Plastruct Plastic Weld w/applicator 2oz Bottle

I do some musical instrument repair work for friends sometimes, and a friend of mine brought over a wireless microphone that had gotten dropped and stopped working. Turned out to be a broken, plastic battery holder. The Plastruct Plastic Weld stuff saved the day!! This stuff is AMAZING!!! Where has it been all my life?! It's not a glue. It literally, chemically melts/fuses the plastic parts together, which forms a super strong bond. It's as if it was never broken or cracked at all! I've never seen anything like this, but have always thought it would great if something like this existed! And, now it DOES!! I love it!Procedure:I made sure the surfaces were clean, then brushed some of it on with the built-in applicator brush, quickly lined up the broken parts, and pressed them together for about 30 seconds. Then, after about a minute. It was pretty well bonded at that point, but I brushed a little more all around the seams, and pressed and held it for another 30 seconds for an even stronger bond. You can actually see where it chemically reacted and fused the plastic together! Amazing stuff! And, a little goes a long way, because it has a capillary action, whereby it creeps into all the gaps by itself. I'm going to get SO much use out of this! I'm super impressed!You can see in one of the photos where there's a white-ish bead around the seam where I used this stuff in the battery compartment of the microphone.One word of caution though; Make sure you use it with plenty of ventilation, and consider using some nitrile gloves. There is a cancer warning on the label, as well as warnings not to sniff it, or get it on your skin. I wore a mask, nitrile gloves, and had my workbench fan on high. I didn't smell anything, and had nothing on my hands. Being safe and taking care of yourself is a good thing.I HIGHLY recommend this wonderful stuff!!

When used on appropriate materials this product creates strong bonds that "glue" can't duplicate.

I bought this Plastruct Plastic Weld specifically to assemble a bridge model (see attached pictures) since it was molded in black ABS plastic. All my other glues/cements on hand were geared toward styrene or were cyanoacrylates.And the model manufacturer explicitly recommended "Plastruct Plastic Weld" by name in their instructions.So imagine my surprise when the Plastruct Plastic Weld didn't hold the delicate parts together (not after a few seconds, not after minutes). The delicate pieces would just flopped over under their own weight when released. I might as well have been using water.So in frustration/desperation, I fell back to some on-hand Tamiya 87038 (an excellent product for its primary intended purposes) to assemble the first of the two bridge sections. But it was a long painful process as the parts "welded" very slowly and not very strongly with many repeat attempts.Then a light bulb went on "Read the instructions of the Plastruct Plastic Weld bottle" (the recommended step when all else fails). But alas, still no joy there either as it didn't say anything that I hadn't already tried. And it just reinforced that it was indeed intended for ABS and should be working.Then the second light bulb went on, "SHAKE IT UP". Bingo! The pieces bonded sufficiently in mere seconds where I could move on to the next piece quickly. I assembled the second bridge section in a tiny fraction of the time of the 1st one using the now-shaken Plastruct Plastic Weld. And the fully-set welds the next day were much stronger than those of the 1st bridge (which I subsequently went back and fixed up with Plastruct Plastic Welds).The Plastruct Plastic Weld also was easy enough to apply and it flowed well into joints via capillary action.The only real negative I encountered was that the in-bottle brush is quite fat. And although that somewhat depends on what you are welding, this is intended for scale model assembly after all. So it seems WAY too big (particularly in contrast to the excellent very-fine point of the Tamiya in-bottle brush). After all, I'm not trying to weld black ABS pipes for my house's toilet lines. For that, I go to Lowe's and get some Oatey's.I decided not to take away any stars from Plastruct Plastic Weld for not including SHAKE BEFORE USE in their instructions/label although I was really tempted. This may be the issue behind several of the negative reviews that I have read about it being ineffective. So please, Plastruct, update your label.

Had trouble sticking plastic together and the cap broke when someone knocked the bottle over. Was a bit disappointed.
