3M Super-Fast Repair Adhesive, 04747, Tranlucent Color,Two-Component, Semi-Rigid, Urethane Adhesive, 47.3 mL/1.6 fl oz Cartridge

I’ve been using 3M products for decades, and have come to trust their claims for the their products’ ability to work on plastics with which other brands’ products fail miserably. This adhesive and the results I’ve gotten from it strengthened my trust in 3M’s products. I used this adhesive to glue a backup sump pump made of polyethylene to a pvc pipe, and after a minute of applying the combined adhesive and holding the work parts in place, the adhesive set to a semirigid consistency that was strong enough for me to let go of the work pieces. I left the parts to cure overnight, and they came out strong and solid with no sign of the adhesive peeling off the polyethylene or the parts coming apart. The parts were solidly glued to each other. All this was after trying a dozen other types of adhesives ranging from plumbers solvent adhesive for pvc to plumbers general adhesive for multiple products (abs, PVC, CPVC), to plumbers “fusion” adhesive for dissimilar plastics to other brands’ adhesives and epoxies specifically for plastics. They all failed —all peeling easily off my polyethylene parts. The only con of this 3M product in my opinion: the work time coming out of the mixing syringe is only 20 seconds, so I had to work quickly to apply the adhesive to both mating surfaces, mate them together, and in my case with the pipe shape, twist the parts to spread the glue around—all within 20 seconds. Set time was about a minute as indicated on 3M’s data sheet for this product, so be ready to clamp or hold your work pieces together for a full minute. To maximize the chances of a strong bond, I did use sandpaper to lightly roughen up the polyethylene surface and applied adhesive primer for low energy plastics to it before I applied the adhesive. The cost of using this system is high compared to general purpose and specialty plastic adhesives from other companies: you have to have a 3M adhesive gun, and if you want to use the adhesive tube for more than just one job, you’ll need to buy extra mixing tips as the package only comes with a single tip. The adhesive tube itself is 2 to 3 times the price of other brands’ two-part plastic adhesives and epoxies. But this product actually worked for me when others have failed, so the cost was well worth it.

This stuff works amazing, i used this product to rebuild a bumper tab on my car that had broken. However make sure you work fast because this turns solid within a minute. Excellent product, very tough and durable in various environments and conditions.

Extremely fast curing time . Basically a one time repair item Due to one nozzle being supplied. For the price you pay two nozzles should be included. Excellent epoxy for repairing bumper tabs.

Excellent glue. Dry fast.

This is just about the handiest stuff I've come across in a long time. Here's why; It seems like I come across projects all the time where something needs to be glued (epoxy) but there is just no practical way to clamp it while the glue dries. With this epoxy, you can literally just hold it in place for 30 seconds and it's cured to the point you can let go. After a few minutes, you can actually use the part. I also use it to seal things, you can put pressure on it after a few minutes with no leaks (I've used it for low-pressure sealing of voids, only a few PSI. It's not technically a sealant). If this sounds good to you, I'd just make the plunge and invest in the gun and a pack of 50 of the nozzles. If you buy the nozzles in a 50 pack they are only about a dollar apiece. When you need this kind of epoxy there is often no other way reasonable get the job done and $1 seems like no big deal. I also have tubes of the 5 minute, 30 minute and the long set versions. With this quick set stuff, I don't see how you could use it without a gun and a nozzle, it just sets up too fast. With the longer set epoxy you certainly can mix it by hand and apply it with a popsicle stick or something. I still like to use the gun and nozzle because it mixes it perfectly and allows you to apply the glue right where it's needed. True, you do waste some epoxy that's left in the nozzle and you do use a $1 nozzle every time you epoxy something. But for the accuracy, times saving, and mess avoidance it's worth it to me.
