J-B Weld 50133 Plastic Bonder Structural Adhesive Syringe - Tan - 25 ml

I cannot say enough good things about the J-B Weld 50133 Plastic Bonder! I needed to repair a cracked ABS plastic panel on my car and a broken PVC trim piece around my house, and this adhesive exceeded every expectation. The syringe design makes mixing the two-part epoxy so easy—no messy measuring, just squeeze and go. It set in under 6 minutes like the label says, and after letting it cure for an hour, the bond was unbreakable. I tried prying the repaired pieces apart and they wouldn’t budge at all! What I love most is how versatile it is. It worked perfectly on flexible and rigid plastic, and even filled small gaps seamlessly without any extra filler. The tan color also blended in nicely with my project materials, so the repair isn’t an eyesore. At under $7 for a 25ml pack, it’s an incredible value too. I’ve gone through cheap plastic glues that fail after a week, but this J-B Weld bonder is built to last. Whether you’re a DIY hobbyist or tackling household repairs, this is a must-have in your toolbox. 5 stars all the way—will definitely buy again!

The **J‑B Weld Plastic Bonder Structural Adhesive Syringe turned out to be one of those “why didn’t I buy this sooner?” products. First thing I liked is the dual-syringe design, which dispenses the two components in a simple 1:1 mix ratio, making it easy even if you’re not a DIY expert. Just squeeze, mix, and apply—no complicated measuring required. I used it to repair a cracked plastic piece, and it worked surprisingly well. The adhesive sets in about 15 minutes and can be sanded after around 30 minutes, so you’re not waiting forever for it to cure. What really impressed me is how strong it becomes once cured. With a tensile strength of about 3770 PSI, it forms a tough, permanent bond that can handle plastics, composites, metal, and even concrete

Easy to use and has stood up to more than 3 months of use! I was worried that this would not plastic to plastic bond as well as I needed. But so far it held up to 3 months of use through winter. Next test will be the heat of Utah summer! The color isn’t my favorite, but it definitely has the holding strength I’ve needed. It’s super easy to use and mix, and the cap has done its job to keep the unused portion useable for future projects. The drying time was just fine, seemed to work quickly enough to not have to worry about keeping it steady for days, but it had enough workability time to allow me to get my project in the correct position before it set.

I tested this glue and several others on polypropylene. I used the lid of a disposable coffee cup, which had "5" in the recycle symbol indicating polypropylene (pp). I did not sand the surface to rough it up. I used a drop of each glue to attach a metal nut (as in bolt/nut) to the flat plastic surface and allowed 16 hours to cure. * JB Weld Plastic Bonder (this item). Peeled right off, adhered moderately to metal nut. * Testors model cement. Peeled right off, did not adhere to metal nut. * Gorilla Glue. Peeled right off, adhered moderately to metal nut. * Bob Smith Industries slow cure Epoxy. Peeled right off, adhered well to metal nut. * Contact cement. Adhered moderately to polypropylene and to metal nut. Adhesion depends on size of surface area. * Super glue. Peeled right off, adhered well to metal nut. * Construction adhesive (Fuze-It). Peeled off of polypropylene easily. Adhered moderately to metal nut. * Hot glue. Adhered moderately to polypropylene and to metal nut. * High temperature hot glue (Steinel GF 260). Adhered well to polypropylene and to metal nut. * 2-part superglue and accelerant (Loctite Plastics Bonding System). Adhered well to polypropylene but only moderately to metal nut, fairly easy to separate, probably requires larger surface area contact. Only contact cement and hot glue produced a good bond of metal to polypropylene. Contact cement is only as strong as the latex itself so I was able to stretch the nut away from the polypropylene with a little force. Hot glue gave a stronger bond, though with more force I was able to break them apart. High temperature/high performance hot glue stick formulation held well and required significant force to break apart. This also has the benefit of filling gaps if that is a requirement. This seems to be the best option, though I don't know about longevity of the bond. Untested were polypropylene formulations of hot glue (SuperTac 500 or Tecbond 263) because of cost and availability.

Used as directed and it will outlast most things you will use it on. JB makes a wide range of epoxy products, and I have yet to be disappointed in my results over decades of use. While not all plastics can be bonded with consumer grade glues, this is the best of choice for most versatile. Have used to repair cracks in auto body bumper covers, build antenna section joiners and insulators, indoor and outdoor plastic to other surface settings, etc. Temps here range from single to triple digit, wind speeds up to 70mph gusting over 90mph on occasion, and hailstones from pea to grapefruit size (Think tornado alley). Weather and use have broken some of my strucutres, but not the JB bond itself. HIGHLY RECOMMENDED.

I use this to bond 3d printed pieces together. It works great. It doesn't dry as quick as superglue but the bond is far superior so it's a worth-it trade off.

Worked great for the plastic project I was doing

Very strong glue that sticks to almost anything

Très satisfaite de ce produit car avec le système de fermeture ne sèche pas et dure

El mejor con diferencia

Amazing product as it perfectly worked for my car bumper misplacement. As expected Aramex delivery service is pathetic in my area and customer service doesn't bother to respond to my calls

Used esun white PETG to make some dedk top shelves and this stuff worked great is a little yellowish in color but not noticeable in thin layers with this white. It hardens in under an hour, is almost hard in 25 to 20 min and cures rock solid and impact resisrant in about 24 hours. Rhe stuff I bought did anyway and am quite happy with the results.
