 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.

Weight saving:

Adhesives are particularly popular for light-weight constructions, where thin walled parts (wall thickness < 0.5 mm) must be joined.

Sealed joints:

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
