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

A Must-Have Repair Epoxy That Actually HoldsI’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.

This steel-reinforced epoxy sets in just 6 minutes and cures in 4–6 hours, making it great for quick repairs. With a tensile strength of about 3127 PSI, it bonds strongly to metal, wood, plastic, concrete, and more. It’s waterproof, paintable, and sandable, though not quite as strong as the original slow-cure J-B Weld. Perfect for fast, reliable fixes on small to medium projects.

My favorite epoxy! Note that JB also makes a similar product that comes in a twin syringe - that's most certainly _not_ the same thing. The 2-tube version sets up very quickly and is truly a 'kwik' epoxy. It's also very strong once cured.The syringe version can be convenient but in my experience it doesn't really set within the advertised 6 minute period. It remains somewhat rubbery for a long time.I 100% recommend the tube version of JB Kwik.

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.

I have used this product to fix many rings that i have bought, it works great when the weld comes loose on some of my statement jewelry that i wear. the repairs have lasted for years on some of my rings

Great product, I have used many times with great success.

I am retired and always tinkering with new projects and need adhesives a few times a month and this is my go-to stuff.I use disposable 30CC mixing cups (available here on Amazon) and reusable silicone stir sticks (also available here). I never actually measure the two parts, just sort of eyeball the amounts, and have never messed up the ratio. You can leave a little in the cup to see when it's fully cured. Use a little dab to secure an item in place or smear it all over to make it STAY. In 6 minutes or so, it gets firm and sort of hard-rubbery. I give it 24 hours to fully cure and then it's nice and hard. And shiny ultra-dark grey. Prep is a must, lightly scratching shiny or smooth surfaces. Always use alcohol. I use 70% medical pads by the bulk for this, but 90%+ would be better. I love this epoxy so much that when I am down to one package I order another as a backup just in case Amazon is temporarily sold out. About a month ago one of the hardener tubes had a tiny leak and my fingers got a little sticky, but that did not detract from the quality of this stuff.Once again, as long as you prep the surface properly, this is the best you can buy. 5 stars easy. Works on car/truck projects as well, just degrease AND use alcohol. (don't use this on hi-temp things... there are epoxies made just for that)P.S. You know how a cell phone charging cradle slips around on your night stand? A couple of small dabs of this epoxy on the bottom solves that problem.

JB WELD IS ALWAYS AWESOME. A FEW YEARS AGO MY SONS RACING BIKE HAD A HOLE IN THE CASING DURING A MOTO CROSS RACE AND I GOT IT SEALED UP IN TIME FOR THE NEXT RACE. IT SET UP ENOUGH TO SEAL AND LET HIM FINISH THE RACE BY WINNING. THANK YOU JB WELD :) LOVE THIS PRODUCT. EVERYONE SHOULD KEEP THIS ON HAND IN CASE OF EMERGENCIES OR AS NEEDED.
