Have a design challenge?
Sika can support in the conception phase, as well as providing customised solutions to optimise production lines.
Increase production output and save time
Fast setting and accelerated adhesives reduce handling time and reach full cure quickly. Used in combination with all in one sealing and bonding solutions, or adhesives that require no or little surface preparation can increase production output.
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.
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 Adhesives Lines for Industrial Assembly Processes
Sika’s adhesive sealants and structural panel bonding 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 the assembly of parts at any stage.
General Mixed Material Assembly
Elastic bonding enables the combination of different materials. Typical challenges in mixed material designs are related to different thermal elongation of the bond materials, surface preparation, and process parameters.

For the structural integration of lightweight components such as Thermoplastics and Thermosets, structural adhesives with high elasticity are ideal for coping with challenges in mixed material designs:
Elastic adhesives like 1C Sikaflex® panel bonding adhesives can be accelerated with Sika®Booster and are very versatile and easy to use option:
In industrial assembly, 2C SikaForce® structural urethane adhesives combine high shear strength with specific process benefits like primerless adhesion, and unique snap cure effect.
Large Component Assembly
When joining large components in industrial assembly, the application of the panel adhesive and the assembly process require significant working time. On the other hand, curing speed is essential to move the assembly to the next steps. Sikaflex® Booster technology and SikaForce® Curing by Design products combine these aspects perfectly:
Structural adhesives like SikaFast® acrylic adhesive systems are ideal for replacing mechanical fixtures such as rivets, screws, or welded joints. SikaFast® acrylic adhesives combine high shear strength and fast strength development with minimal surface preparation for a wide range of bonding surfaces.
Composite Shell to Shell or Shell to Frame Assembly
Many thermoset composite vehicle parts consist of different components that are bonded together. Often this is required to reinforce vehicle parts. Sika’s structural polyurethane adhesives integrate well with your process requirements. From automation to high cure speed while maintaining enough handling time, SikaForce® structural adhesives help you increase your production output.
Weld Shop Assembly and Metal Bonding
Adhesive bonding has proven to improve the effectiveness and efficiency of assemblies in the weld shop or body shop. Using structural adhesives to bond stiffeners and panels reduces the dependency of scarce welders and enables faster processing with fewer posttreatment steps. Sika’s experts guide you in implementing adhesive bonding into your weld shop.
