Weld-On #40 Cement, Pint

Weld-On #40 is a medium bodied, hand mixed two-component (20:1 ratio), reactive, high strength acrylic based adhesive that provides "museum quality" water clear joints with excellent weatherability. Optional, use #3061 thinner for #40 (A). Refrigeration recommended.

• PROFESSIONAL-GRADE SOLVENT CEMENT — Weld-On #40 is a heavy-bodied, high-strength solvent cement formulated for bonding plastics in demanding fabrication and industrial applications. Its thick viscosity fills gaps and surface irregularities for a reliable, durable bond. Ideal where standard thin cements fall short, delivering consistent adhesion on properly prepared plastic surfaces.
• PINT SIZE READY TO USE — Supplied in a convenient pint (16 oz) container, this single unit of Weld-On #40 provides ample volume for professional fabrication, repair, and assembly projects. The heavy-bodied formula minimizes waste and allows controlled application. Always verify substrate compatibility prior to use for best bonding results.
• VERSATILE BONDING APPLICATIONS — Engineered for plastic bonding, fabrication, repair, and assembly across industries including signage, display, construction, and industrial manufacturing. Weld-On #40 is trusted by fabricators who need a gap-filling cement for joining plastic components where surface contact is less than perfect or parts require additional body support during cure.
• EASY FABRICATION APPLICATION — Apply Weld-On #40 using a brush or applicator to prepared plastic surfaces. The heavy-bodied consistency allows controlled placement and extended working time for alignment adjustments. Compatible with standard solvent cementing techniques used in plastic fabrication shops. Clean tools immediately after use with appropriate solvent per manufacturer guidelines.
• PRECISION TOLERANCES & QUALITY — Dimensions held to +/- 0.010" ensuring consistent, precise fit for fabrication and engineering applications. Manufactured under ISO 9001:2015 certified quality management standards for reliable material quality on every order.
