Sealing Technology Solutions

Structural bonding uses adhesives in load bearing applications to augment or replace traditional mechanical fasteners, including welding, screws, nuts and bolts, etc. Structural adhesives are used to reduce stress concentrations, improve service life, and provide excellent surface finish. These adhesives also offer benefits, such as improved product quality and production speed, as well as reduced costs to fabricators and builders. Advantages of structural adhesives include the ability to: 
  • Carry larger loads compared with mechanical fasteners (due to larger bond areas)
  • Fill large gaps
  • Dampen vibration
  • Reduce/eliminate corrosion between substrates
  • Lower manufacturing costs compared with mechanical fasteners
  • Lower labor costs compared to welding and threaded fasteners with faster cycle times and lower labor rates
H.B. Fuller offers a complete line of engineered structural adhesives. Our one- and two-part products offer a wide range of versatility in meeting your application requirements. Engineered to provide a unique balance of tensile, shear, and peel strength, they assure excellent performance in assemblies that see stress, shock, and impact. Strong, durable bonds are their trademark, even when faced with severe environmental conditions. H.B. Fuller's structural adhesives include epoxy, polyurethane (PU), methacrylate (MMA), acrylates, very high bond strength (VHB) acrylic tapes, and other resins.
