Most commonly used within automotive, aerospace, electronics, construction, engineered wood, medical, and consumer industries, structural adhesives are well suited to an extremely broad range of applications. They are used for applications concerning magnet bonding, metal bonding, multiple surface bonding, NVH – noise, vibration, and harshness reduction, plastic and composite bonding, and potting and encapsulating, among many other applications.
Structural Adhesives
Two-Part Structural Adhesive
- Elimination or significant reduction of costly mechanical fastening methods
- Improved aesthetics compared to mechanical fasteners
- Uniform weight distribution over the substrate
- Multi-substrate bonding: Joining of different (dissimilar) substrate materials
- Fast processing speeds
- Ideally suited for low weight or weight reduction applications
- Reduction in labor costs
- Filling of large gaps between parts
- User-friendly packaging and applicators
Structural Adhesives for Metal and Plastic Bonding
High-strength, lightweight structural adhesive metal bonding formulas make all the difference in applications where metal substrates and components must be assembled. Epoxy structural adhesives are very often used with applications where metal bonding is required, although anaerobic and acrylic adhesives may also be used. Improving process efficiency in both new and established designs remains a challenge for manufacturers, and Henkel’s range of structural adhesive metal bonding products promote efficiency and cost-savings without compromising on strength, impact resistance, or aesthetics.
Acrylic and polyurethane adhesives are also commonly used for plastic and multi-substrate bonding. This makes them particularly well-suited for a wide variety of different plastic substrate bonding where high-strength hold is required in addition to resistance from humidity and environmental factors.
Structural Adhesive Aluminum
Aluminum provides its own set of challenges, and proper preparation to remove oxide build-up before application is key. Anaerobic, cyanoacrylate, and epoxies are most commonly used as aluminum structural adhesives, ensuring strong bonds and impact resistance for a range of aluminum alloys. Pushing for more efficient processing and cost-savings in all types of design, Henkel’s range of products is ready to meet your specific requirements.

Two-Part Structural Adhesive
Many types of structural adhesive offer 2-part application and a broad range of cure speeds. Suitable for bonding all types of substrates, these versatile and flexible solutions allow for greater control during the application process. In essence, 2-part structural adhesives allow for room temperature curing either manually or through the use of applicator nozzles in automated processes. This means safer and more efficient bonding while improving accuracy and aesthetics both during and after application.
Structural Adhesive Sealants
Structural sealants prevent the loss of pressure or liquids as well as protecting components against condensation and corrosion. Ideal for filling spaces between parts or sealing pipes, while also providing excellent adhesion on a variety of substrates, structural adhesive sealants bridge the gap between conventional sealants and adhesives. Application can be made either manually or automatically, and a range of formulations allow for flexibility across a wide range of industrial and commercial design, including high-performance gasketing and flange sealing.
