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

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...

To make the below a long story short: As others have written the activator pen is dry. Further glued pieces didn't hold polypropylene to polypropylene. I don't know how much activator needs to be on the surfaces, but I went as far as taking to cap off and pulling out the material inside to try wringing it out and rubbing it in the surfaces. This seemed like I got some moisture out, and I noticed when applying glue some of it seemed to active turning hazy and some didn't the glue stayed clear. I bought acse and I opened 4 packages and none were very moist, I'm not sure if this is how moist it should be or not. As far as success I didn't have great luck. I was glueing cutting boards, polypropylene to polypropylene. It had a surface texture so the area I was glueing wasn't smooth, maybe I need a structural type epoxy for low energy surfaces, but this is much more expensive and harder to find. Anyhow, I was going to screw on rubber feet and I was working with a 1 inch slab, and when I went to screw in the feet the pieces I glued just separated. Luckily I had some appropriate sized sheet metal screws that were long enough to screw the feet and go in far enough to screw in the blocks the glued didn't adhere. Based on this I wouldn't recommend this product, especially for polypropylene and/or textured surfaces. Additionally you can't send it back since it's considered a flammable product. So looks like I'm out a few bucks.

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.

Does as stated, but quantity of glue is small for the money.

I had my doubts that this product would work as the plastic piece I was repairing was thin and delicate. This piece also, had to hold up a heavy rolled up curtain. I was not able to use a clamp so I anticipated that the glue would not hold. However, 24 hours later I was able to reinstall my curtain roller and the glued piece held the weight. I have to confess that I have not tried to roll down this silhouette for fear that the stress would cause the repaired plastic piece to fail. I am just happy that it is back up.

This is about the only adhesive system that can relaminate a ski bottom. Have some long metal edge cross country skis that ate30 yrs old. Tried to find 215cm skis but they don’t make them this long anymore, so used this to relaminated bottoms that were peeling back at tips and tails. Puts hundreds of miles in so far and all is good. Tried matine epoxy and otters rated for plastic, but only this 2-part system worked and saved me favorite skiis

The activator is like a marker with a fixed tip. I was expecting it to be a plunge tip to release more activator but it is not. The tip limits hard to reach areas and frankly would be better if it was like a brush tip. That said, I could recommend it if it was a spray or other form of application but due to its limiting design, I am disappointed with it. It made it hard to repair what I needed to because I only had about 5 mm max to apply it and could not spread apart further...it almost would require you to break the part more to apply. Also, when it does work, stay clear of offgassing when the two parts come into contact. the chemical reaction of the glue + activator offgasses a noxious smelling cloud that will burn your nose and eyes.

I bought the box of six. First one I opened the activator was 100% dry. NOTHING! I opened another one and that activator had some content (i could see it when I rubbed on paper). The actual bonding then appeared to work So if you manage to get activator on both pieces you should be OK... I have four left. Gluing plastics is very challenging.

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.
