J-B Weld 8276 KwikWeld Quick Setting Steel Reinforced Epoxy - Dark Grey 2 oz

I got this to try and fix a hinge on my MSI laptop, which had suddenly given out one night when trying to close it (apparently that's a thing those computers are notorious for). Because of how the hinge was set up, I couldn't open or close the computer without the LCD screen trying to peel itself off the computer frame, which was always horrible to see. I used a C-clamp to keep the screen attached the frame, but that kept me from being able to actually close the laptop, effectively turning it into a small desktop computer. This wasn't super convenient and I needed to be able to pack my laptop for travel, so I decided to try epoxying the metal components of the hinge to the plastic of the frame to see if that would keep it together enough for me to able to open and close the computer without further damage happening. I had low expectations for how well this stuff would work, but I was on a time crunch and this was the most promising stuff I could find, so I gave it a go. I mixed it according to instructions (it has a bit of a funky chemical odor at this stage) , then quickly applied it inside the hinge to bond the metal and plastic. Then I used my trusty C-clamp to firmly keep the parts together while the epoxy cured. I left it like that for 24 hours (I think it normally takes 6 hours, but better safe than sorry), then gently removed the C-clamp. When I tried closing my computer.... it worked good as new! Literally, that hinge is sealed like a rock. It feels as strong as it did before it suddenly gave out. I also wiped off the excess epoxy while applying it, so while a little bit is still visible around the seams of the repair site, you'd never know it was there. No odor now that it cured, too. It's been about two weeks since I made the repair and the epoxy is still holding strong. I am not sure what else I would ever need to use this stuff on, but for small oddball repairs like mine, it was great. I'm confident that my laptop's life has been extended significantly, and if the other hinge goes out, I know exactly what to do. I never thought I'd get excited about epoxy, of all things, but believe me, this stuff is 100% worth it. Read more

A Must-Have Repair Epoxy That Actually Holds I’ve used a lot of different adhesives and epoxies over the years, and this J-B Weld KwikWeld stands out because it’s both strong and easy to work with. It mixes smoothly, sets up quickly, and once cured it feels as solid as metal. I tried it on a small crack in a metal bracket and also on a plastic piece in the garage—both repairs have held up under stress. The quick set time means you don’t have to clamp things forever, but you do have enough working time to position parts properly before it hardens. One thing to keep in mind: once it sets, it’s not easy to undo, so make sure you’re precise in applying it. Also, while it bonds to many surfaces, for best results a clean, roughed-up surface makes a huge difference. Bottom line: A dependable, steel-reinforced epoxy that’s perfect to keep in the toolbox for quick, long-lasting fixes. Read more

I have a nice drinking cup i use for my tea. it's aluminum, and 1 liter. I thickened the handle to include a wood and leather grip, and have been happily sipping tea for years with it. The other day I accidentally knocked it off the counter and onto the floor. And the top part or the handle popped loose. Since i don't own an aluminum spot welder, I went looking for an epoxy that handled both heat, and aluminum well. I settled on this product as being something simple, easily mixed, easily applied and purported to be able to do the job. This was not my first rodeo with epoxies. I've been using them for years. But it was my first with aluminum, which is often tricky to deal with due to the oxidation layer creating a weaker bond. Preparation was necessary, which mostly meant sanding the crap out of the surfaces being bound. That removes the oxidized aluminum and gives an otherwise polished surface some roughness for the epoxy to grip. Following the instructions, and knowing about how much I'd need, I mixed an appropriate amount, applied it to the surfaces, then used a couple of rubber bands to hold it in place. It began to set fairly quickly, so if you do use it, be ready to apply it as soon as it's mixed. It says it's a 6 minute work time, and I'd say it's probably closer to 5. Having had epoxies set up quickly, I was ready for that possibility. I let it cure overnight, and in the morning, I had my tea as usual. The bond itself is fairly secure, with no apparent wiggle. The epoxy had a slightly soft texture at first as it set, but over time that's hardened up nicely. So, if you have aluminum you need bonded, I know this will work well, with the proper prep and after waiting the full cure time before messing with it. Knowing HOW to use an epoxy is most of the battle, so follow the steps and give yourself time for things to set and you'll love this stuff. Read more
