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 ordered this glue before and it worked great but this new bottle I just opened is like water. There is no adhesion at all, it's just like water and it's too late to return it. Considering the price went up since I last bought the first one it's lost money. I'm very unhappy that this happened. Cannot give this bottle a good review. If I could I would rate it lower than one star.

Item is good but did not get the needle. So little dissatisfied

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?

Luv the Product but order arrived incomplete said it had a Fine application bottle and syringe included just like the first time I ordered, called Amazon Customer Service and the said no return on said item and did not know why the Application Bottle was not in the box..... Still Waiting on response

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

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.
