Weld-On #3 Cement, DCM & TCE Free Formula, Gallon and Weld-On Applicator Bottle with Needle (Pack of 2)

Weld-On #3 is a fast-setting, low-viscosity solvent cement formulated specifically for bonding acrylic (plexiglass) and other compatible thermoplastics. It works by chemically fusing surfaces together at a molecular level, creating bonds that are virtually invisible and nearly as strong as the base material itself. Buyers choose it for its clean, water-thin consistency that flows easily into joints by capillary action, producing crystal-clear, professional-grade results. high-performance of all, this formula is free of (DCM) and (TCE), making it a safer choice for enclosed workspaces without sacrificing bonding performance. Stocked and ships from West Nyack, NY. This adhesive is a go-to solution across a wide range of industries and applications, including signage fabrication, display case assembly, retail fixtures, aquariums, model making, architectural models, and point-of-purchase displays. Whether you're a professional fabricator joining precision-cut acrylic panels or a hobbyist building a custom enclosure, Weld-On #3 delivers consistent, reliable results. This pack of two includes applicator bottles and needles, giving you precise control over application and minimizing waste on every project. For high-performance results, ensure mating surfaces are clean, flat, and free of dust or oils before application. Apply the cement along the joint edge and allow capillary action to draw it into the seam, then hold firmly for 30 seconds and allow adequate cure time before handling. Avoid excess application to prevent crazing or cloudiness on visible surfaces. Plastic-Craft Products has been a trusted supplier of quality plastic materials since 1934.
