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

Rarely does a situation present itself that calls me to leave feedback; usually goes one of two ways (utter disappointment, exceptional awe). This gets a two thumbs up from me, I used plastic bonder on a non original tab I used from something random. Not only did it survive my use my chain snapped at 12,500 rpm destroying everything in its path. It did break the tab off, but not where the applicator was… which should tell you this product is mind blowingly durable and strong. License plate used as reference to show how much wreckage my chain created yet this product did not budge, the tab broke in an entirely different place! Easy setup, superb holding power, thickness as you desire per your needs. 10/10 the last picture shows how it held the piece I fabbed up, just amazing stuff!

I had a plastic door break off at the tab that holds the door onto the storage cabinet. I tried Gorilla Glue because that stuff is great but apparently not meant for hard plastic. This stuff worked like a charm. I was wondering what to use to mix the two substances together but, wow, there was a small wooden stir stick inside the package. I like that you can cap it and save it for future needs. Very decently priced.

This JB Weld Plastic Bonder is amazing stuff. Got it to fix my boyfriend's work van interior panels that had multiple cracks and chips on the edges. And this stuff worked amazing! It's so easy to mix because the applicator dispenses the precise ratio at the same time. Just mix mix mix and apply. It hardens and attaches the parts beautifully. You can't even see where the cracks were and it formed and filled in the chips perfectly. I am really impressed with this product . I highly recommend. You will not be disappointed.

This is my current favorite epoxy for plastic. Some application tips (my family has some background with structural adhesives, forgive me if I geek out).If you are using this for a structural repair (i.e., plastic piece broke because it was under stress, it will be under stress again, and you want to make a repair stronger than the original piece):* Test fit the broken pieces together before you start. (If the pieces will move in use [ex. laptop hinges], make sure that any built-up areas of your repair will not interfere with the operation.)* If you are able to reinforce the plastic joint with a piece of metal, do that - this epoxy makes an excellent bond to metal. (You could use a short section of wire coat hanger bent to fit, for example, or a strip of aluminum cut from a beverage can.) In many cases the combination of plastic + reinforcing metal + epoxy will make a lifetime repair. Bridge 'across' the break (highest-stress area) with the metal, and bend the ends of the reinforcing piece so they are physically 'trapped' by the cured adhesive. (Think of the little ribs on rebar which provide a physical bond to reinforced concrete.)* Clean the plastic parts and any reinforcement pieces using 91% rubbing alcohol (isopropyl) on a clean cotton swab and let them dry thoroughly. Surface preparation is *extremely* important with any epoxy. After cleaning, do not touch the bonding surfaces with your bare hands.* Roughen the plastic bonding surfaces ("key" the surface) using sandpaper, a small file, or an emery board (or you could even scratch small grooves into the plastic with a scalpel or knife blade). Think of a climber scaling a smooth rock face - you want to give the adhesive some 'handholds' at the microscopic level - something to physically grab onto. Clean the parts again if appropriate.* Mix the two parts of the epoxy in a 50/50 ratio. I use a piece of cardboard cut from a box as a mixing board. If the plunger gives you more of one part, discard the extra - get equal size extrusions of both parts lying next to each other on the mixing board. (If you try to mix a tiny amount, it is easier to mess up the ratios - go ahead and lay down a minimum 1-inch strip for example.)* Mix the two parts *thoroughly*. This includes dragging your mixing stick against the mixing board, because it will have a big glob of one or the other parts on it. Look for a uniform color before applying the mixed epoxy. (If the two parts aren't mixed thoroughly in the proper proportions, they cannot work correctly.)* Apply the epoxy to your parts, making sure to coat all the bonding surfaces.* Tape the parts together, or hold them in place using clamps or weights. (Don't force all of the adhesive out of the joints.) Be sure there is no adhesive where you don't want it, and also be aware that it will 'flow' to some extent. Then set the parts aside and *leave them alone* overnight (the epoxy will harden relatively quickly, but it will continue to gain strength for longer - remember we are doing a critical structural repair). Resist the urge to poke at them and examine them during the critical first minutes of the curing process.* Once the initial application of epoxy has cured, you are encouraged to apply more epoxy to fill in weak areas or to completely cover your metal reinforcements. Note that this epoxy will 'foam up' or swell very slightly (think of polyurethane insulating foam for windows, but on a much smaller scale). When repairing/reinforcing plastic, look for 'stress risers' - usually the plastic will break where there is a 90 degree bend for example. Cover over these areas with a fillet of the epoxy. You can even run 'beads' of the epoxy to add reinforcing ribs. More surface contact with the plastic is better, and be sure to clean and key all the bonding surfaces. If you can bridge across a broken joint completely to enclose it, this is excellent (since we now have a new epoxy 'structural member' rather than relying on just the 'shear strength' of the adhesive).General guideline: Any two-part catalyzed product (like this epoxy) will be miles ahead [technical term] of any one-part product.Pro tip: Say "cure" (not 'dry'). Say "adhesive" (not 'glue').

Great product! Have used JB Weld products for decades and they are always reliable. This plastic weld did not disappoint. Used it to repair a small post that holds a side cover on a motorcycle. Obviously buying a new one would have cost a lot of money. This made it like new for a few bucks. And there is plenty left over for future jobs.Easy to mix and apply. I put it on a little thick for the small area and it took more time to cure. Once it did, the piece is as strong as original.Only caution is on first use, squeeze out the first bit and discard. See photo. Then squeeze the portion for your job. The first portion will not provide a good 50/50 mix.JB Weld has never failed to perform for me.

Wonderful glue
