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

COMMON QUESTIONS: SCIGRIP Weld-On #3 is a water-thin, solvent-based acrylic adhesive that works by capillary action — flowing into the joint and chemically fusing two acrylic surfaces into a near-invisible, permanent bond. At 8000 PSI tensile strength and rated from -40°F to 180°F, it delivers professional results whether you're bonding a retail display case or a precision fabricated sign. This DCM and TCE free formula meets ASTM D4802 and is safe for shop and studio use. Stocked and ships from West Nyack, NY. Fabricators, sign makers, display builders, and laser cutting shops rely on Weld-On #3 for its optical clarity and fast cure. Each pack includes three 4 oz bottles plus applicator bottles and needles — giving you precise control exactly where the adhesive needs to go. Compatible with laser-cut and CNC-machined edges, it bonds cleanly without fogging or residue, making it ideal for any application where appearance matters.
