Review: Best Ever 3D printer project Glue! - This is the best glue I have tried for some of the 3D printer projects I have made. It is forgiving just a little when putting the smaller parts together (a little wiggle room before setting up). It dries quickly too. It came with a little squeeze bottle that makes applying the glue very easy and not messy. Because it is a pint can, it will be quite a while before running out, making it a very good deal.
Review: Great adhesion invisible if you apply it right - I have been using adhesive sheets to assemble my acrylic creations but needed something that would ensure a permanent bond in hot humid situations. I apply using a syringe and love the way it seems to be sucked in-between the layers and creates a bond within minutes. Sometimes just long enough to maneuver the pieces of I realize they aren't quite positioned right. A great alternative to adhesive sheets in some situations just be careful not to get it onto the finished surface

## Questions & Answers

**Q: I am wanting to bond .25 inch sheets together to make one inch sheet of plexiglass. Is this what I need.**
A: This product works quite well to plastic weld acrylic (plexiglass) together.
Are you hoping to bond the .25" sheets together in order to make a thicker overall sheet? If so, I believe the final product could come out cloudy. This is due to my experience of using too much adhesive it running onto the face of the plastic I am bonding.

**Q: Is this a methacrylate adhesive ?**
A: Weld-on #4 is designed specifically for thermoplastics (one being poly-methyl methacrylate). I would advise reading over the data sheet before purchasing. - Acrylic Habitats         https://www.gogsg.com/ASSETS/DOCUMENTS/ITEMS/EN/ips4-04_spec.pdf

**Q: Will this work bonding Polycarbonate to Acrylic?**
A: Probably, but I;m not sure. If you have any of the produce, try on a sample.

**Q: Will this bond Corian sheets face to face?**
A: I don't think so, weld on 16 maybe but there has to be better adhesive for the job

### ⭐⭐⭐⭐⭐ Very good product.
*by A***R on February 1, 2026*

I’m new at repairing acrylics so got the slower setting one. It still sets pretty quickly, but gives you some time to adjust placements. Great hold. Bottle also comes very well sealed, I almost gave up opening it until I finally got it open. Only issue is this size was much larger than I need!
