Electrically Conductive Paint 50ml - Water-Based Carbon Coating for Guitar Shielding, PCB & Remote Control Repair - Matte Black EMI/RF Shield

I've just tested this on one part of the rubber membrane keypad from an early-1990s Yamaha synth. So far so good. I can now select presets with the lightest touch rather than having to mash the keypad like a big ape to get it to register my inputs. I can't speak to the longevity of this product yet, but I'll update this review in a couple of weeks once I've used the synth a bit more.

I wanted to shield the control cavity of an electric guitar I’m putting together. I applied the paint and waited a few days. I’ve completed the wiring and grounded the painted sides of the cavity, creating a Faraday cage. It works in shielding the guitar from noise. But the paint hasn’t dried to a sealed surface, it has dried as a carbon particle powder. If I touch the sides of the cavity, I get black powder on my fingers. And it says on the container it’s a skin irritant. See picture of a white kitchen towel that I touched the surface with. And this is three days after painting. Not really suitable for my purposes. I will try a different shielding paint. You can get types that do dry completely to a sealed surface, this isn’t like that.

Purchased to repair some rubber switch contacts (the kind you get in remote controls etc.). I painted a few layers as I was a bit dubious at first, but worked perfectly and it's a big bottle if you only need to fix a few bits here and there!

Me get be my fault with regards to application (I only did one coat which covered the cavity walls) but when dry it’s really dusty and when fitting switch your fingers end up covered in black dust. Obviously this dust is conductive so now I’m trying to diagnose and suss a reoccurring switch issue, which may be due to the dust getting into the switch

The paint quality is okay and dries quickly, but it might not be suitable for all purposes, as the paint is not durable enough for my needs because it doesn't stick for long. However, it is still good for most of the intended purposes. The bottle has enough paint to apply if it comes off. I also tested it on a TV remote, and it worked fine on the rubber one but did not properly stick on plastic.

Works really well and easy to apply

I used this product to completely revive two tv remote controls that no longer worked properly. On one of them, the power button no longer worked, on the other there were other buttons that were dead. All you need to do is carefully dismantle the remote, and then use a cotton bud to paint some of the liquid onto the black underside of the rubber buttons of the remote. It dries within a minute. Then reassemble and the remote works again. It can also be used on rubber keypads that rely on conducting keys. Truly a great, versatile product.

This is just water and 'conductive carbon'. All carbon is conductive. It is way too thin and makes very high resistance PCB 'repairs'. Needs 10+ applications to get resistance below 10 ohms and the result is just carbon powder deposits that smear easily. And worst of all, you do not want to spill this stuff, but some idiot decided to put it in a bottle 10 times as tall as its narrowest base measure - Very easily toppled (I did it). Avoid this rubbish.

Die Infrarot-Fernbedienung an meinem alten Samsung-Gerät reagierte anfangs nur schlecht, am Ende gar nicht mehr. Ich habe sie zerlegt, die Kontakte auf der Platine mit Isopropanol gereinigt und dann die entsprechenden Gummikontakte mit einem Wattestäbchen mit dieser Farbe bestrichen. Nach ca. 30 Minuten Trockenzeit wieder zusammen gebaut und siehe da: das Ding funktioniert wieder wie neu. Bin schon ganz schön begeistert das es vor allem so einfach war.

Terrible product, applied on a guitar electronic cavity using instructions, have let it dry for over 24 hours and the product stains everywhere making impossible to install electronics. UPDATE: the paint also provided grounding issues when electronics installed. Had to sand most of it off to resolve. NOT RECOMMENDED

Werkt perfect om kleine reparaties aan printplaten te verrichten. Bijvoorbeeld door waterschade of lekkende batterijen. De sporen kunnen eenvoudig opgeschuurd worden en gerepareerd met deze geleidende lak. Zorg voor een heel klein kwastje!

Worked perfectly to repair a keyboard with keys that weren’t working.

resuscitato il vecchio telecomando TV: ho pulito il circuito stampato con alcol isopropiloco, idem con la tastierina gommosa. asciugato bene. applicato liquiwire con un cotton fioc, anche più di una passata, fino ad avere tutti i pad ben coperti. dopo 20 ore sembra asciutto, ma faccio anche una passata in forno di alcuni minuti (bassa temp, acceso 1 min, ventilato). senza mai toccare i pad rimonto il telecomando e... funziona !! poi vedremo la durata ma per ora ok.
