Structural Adhesives

In a shear strength test, steep coupons are pulled past each other. The structural adhesives in the center holds strong while the steel strip warps and then breaks under the pressure.

Hernon Manufacturing structural adhesives with superior strength are more resilient than steel in this shear strength test. The steel coupon warps & fails while the adhesive bond remains unaffected.

Structural Adhesives with Superior Bonding Strength

Structural adhesives include any type of adhesive used to bond a load-bearing joint. These joints are necessary for the structural integrity of a product and are the most important bonds in a product. Failure of a structural bond is catastrophic to the product’s structure and function. As adhesive material technologies advance new techniques and formulas are available to secure structural bonds. Manufacturers are increasingly interested in when and how to use adhesives in structural bonding and what advantages are offered over welding, rivets, and other fasteners.

As a world leader in structural adhesive development, Hernon structural adhesives feature high bonding strength and uniquely strong impact resistance. They also offer advantages such as lower weight and cost reductions when compared to traditional fastening methods. Hernon’s adhesives can even replace welding and rivets in this article in Assembly Magazine called “How To Use Structural Adhesives to Replace Welding and Mechanical Fasteners.”

“A huge advantage to advanced product design is that structural adhesives can be pre-applied to parts otherwise inaccessible to mechanical fastening or welding during the assembly process. This revelation enables engineers not to be bound in their innovation of design by previous obstacles of space and accessibility. An additional benefit is a reduction in the amount of time it takes to join substrates. Welding or installing mechanical fasteners generally is much more time consuming compared to using an adhesive.”
