Sika is your Strategic Partner for Process Improvements in the Weld-Shop

Sika's structural bonding solutions for metal-to-metal bonding consist of a variety of technologies. SikaPower® epoxy adhesives allow commercial vehicle manufacturers to replace welding with bonded joints. It is becoming increasingly difficult to hire personnel for welding work. The partial replacement of welds by thermosetting or room-temperature-curing epoxies helps our customers with automation and cost-optimization projects. Aluminium can be easily joined to steel using Sika's bonding solutions. The welding of panels to substructures in bus production brings a significant need for treatment to achieve a flat surface finish.
