IPS Weld-On 16 Acrylic Plastic Cement with 3 Pieces Weld-on Micro Tips, 5 oz Tube

I had a 22 year old 150 gallon Acrylic Aquarium that I reset up last May. After all the water and fish were in the tank I noticed one of the vertical seams was dis-bonding. It looked to be about 60% gone but was not leaking yet. After talking to a service tech from Weld On about the problem, I was advised to used Weld On 16. I cut a 1" strip of 1/8" thick plexiglass the length of the seam for a reinforcement pad. Weld On 16 has the consistency of maple syrup which was easy to apply to the 1" strip with an acid brush. Weld On 16 sets slow which is good if your a novice doing something like this. With the Aquarium full of water and fish, I held the strip in place firmly in place on the "outside" of the seam (not in the aquarium) for 10 mins (set time) firm but not so firm as to push out all the solvent. #1: the tank seam was not leaking "yet" and I do not think the solvent would work if it was. #2: do not try to wipe of the excess, you'll make a unremovable mess. #3: don't get the solvent on your fingers, you'll leave permanent finger prints on the acrylic. The tank seam never burst or leaked and the patch bought me time to replace the aquarium.

I used this product to weld a few pieces of acrylic together that needed to be water-tight. I had no trouble doing so. My only complaint is that Weld-On 16 has such a short hardening time that you are at great risk of clogging up your tips if you delay hardly at all between applications. I had to get out my exacto knife a few times to cut a sliver of the micro tip off to remove a blockage that formed within a minute or so of an application.To avoid this problem, I found that it helped if I watched to make sure the Weld-On sucked back down into the tube right after I stopped pushing on it. That is easy to make happen if you fully release the pressure on the tube because the tube then sucks in the Weld-On into the space it was just pushed out of.Overall, this is a great product. And, at least for me, the micro tips were included in the package.

Very good product. Could use twice the tips for this volume of cement applied in small amounts.

I had not worked with acrylic before and made a new dust cover for an old turntable. This glue worked great. It made a strong bond. It is a little tricky to use because it is kind of runny. But it needs to be to go in the seam to bond. Just practice on old pieces to get the hang of putting it on smoothly without spilling. Also leave the protective film on the pieces except around the edges you are gluing. It protects the surface in case you spill some glue. This stuff is expensive and I wish it came in smaller tubes. But this was the cheapest I found.

Dries water clear, holds well in solvent welded plastics, just be sure to thoroughly wet both surfaces. Gave 4 stars for value because soon after opening tube the remaining adhesive hardens in the tube and become useless. Not sure how long that really takes, but usually end up buying a new tube for every job.

i had a crack in one of the acrylic door trays on my 2 year old fridge. instead of paying the $60 to replace it (that's what samsung was going to charge!), i decided to try this and so glad i did! i actually ran a bead across the entire crack and just let it sit there on its own, and it worked its way into the crack and dried flat so you don't even see that it's there other than the matte finish. no need to work it into the crack, it was self leveling. bear in mind this was a crack, not a break.

I was slightly suspicious when I opened the tube and chemical immediately gushed out. Shouldn't there be a metal seal inside the tube? I called the manufacturer of Scigrip Acrylics 16 and they confirmed this. That's when I noticed the other label's directions showing through the Acrylics 16 label (which had been glued and taped over the original tube, wtf?)I could understand if that was the only issue, (if a manufacturer wants to reuse extra packaging from another product rather than waste the materials that's great) but in light of the other problems this stinks of piss poor QA and I'm not confident that I got the product I intended.

Didn't work for what I needed, haven't tried on anything else. So really have no comment.
