## Overview

Weld-On 4 Acrylic Adhesive is a moderately fast-setting, water-thin solvent cement designed for high-strength, blush-resistant bonding of acrylic and other thermoplastics. Delivered in a convenient pint bottle with a precision needle applicator, it forms strong bonds with a tensile strength of 2000 PSI, ideal for professional applications like sign fabrication, medical equipment, and display cases.

## Description

Moderately Fast-Setting Solvent Cement for Bonding Acrylic. WELD-ON 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. WELD-ON 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, WELD-ON 3 is recommended. Weld-On 4 Acrylic Adhesive water thin, somewhat flammable, moderately fast-setting, blush-resistant solvent cement for bonding acrylic. It will also bond with other thermoplastics such as polystyrene, CAB (cellulose acetate butyrate), and polycarbonate to themselves. Does not bond to cross-linked acrylics. SUBSTRATE RECOMMENDATIONS : WELD-ON 4 is formulated as a blush-resistant cement for bonding acrylic (poly-methyl methacrylate) to itself. It will also form strong bonds with other thermoplastics such as polystyrene, CAB (cellulose acetate butyrate), and polycarbonate to themselves. It is not recommended for cross-linked acrylic. SUGGESTED BONDING APPLICATIONS: WELD-ON 4 is used extensively in sign fabrication for cementing acrylic letters to fat acrylic presentation panels and trim-capping of cut out acrylic letters. Strong butt joints are made with fat sheets by using the soak method. WELD-ON 4 is also widely used in many applications e.g. fabrication of display and presentation cases, medical equipment assembly, the bonding of plastic containers and pre-forms, and in the manufacture of numerous solvent welded structures and subassemblies using the capillary method.

## 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
