Weld-On 4 Acrylic Adhesive - Pint and Weld-On Applicator Bottle with Needle

I purchased this to “glue” plastic for 3d printing.I like it and it works like I thought it would. It a very thin liquid. I tried using a syringe but it still spills out with little control. But This is a me problem not a product problem.

If you use PLA for 3D printing like I do, you know that finding a glue that works with it is not easy. I have been using Plastruct Plastic Weld, but that has become hard to find recently, so I needed to find an alternative. For applications where I need a very thin glue that dissolves the surface of the plastic to "weld" the pieces together, this stuff works well. It can be used similarly to how acetone works with ABS. It evaporates quickly so you need to work fast. I used a syringe to fill the small applicator bottle, but don't put too much in the bottle because it will evaporate after a few days.

I was expecting what the description said. nope the can had a ding in it and the top was slightly open but was wrapped in plastic wrap..what a mess that was and no bottle/needle included

This stuff is awesome it drys clear, strong bond, works great

I like this glue, it is the right stuff for assembling acrylic projects. It is fully transparent and if applied correctly it makes a strong virtually invisible weld. However, it was disappointing looking for it on Amazon: there was only one option available, in this huge pint can, that wasn’t cheap and I had to pay for delivery and it is not free to return.It is basically a liquid, and you use very little of it, the rest is waste as it will dry up with time. So, unless you do a lot of glueing of plexiglass, look for some alternative source, but I do recommend this particular glue.

As a sign maker I've used methylene chloride to weld plastics for years. Nothing special about this product but what is special is the price is really good and the applicator is an appreciated add-on. The delivery was upgraded to "quick" and it was. I ordered on Friday and had the package on Monday.I used Weld-On today and it worked exactly as it was advertised and like I remember. Low price, quick delivery and a sheet that explains how to use the product; what more could I ask for?

This product produced a very strong bond on the display cases I made, but, it will run on areas and show if you are not careful. Practice on a sample before using it on something that matters.

Does not come with applicator needle
