The Weld Mount AT-8040 is a revolutionary metal bonding adhesive that holds heavy parts in place without sliding on vertical or overhead surfaces during application. This high-strength structural adhesive achieves 3,500 psi tensile shear strength in just 40 minutes—eliminating the need for welding, drilling, or tapping.
This solvent-free, VOC-compliant, two-part methacrylate-based adhesive is specifically formulated to bond metals in severe marine, automotive, and industrial environments. AT-8040 provides excellent adhesion to as-received metal surfaces including aluminum, stainless steel, galvanized steel, and plated steel, usually requiring minimal surface preparation. It also bonds engineered thermoplastic and thermosetting plastics, composites, and various substrate combinations.
The adhesive develops handling strength in just 12 minutes and reaches functional cure within 45 minutes, with ultimate strength exceeding 3,500 psi. It features remarkable impact and peel strength, making it ideal for demanding applications. When properly used, AT-8040 will securely hold all Weld Mount parts on vertical or overhead surfaces without sagging.
