## Description

This product is for INDUSTRIAL USE ONLY and not for use at homes, schools or in recreation. This is an industrial product intended for use by industry. Plastic-Craft Products reserves the right to substitute similar quantity of Weld-On 4SC for Weld-On 3 or Weld-On 4 when ordered by an individual consumer. This product must ship via ground transport. This product may not be shipped into Los Angeles, San Bernardino, Orange, or Riverside Counties. Plastic-Craft Products reserves the right to substitute Weld-On 4SC for Weld-On 3 or Weld-On 4 when ordered for delivery to zip codes in those counties. SCIGRIP 4 is a water-thin, somewhat flammable cement formulated to quickly develop very clear and high strength bonds for many thermoplastic substrates. The bond is achieved by first softening the surfaces to be joined and then fusing them together with the dissipation of the solvent. The initial bond forms within a matter of minutes and is followed by a significant and continual increase in bond strength over the next several hours. SCIGRIP 4 may be preferred by some plastic fabricators because it is less likely to leave white marks (commonly called blushing). For similar applications but faster setting cement, SCIGRIP 3 is recommended. This product is not for general consumer use. It is an industrial product intended for use by industry.

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
Review: Very good product. - 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!

## 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

### ⭐⭐⭐⭐⭐ Best Ever 3D printer project Glue!
*by A***R on February 9, 2026*

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.
