Weld-On #3 Cement, DCM & TCE Free Formula, Gallon, with Applicator Bottle & Needle

**Q: Is this adhesive safe to use indoors?** A: Weld-On #3 is DCM and TCE free, making it a safer alternative to older solvent-based adhesives. Always work in a well-ventilated area and follow all safety guidelines on the product label. **Q: What materials does Weld-On #3 bond?** A: Weld-On #3 is formulated primarily for bonding acrylic (Plexiglas) to acrylic, delivering clean, strong, nearly invisible bonds ideal for clear plastic fabrication. **Q: What is included with this listing?** A: This listing includes one gallon of Weld-On #3 adhesive along with an applicator bottle and needle for precise, controlled application. Weld-On #3 is a fast-setting, water-thin solvent cement designed specifically for bonding acrylic plastics. Its DCM and TCE free formula reflects a commitment to safer working environments without sacrificing bond quality. Fabricators choose this adhesive for its ability to produce crystal-clear joints that virtually disappear into the finished piece — a must-have for professional-grade acrylic work. This adhesive is widely used across sign making, display fabrication, retail fixtures, aquariums, architectural models, and custom acrylic enclosures. The included applicator bottle and needle allow for capillary application along seams, giving fabricators clean, precise control.

• Gallon Size Supply — Packaged in a full 1-gallon container, this bulk quantity cement is suitable for high-volume fabrication shops and production environments requiring consistent adhesive availability. Designed for efficient dispensing and repeated use across ongoing plastic assembly and repair workflows.
