LoctitePlastics Bonder Bonding System, 2 Gram & 4 Gram Tubes, 6 Pack - Clear Superglue for Plastic, Wood, Metal, Crafts, & Repair, Instant Glue Adhesive, Quick Dry

NOT ALL PLASTICS ARE ALIKE!! This glue IS for Polypropylene type of plastics. IT WORKS!!!! DO NOT GET IT ON YOUR FINGERS!!! IT WILL BURN LIKE MOLTEN LAVA!! (ask me how I know :( ) I was making a rain visor for my mail delivery vehicle with corrugated plastic panels. This was the ONLY glue that worked!! And it "welds" the pieces together to give you an amazing bond! So if you're working with PE, PP, or PTFE, this is your answer.

I bought this to repair a weighted action lever of a synthesizer keyboard key that had broken. It was made of nylon, and nylon does not glue. The repair was a polished steel weight that had been overmolded with nylon and had broken where the two materials came together. I used this bonder by coating both parts with the activator then applying the bonding adhesive , clamped them gently, and left them overnight. Next morning, good as new. These weighted action parts are both expensive and unobtainium at this time, so my musician friend was ecstatic. Time will tell how long this will last in usage so we put this part up in the highest note on the keyboard under the assumption it would get infrequent use giving it the opportunity to last the rest of the life of the instrument. If I owned this myself, I would have left it mid keybed where it will get hammered all the time just to see how durable it really was. Time will tell. But the product did exactly what it claims and I am glad to be adding this product to my "glue" collection.

I've used Loctite adhesives for years, for all sorts of stuff. I'd avoided trying to stick two dissimilar plastics together up to now, but I had a project that really needed it to happen. So, I spent some time looking at/for some options, and there were few. This Loctite system appeared here, so based on the fact that Loctite hadn't let me down yet, I tried it.Folks, this stuff really works. If you follow the directions precisely as written onm the back you'll have good luck. I did. After I got my lil project finished I tried it on a few more different types of plastic, and of the four I tried, all four worked. All stuck to all. No, I'm not promising your plastic'll glue up, but mine did. YMMV, IANAL,GLWT.Anywho, I'm pleased with the results I got. It did what I needed, and then some.I gave this a 4-star review, not because it disappointed me, but because it didn't. I reserve that rare fifth star for those exceptional things that really deserve it. Four stars is my typical best, and I rated this 4 stars because I expected Loctite to work, as it always has for me, and it did just that, on plastics you're unlikely to stick together with other stuff.I'm not employed by or or otherwise related to Loctite, nor do I receive any sort of compensation for my reviews. I do 'em because I oughta, and because I'm not gonna BS y'all.

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.

)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.
