Structural adhesives have become increasingly popular for various applications due to their strength and versatility.
FREMONT, CA: A strong, cost-effective, and fast-joining technology, structural adhesives have become increasingly important to industrial manufacturing in recent years. Technical developments in adhesive bonding technology have benefited the automotive, airplane, shipbuilding, electronics, and construction industries. Components and bonding processes have become more complex as lightweight and multi-material designs, progressive integration and miniaturization, and increasing complexity have emerged.
Many bonding and manufacturing processes across multiple markets have embraced structural bonding, despite some challenges, such as lower thermal resistance and instant strength.

Structural adhesives have high strength: They offer a high level of strength, one of their main advantages. The bond strength of some structural adhesives is so high that they provide a very reliable connection between materials comparable to welding. A structural adhesive's bond strength is measured in pounds per square inch (PSI). MegaPascal (MPa) is the unit of measurement we use at Forgeway when assessing adhesive strength, and 1 MPa is the same as 145 psi. A structural adhesive's strength is determined by its type. In terms of strength, epoxy adhesives are the strongest. The strength of some epoxy adhesives can exceed 60 MPa/9000 psi (the same as a weld).
Structural adhesives can withstand movements and vibration: Structural adhesives can also be very durable and withstand vibrations and movements due to the formulations developed by some adhesive manufacturers. The added flexibility may reduce strength, but it prevents bond failure from being caused by vibrations or impacts. Adhesives should be flexible as well as strong. As a result, structural adhesives can be applied to many different applications due to their ability to withstand vibrations and movement.
Structural bonding: Positive-locking joining processes such as material-locking, force-fitting, and structural bonding offer practical advantages. By using it, dissimilar materials, including metals, polymers, glass, ceramics, or low thickness, can be combined previously impossible (or only possible at a significant disadvantage) with other joining processes. Adhesive bonding also offers homogenous stress distribution through two-dimensional force transmission, the ability to compensate component tolerances, and the ability to add a seal and corrosion protection function in addition to vibration dampening. It is now commonplace for many bonding and manufacturing processes across multiple markets to use structural bonding, despite some challenges, such as lower thermal resistance and the issue of debonding.
