Henkel's latest structural adhesive innovations have been specially formulated to provide tough, durable bonds to a wide variety of surfaces.
Structural adhesive products fall under the LOCTITE® and TEROSON® brands. Structural adhesives are engineered to meet a wide range of industrial bonding, sealing and assembly requirements.
LOCTITE® structural adhesives are available in easy-to-use packages for hand-held, manual and semi-automated applications, including cartridges, syringes, soft-squeeze bottles and dual cartridges for two-part formulations.
LOCTITE structural adhesives are also offered in larger packages such as 5- or 55-gallon pails for high volume dispensing and automated assembly operations.

Advantages of Structural Bonding and Sealing Methods
More uniform stress distribution over the entire bond face:
This has a very positive effect on the static and dynamic strength achieved. Where welding and riveting result in localized stress peaks, adhesive bonding achieves uniform distribution and absorption of stress loads.
No change in surface and texture of the joined materials:
Welding temperatures may change the texture and, therefore, the mechanical properties of materials. In addition, welding, riveting and fastening all affect the visual appearance of the parts.
Adhesives are particularly popular for light-weight constructions, where thin walled parts (wall thickness < 0.5 mm) must be joined.
Adhesives also act as sealants, preventing loss of pressure or liquids, blocking the penetration of condensation water and protecting against corrosion. Our liquid sealants offer flexibility and fit the requirements of most applications.
Joining dissimilar materials and reducing the risk of corrosion:
The adhesive forms an insulating film to prevent contact corrosion when different types of metals are joined. It also acts as electrical and thermal insulator.
Structural Adhesive Benefits:
- Elimination or significant reduction of costly mechanical fastening methods
- Improved aesthetics compared to mechanical fasteners
- Fast processing speeds
- Reduction in labor costs
- Filling of large gaps between parts
- User-friendly packaging
