J-B Weld ClearWeld 5 Minute Epoxy, Clear, Syringe, 2 Pack, 50112-2

It works, what more can you say?

We used this to seal a tank on our camper. Worked great and sealed the leak

This has been my go to epoxy for years now. Sets quickly and a great bond. Recommended!

Two tubes for less than at Wallyworld.

Is really strong, I used to put some bathroom appliances, the only problem is that is too liquid initially. Your probably need to use some soft tape to keep things in place while it cures.

Got this to fix some plastic toys and it worked great. It worked so great that I had to break the toy to get it unstuck from my work table

I see a few reviews complaining about the container being leaky and others about the cap welding shut. Its a syringe. Both of those problems are solved by pulling the syringe back up after you push out what you need. The remaining liquid is drawn back in and does not mix. I honestly think their packaging is fine and nifty, but I have to agree that perhaps they need to improve it if a large portion of their consumer base has difficulties with it. Additionally, as long as you have applied pressure to the center or entirety of the syringe, equal amounts have to come out of both sides, even if one side comes out first because it is more fluid. I suspect some people pulled the syringe away before it was finished releasing. One side is clear and the other is yellowish, and they settle into semi-circles so you can eyeball the amount if you really feel you need to. In summary, I didnt have issues with mixing at all. The epoxy definitely set around 5 minutes. It is hard to get a very small amount out of the syringe, but the smallest amount I could get out was enough for what I needed it for. It set quickly enough that I hardly needed tape to hold the pieces of broken porcelain together that I was adhering. The downside was I didnt get to wipe off some of the excess because it set in the time it took for me to finagle some of the final pieces in. For a porcelain/ceramics job, it works well. I cant speak to any other material, but I do believe the mixing is going to be the same across the board. I think it is important to highlight, like a couple of others have, that the epoxy is still tacky after several hours and should be probably be left to cure for a good 24 hours.

Great stuff. Insert on the face of a $269 putter came off and couldnt find it. Filled the recess on the face of the putter with this epoxy, sanded it perfectly smooth, and am rolling putts as if the putter was never damaged. Saved me a ton of money!

I’ve used this for a modern ‘Kintsugi’ style porcelain repair, with satisfactory results. I wanted to repair a chipped old bowl to reach a Kintsugi style repair while using modern accessible materials. I decided to try the combination of epoxy and golden colored mica powder. I mixed some powder with the epoxy and applied it in small quantity on the chipped part. I had to factor in the epoxy viscosity, gravity and the relatively quick setting time to get a nicely rounded and smooth patch. At first I didn’t like the gold effect produced by the mix of mica powder with the clear epoxy, so I decided to sprinkle more powder on the surface of the epoxy patch a few minutes into the process and after it started setting. This gave it the desired finish I was looking for. For this type of application I would recommend this product.

I’ve used JB Weld products with great success in the past. I was looking for one that would bond a brass to a aluminum bar as a very temporary fitting rather than tapping the brass cylinder out. Just something I could use long enough to put a little torque on it and turn it one turn. It was a 60 year old hot water pressure valve fitting that’s the intake to a faucet that seals had finally given out. I just wanted to get one turn out of it without going into a full tap set with a microscopic amount of space to put as a place to join something. Anyway, I did everything right. Sanded it down, mixed the compound properly and so on. Applied properly and then tried multiple methods of random bits to fix to it, if only temporarily. Nothing at all would stay, it left with a gummy, weak bond that never really seemed to cure. Maybe too much humidity, or the pipes latent heat was too much for its specs, but according to the specs all of that was in the realm of both applications, use and environment. So sadly to say, this one is less useful that dollar store super glue, at least if you’re in a *mildly* hot and humid environment. Most adhesives I’ve used work in that type of environment without any issue. I even gave it two days to bond before touching it, still the same gummy meh bond. Its maybe useful if you’re sanding down two large flat squares of plastic or wood and sticking them together inside a vice with this and then putting in screws for a permanent bond. Sure, maybe it would work then. But then what’s the point of getting something like this? Any old adhesive would work for that.
