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 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.

The cement is amazing, but the tips were not included.

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.

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.

Used this to join 3D printed PETG parts, dries fast and strong. Wear PPE while using!

The reason I purchased this product was for the micro tips but they performed poorly. They are attached by a pressure fit and no matter how I attached them, they would fall off while applying, dripping cement and causing damage to the item I was gluing. One of the new tips was already clogged before I used it. The cement did a poor job of creating a strong enough bond keeping a cracked plastic drawer together but it could have been a result of not being able to accurately place the cement on the edges due to the micro tips. Do not waste your money on this product if you are looking for a cement that can be precisely applied. I would choose a liquid with a syringe applicator if I had to do it over again.

Very running and creates a glue mess if the tube is not held in an upright position. This also leaves 'bubbles' in the finished job. This does do a good job (so far) at 'welding' acrylic pieces to each other.
