkt nicht guten herzens weiterempfehlen. Ist zwar conductive, aber das ist ein gaphit bleistift auch. Auf 1cm strichlänge hat man schon 120k ohm widerstand, bissl weiter gehts in den mega ohm bereich. Der widerstand is so gross, das man nichtmal bei 2mm linie einen ton aus dem multimeter bekommt wenn man auf durchgang testet..kann nur widerstand messen. Mag vielleicht bei nem kratzer auf ner pcb leiterbahn helfen um zu überbrücken..mehr aber auch nicht. Bei dem preis gibt es bessere möglichkeiten ein pcb zu fixen.

This just saved my stream deck from death.Laid it on fairly heavily over a broken trace for the keyboard membrane. Testing conductivity a few hours later it did not look promising. Testing provided no improvement. So I put it in to the pile of disappointment and sorrow. A few days later I thought lets try it again but low and behold it was working! I guess it takes a few days to properly cure.Phew. £140 saved!

Very useful. It is just like a correction pen.But when I used it, soon the tip got blocked and no more ink was flowing. So I had to cut open the body and use a small stick to scoop the ink and paint.However, ink is good, dries fast, sticks well on plastic surface.I ordered it to repair keypad of an old spectrometer. We saved around 1-2,00,000 rupees.

This stuff really works. Fixed a calculator with broken trace under a button. Will try to use it on a rear window heater in the car. Higher currents, but maybe it will work too.
