Weld Mount No Slide Metal/Composite Bonder [8040]

Weld Mount AT-8040 is a two-part methacrylate structural adhesive for bonding metals, engineered thermoplastics, thermosetting plastics, and composites to metals or other substrate combinations. Its no-slide formulation holds Weld Mount parts in place on vertical and overhead surfaces without sagging when properly used, reducing the need for fixtures, welding, drilling, or tapping.

Bonding and application

• Formulated for metal bonding in severe environments.
• Adheres to as-received aluminum, stainless steel, galvanized steel, and plated steels, usually with minimal surface preparation.
• Forms tough, high-strength bonds with impact and peel resistance.
• Solvent-free formulation described in the supplied product information as VOC compliant.
• Designed to keep parts where placed during application, including on vertical and overhead surfaces, without fixtures.

Cure and strength information

• Listed handling strength: 12 minutes.
• Listed functional cure: Within 45 minutes.
• Listed ultimate tensile shear strength on aluminum: Greater than 3,500 psi.
• The supplied copy also states “will hold 3,500 lbs in 40 minutes,” but does not specify the bond area, substrate, or test conditions for that claim. Do not treat it as a rated working load; confirm application requirements and cure conditions in the manufacturer documentation.
