Best Electrically Conductive Adhesives of 2025

"I found that silver epoxy made replacing the battery in my Norelco shaver incredibly straightforward. I didn’t need any soldering tools, just a heat gun to cure it. By doing this, I saved my shaver from ending up in a landfill and saved a good amount of money compared to buying a new one."

"Having previously tried various defrost repair kits with little success, I was skeptical about this product. However, I finally decided to invest in it, and I wish I had done so sooner. The epoxy hardened like concrete, maintaining electrical conductivity, and I was able to fix the defrost tab on my car effectively."

"I chose this silver epoxy for its reputation, even though it was pricier. After a practice run, I found it a bit difficult to mix due to its thick texture, but it worked wonders for my repair on a potentiometer. Despite the mixing challenge, I believe it was worth the investment."

“I had a solder break on my Jeep's rear window defroster. The dealer quoted me $235 for the repair! Not wanting to pay that, I found this silver conductive glue. After following the instructions carefully, it worked great! I applied it to a small area and allowed it to cure, and I highly recommend this product.”

“I was hopeful this product would solve my issue, but it did not work for me. I followed the instructions and let it set for three days, but when I turned on the defroster, I saw smoking and an orange glow. Unfortunately, the connection just fell off the window afterward. It's frustrating because this is a single-use glue.”

“This product worked wonders for me! I used it to re-glue traces on a circuit board, and it performed flawlessly. After mixing it as recommended, I found it to have little resistance. Just a tip: prep the surfaces well, or it might not bond properly.”

"I found the adhesive on this copper foil tape to be incredibly strong, sticking well to almost any surface without leaving a sticky residue when removed. It worked perfectly for my EMI shielding in guitar projects and provided excellent grounding. I've had no issues with it not adhering or losing its conductivity. Great length for the price!"

"I used this copper tape to shield my guitar, and it was a great upgrade from the aluminum tape that came with it. Be patient and take your time, and you'll get a nice end result. I’m hoping this will help with my rabid squealing problem!"

"This tape has worked 100% effectively in my garden to deter snails. I applied a layer of duct tape as a base before using the copper tape, and it seems to confuse the snails. I do recommend using gloves, as the tape is sharp and can cut easily."

"I found this product to be effective for minor repairs. Initially, it worked great to fix the connection on my humidifier, but it loosened after a few days. After adding super glue, it has held up for two months without issues."

"I used this conductive paint on the underside of my remote control buttons. It was easy to apply and worked perfectly after drying. I didn't even read the instructions!"

"I was disappointed with this product. It really doesn't function as a true adhesive. It just coats the surface and doesn't stick well, which made my repair unsuccessful."

"I used this adhesive to attach a large aluminum heat sink to a small Asus 680 chipset cooler. It worked great, lowering the temperature by about 10°C into the low 50°C range. I followed advice from other reviews and placed a weight on the heat sink, allowing it to cure for about 36 hours. I’m confident it won’t come off without significant force, which is perfect since it’s all housed in a glass case."

"After using this adhesive to bond some old computer heatsinks to my shop's minifridge, I found that it stuck perfectly, even on a slick, enameled surface. It transfers heat really well, and while I think it could be a bit thicker and tackier, I have no real complaints about its performance."

"When I first saw the tube was only 10 grams, I considered buying multiple, but one tiny tube turned out to be more than enough! I ended up adding heat sinks to all sorts of gadgets in my house. The paste is amazing for creating permanent bonds, although I wouldn’t recommend it for parts you want to disassemble later. I’d describe this product as a 'thick super glue meant for moving heat on electronics.' It dried faster than I expected, fully sticking in about 2 hours after cleanup, and I doubt anything will pull those heat sinks off after sitting overnight."

"I used this to glue some large heat sinks to an LED array's aluminum panel, and it worked great. The light runs much cooler now, and the heat sinks get hot, so it must be transferring the heat. Better than thermal grease if you want your heat sink to stay in place permanently."

"I’m currently bonding a metal temperature sensor to an aluminum resin tank on my 3D printer with this thermal glue. It works well for attaching components to surfaces and transfers heat effectively. Although it took longer than expected to firm up, I would definitely recommend it for any heat conductivity needs."

"I used it to mount a heatsink on an RC car motor, and the hold is strong and reliable. It's been a couple of months, and everything is still in place, which is impressive!"

"I find this stuff to be excellent; it works just as well as vintage silicone heat sink compound. The functionality and consistency are nearly identical to what I used decades ago. I plan to use it for everything from power transistors to CPUs. Highly recommended!"

"After my old Arctic Silver thermal epoxy dried up, I decided to try this product. To my surprise, there’s a negligible performance difference at a fraction of the cost. This will definitely be my new go-to choice!"

"This glue does a fantastic job of securing heat sinks to components that need heat dissipation. While its thermal conductivity isn't as high as typical CPU compounds, it provides a thinner layer than thermal adhesive pads, improving heat transmission. Plus, the tube is quite large and has a 24-month shelf life!"

"I love the high-quality materials used in this product. It feels durable and looks great!"

"The comfortable fit makes it perfect for all-day wear. I can’t get enough of it!"

"This product is not only stylish but also offers good value for money. Definitely worth it!"

"I used this to repair my back glass defroster. It worked perfectly! I cleaned the contact areas and applied the Silver Glue. After checking with an Ohm Meter, I was thrilled to see successful conductivity! The paste is thick enough to stay in place, and while it wasn’t fully dry overnight, I’m optimistic it will harden soon. I’d definitely purchase this again, though I wish it had English instructions."

"I had higher expectations when I bought this, thinking it would be strong. However, I found it to be more like paint. It took quite a while to cure, and it didn't feel strong enough for my needs."

"I appreciated the precision of the applicator, but the conductive ink failed me repeatedly. I was using it for some old Xbox modifications, which require careful bridging. Unfortunately, it spreads too much and doesn’t create a reliable connection, which is incredibly frustrating. Removing it is also a hassle."

"I bought this for my friend's bass because it seemed extra noisy in single coil mode. After applying the tape, I didn't notice any significant change, but I'm sure the copper foil is working fine. Just don't expect magical silence if shielding wasn't the issue. The price is great, and I have plenty of tape left for other instruments."

"This tape is a fantastic value! It's a bit thinner than aluminum tape from home improvement stores, but it has impressive strength thanks to the plastic backing. It peels off easily, and I'm really impressed with the quality for the price I paid."

"I used this to shield my guitar completely and had more than enough material for the job. It was easy to manipulate and apply, and the adhesive was strong and conductive. I found it perfect for my needs, and I’m quite satisfied with the outcome."
