Plastics: Bonding System

Tried SEVERAL products in an attempt to glue together broken plastic toy parts. The ONLY one to "fuse" the broken pieces together was the Loctite Super Glue Plastics Bonding System. Even plain old Loctite couldn't get the job done.

Comes with a little sharpie-like primer that you just glide along both edges, and the tube of glue itself, to be applied to only one edge. BE SURE TO USE PROTECTIVE GLOVES. I used ordinary, very thin vinyl ones available for cheap on Amazon. The glue won't hurt you, it's just that it's very difficult not to get it on your hands, dries immediately, and takes at least 24 hours to get it all off if you keep picking at it. Better to get the gloves and avoid that problem. I used it to glue together two panels at the bottom of my car driver's seat: the power seat-control panel on the side, and the adjoining one on the bottom front. I glued two little pegs inserted into holes, plus the seam where the panel meets the front panel. I had to do this because the rear panel at the back of the seat is missing, which normally holds everything in place, so the entire assembly was hanging down. Now it seems to be holding pretty solidly. I glued them together about three weeks ago. I'll give an update in if and when it ever comes apart again.

It's hard to find glue that will work on every plastic, and this one doesn't. BUT, it works on most of the plastics I have tried, including ABS. I did have a problem with PVC, but I guess that is why they make PVC cement. For most plastics, this product works for medium duty applications.

I've used this before, but when I needed a fast glue recently, my old tube was hardened, so I bought these. The glue works great and gives you just enough time to get pieces in place before it hardens. Unfortunately, if you don't use the whole thing fairly quickly, it'll harden and be unusable. That's why this set of six is so handy - if I through one away, I'm still good to go...

)Save your money - does not work, at least not reliably. I tried to use it to repair a broken watch band loop. It's made of a thick rubbery plastic that seemed like the ideal application for this glue. The break was fresh, the rubber was clean, directions were followed, and the result was a bond that failed within 24 hours. Perhaps there is something about the material these watch bands are made of that makes them incompatible with this glue, but the list of things it's supposed to work on would give you he impression that shouldn't be the case. In any event, unless your a trained chemist specializing in synthetics, you're likely not going to know one plastic from another and which glues are compatible with which plastics. Also, as many users noted, consider this a single-use product, possibly two times if you're lucky. While there is plenty of glue for multiple repairs, the nozzle seals itself once exposed to air in spite of the cap being securely attached. At that point, you can get one more application (assuming you think you have something this will work on) by puncturing the metal tube with a needle or push pin. I had enough of the 'primer' for at least two repairs had I elected to try to use it again, but I don't know how much more beyond that. Even though you can't return this (hazardous material handling required), Amazon made good with a refund anyway, so kudos to them for continuing to maintain a relatively high bar for customer service. Addendum: One thing I forgot to mention is that Amazon carries replacement strap loops - they run around eight or nine dollars. Pretty expensive for no more than they are, but still cheaper than a whole new band. In lieu of that, after the glue failed, I went with a 79-cent o-ring from my local Ace. It may not last as long as the original or replacement band loops, but they're easy to put on and I can several for the $8 it would cost for a replacement loop, not to mention the cost of a new band.

The good: the cement works very well. It's easy to apply, and the activator's container is brilliant -- it works like a felt tip pen. Wipe it over each contact surface, wait a minute, apply the glue, and you're ready to go. The bad: the glue tube's cap was defective or badly designed, and unusable. You're supposed to screw the bottom part onto the tube, breaking the metal diaphram that seals the glue in; then twist the top part off to apply the glue, and twist it back on when done. As I tried to screw the cap onto the tube it tilted to the side, and the more I tightened it the more it tilted; no amount of fiddling or force would make it engage the threads and go on straight. I threw it away and put a piece of plastic wrap over the mouth of the tube, and fastened it with a rubber band. That probably won't work; the next time I need the glue it will be dried out, and I'll have to replace it. Next time I'll look for a product as similar to this one as I can find, but a different brand.

Pros: It did work. I had broken plastic on this diskette drive for a Compaq Armada 4120. The plastic that keeps the drive in the machine was broken. This stuff is very effective if you're careful. I can still replace the drive if needed. Step 1 is super easy. Cons: The Citizen W1D in the plastic housing is a paperweight. Ok that's not the plastic bonders fault. The glue in step 2 will stick to your fingers if you're wreckless. It's very hard to remove. Make sure you seal the glue tightly or you're cutting the container open. The repair job is not pretty. Final thoughts: Follow instructions carefully and you'll be fine. Seal everything tightly when done using. The pen seemed dry but it still seemed to work with the minimal amount that came out.

I used this glue with primer to attach a Teflon slider on a rubber soled curling shoe. Been using it for two months and so far so good. Very difficult problem to solve as Teflon is very slippery and nonporous.
