IPS Weld-On 3 Acrylic Plastic Cement with Weld-On Applicator Bottle with Needle, 4 oz Can, Clear

awesome amazonian!

This product works well. It's extremely thin and evaporates quickly. It was difficult to unscrew the cap from the can but once this was done there is a snap-in insert in the opening that needs to be pried open. When I did this for the first time, the insert went airborne. I used the product and it worked. When I went to use it a second time, the insert popped again but not as high. Just be aware of this when you use it.It also dissipates very quickly. You must be fast when using the product. I used a brush to apply it to the acrylic that I was gluing. It evaporates instantly so I had to re-load the brush multiple times to get enough of the product onto my project. FYI.

Be warned, this stuff is very thin. Need to have a good way to apply or risk ruining your 3d prints.With that said, I have not had a lot of experience gluing prints together as of yet. But the limited times I've used it, this stuff sticks it together!Really wish they would produce a 3d glue specifically for 3d printing.

I bought this repair a broken acrylic drawer in my freezer and it worked great . This is not a glue. It actually melts acrylic together.. the joint it creates can be stronger than the original material. It also works perfect on polycarbonate materials.. I have built many explosion proof boxes out of polycarb thick sheets for Boeing using this Weldon product.

Does not weld acrylic as advertised and applicator does not work properly. The “glue” spills all over as soon as you lean the applicator, no pressure need to expel it from the applicator. Evaporates very quickly.

Solvent works fine but the applicator bottle is a joke, it leaked everywhere out of the cap and then stopped working after the first weld. I happened to have some disposable needles for applying paint in small areas of 3d prints so I just tried those and they worked fine, not the cleanest looking weld but I don't care what it looks like. They should just stop selling this with an applicator bottle so no one is taken by surprise when they receive this unusable garbage.

I have friends that recommend Weld-On 4 because it runs less, but I like how Weld-On 3 just instantly fills all those tiny gaps. This stuff really does a great job.There have been some reviews about not being able to open the can. I too had the same problem when it arrived, but then I had a long think about it and realized that the lid may be crimped down. I looked at the can and sure enough, it had a lip just like a paint can. I whipped out my paint-can opener and it did the job. After prying up just a tiny bit as I worked around the lip of the can, I was able to simply twist off the lid.I read some more reviews that said that the product just evaporated because the can could not be sealed well. What I did was, after getting the cap off, make the tiniest of tiny holes in the lid (which has embossed lettering "cut away to open" or something like that -- I ignored that message and just used a knife to make a tiny hole) big enough to fit the hypodermic end of the bottle into the can.I just squeezed out some air, shoved the needle in the hole, tilted the can, waited 20 seconds, and I had enough liquid in the bottle to do my glue-up.Once done, the inside of the screw-cap has a seal on it that once screwed-down should prevent any vapor from escaping. However, to further prevent loss of product, I then stuck the whole thing back in the plastic baggy that it came in. Will update if the product has all evaporated in a couple weeks, but I do think that it will not evaporate as I was careful to put only a small hole and also to *properly* remove the screw cap without damaging its seal or sealing capabilities.

This is a very effective solvent adhesive for Plexiglas and the like. Be aware that it takes skill to use it without getting it all over the place as it is very liquid. Drying time is minimal and you can hand hold it while it cures enough to set.
