No Slide Metal/Composite Bonder. Revolutionary Metal Bonder will hold heavy parts at application without sliding either on a vertical or overhead surface. AT-8040 will hold 3,500lbs in 40 minutes. No Welding, Drilling or Tapping. Weld Mount AT-8040 is a solvent free, VOC Compliant, two part methacrylate-based, structural adhesive formulated to bond metals for use in severe environments. It will also bond engineered thermo- and thermosetting plastics, composites to metals or various substrate combinations. It has excellent adhesion to as received metal surfaces including aluminum, stainless steel, galvanized steel, and plated steels. AT-8040 forms a tough, high strength bonds usually with minimal surface preparation developing handling strength in 12 minutes and a functional cure within 45 minutes. Ultimate strength exceeds 3500 psi of tensile shear strength on aluminum with remarkable impact and peel strengths. AT-8040 will hold all Weld Mount parts on a vertical or overhead surface w Revolutionary Metal Bonder will hold heavy parts at application without sliding either on a vertical Features . Revolutionary Adhesive Parts Stay Where Placed Without Sliding. For Use Overhead and on Vertical Surfaces No Need for Fixtures
