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

This works great for bonding acrylic and polycarbonate. I use it to make aquariums and aquarium accessories. The can I received was fresh stock.

hot cement, works great bonding Lexan to itself for seamless work.

Description says: “ Weld-On 4 Acrylic Adhesive - Pint and Weld-On Applicator Bottle with Needle” There is NO applicator or needle. Make sure you purchase separate bottles with needles before use. Fortunately I already had suitable bottles/applicators.

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

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.
