Structural Adhesives

Structural adhesive is used to bond materials together with as much strength as the surrounding structure. — The steel coupon warps & fails while the adhesive bond remains unaffected.

STRUCTURAL ADHESIVES WITH HIGH-STRENGTH BONDING FOR ENHANCED DURABILITY

Structural adhesives are critical for bonding materials with the strength and integrity needed to support load-bearing joints in various applications. Unlike traditional methods like welding and riveting, structural adhesive for metal and other materials provide a seamless, durable bond that maintains the structural integrity of the product. For example, the adhesive bond remains intact even when the surrounding materials fail, such as in the case of steel coupons that warp or fail under stress.

Superior Strength with Hernon’s Structural Adhesives

Hernon’s structural adhesives offer superior bonding strength and strong impact resistance, making them ideal for critical load-bearing joints. These adhesives are increasingly popular in industries seeking alternatives to traditional fastening methods like welding, rivets, and bolts. Structural bonding with Hernon’s products also offers several advantages, including reduced weight, lower costs, and faster assembly times compared to traditional methods. As highlighted in Assembly Magazine, Hernon’s structural adhesive solutions can even replace welding and rivets in many applications.

Advantages of Structural Adhesives:

Reduced cost per application compared to traditional fasteners
Water and chemical resistance for lasting performance
Diffuses stress across the entire bonded surface for enhanced durability
Fills imperfections and gaps while bonding, ensuring a perfect fit
Bonds dissimilar materials, providing versatility in applications
Seals and bonds at the same time, streamlining the process
Protects against galvanic corrosion, increasing longevity
Sand-able and paint-able when cured for a seamless finish
100% Active – No solvents, providing a cleaner and safer bond
Replaces heavy metal fasteners with lightweight polymers for more efficient designs
Easy application: Apply across the entire bonding surface in one motion
