J-B Weld™ Syringe Original Cold-Weld™ Two-Part Epoxy System, Ultra-Fast Setting Time, High Strength, Suitable for All Metals and Other Materials, Dark Grey 25ml

great stuff, sticky and messy to mix, impossible to make this stuff look nice but that isn't the point. Sets rock solid

This stuff is amazing, bought several things to fix a cupboard hinge fixing and nothing worked , would have involved buying tools for just one job or a whole stretch of wall cupboard in the kitchen. And this popped up. Absolutely perfect fixed and held the hinge in situ ...life saver and wallet saver. Door has been up and working on the cupboard over a month now and being used several times a day.

Use to repair / plug hole in lawn mower deck. The deck of the law mower had rusted through in places and I used this as a metal filler to plug the holes after I cleaned them up. Seem to have done the job.

There is an error in the product picture, which contains an incorrect strength figure. I attach the correct photos of the packaging. The same information is verified with J-B Weld web site. Refer to their web site for safety info, the product is reasonably safe. I also include photos of my project with this product – a hinge bonded to Ni-Ti metal of Flexon glasses. The strength figure 5020psi is about a lump of cured epoxy being pulled apart. Its bonding strength is lower, somewhere about 3000psi for steel, 2000psi for aluminium, both degreased and roughened, less for plastics and glass. This means that gluing two parts together, it makes sense to also spread some of this product on the adjacent to the contact area, thus increasing the bonding area. It is not mentioned for this particular product, but similar epoxies bond up to 25% stronger if cured at about 40C rather than room temperature. This epoxy thickens slow, within 4-6 hours, and then gains strength throughout the following 15-24 hours. So, give it time to develop. I would not trust the marketing statement about 550F (288C) temperatures, because it is probably not its Tg (glass transition temp, almost complete loss of "strength"), although who knows! Most epoxies have Tg around 60C-80C. It would be interesting to find out Tg for J-B Weld original! The only negative is its colour - clear epoxies look more tidy. Great product, I used it in the past with great success.

Dead easy to use, takes a while to dry but works fantastically. Rock solid when dry.

Absolutely brilliant, fixed my kitchen tap by bonding two small pieces of metal (super glue had failed). 10/10 strength and application.

This stuff is really good. I was a bit dubious at first as it’s quite loose when it comes out of the syringe and stays the same on application which, to be fair, helped me out. It stayed sticky for hours afterwards causing me to think it isn’t set properly or my mix want correct. However after leaving it overnight it solidified into a really strong bond which hasn’t budged since. For reference I used it to repair a broken weld on a bar stool frame.

I was wary with this product as I usually use Devcon, but that carries a premium price now, so I gave this a go. It mixes easily if not a tad too wet, but given time it thickens and sets. Setting time is best left overnight, but I can't knock it. Has worked well, and has proven to be sandable. Nothing gets 10/10, but this is a solid 9/10. I used it btw on a model with 50 yr old plastic, and on mounting ski bindings.

Não colou a bola do meu câmbio e ainda ficou cinza, cara de sujeira.

This epoxy is perfect. I use it to weld pinbacks to enamel pins. It's so sturdy. Even with the expensive shipping to the Netherlands worth every penny.

Hält das was versprochen wird.

Un buen producto, mucha adhesión. Fácil de usar
