Freedom of Design

Sika's bonding solutions allow joining dissimilar substrates without restrictions. Eliminating the limitations of mechanical fasteners or welding is one of the key reasons why many adhesives are used in industrial manufacturing.

Process Optimization

Sikaflex® silane-terminated polymers (STP) allow the reduction of surface preparation steps. Fast cure Sikaflex® adhesives with SikaBooster® enable shorter handling time and more production output.

Durability of Vehicle

Fully bonded structures with Sikaflex® adhesives reduce stresses in the design. Compared with screws, they avoid damage to the corrosion protection coating and lead to increased durability. Connections with SikaPower® SmartCore adhesives can be more  durable than welded joints or mechanical fasteners thanks to its unique fatigue performance.

Vehicle Weight Reduction

Modern vehicle design integrates different materials and lightweight composites with Sika's adhesive technologies. SikaPower® SmartCore adhesives allow lighter vehicles by reducing metal thickness while still meeting strength and durability requirements.

Sika Panel Bonding Product Lines for Industrial Assembly Processes

Sika’s body panel adhesives for use in the production of commercial vehicles allow fully bonded load-bearing structures. Such a design avoids damaging the corrosion protection layer, e.g., by drilling holes or mechanical fixtures. It enables the integration of lightweight composite components and enables assembly of parts at any stage of the process.
