Sika is at the cutting edge of technology for lightweight vehicle manufacturing

There are currently some one billion registered passenger vehicles, and the number grows every year. Due to the challenges posed by resource scarcity, rising energy consumption, and increasing co2 emissions, more efficient vehicles will undoubtedly be needed in the future. In this respect, there is one crucial factor. While a few grams of co2, or a little material or energy saved by shaving a few kilograms off one vehicle’s weight may seem modest, the results are significant over the millions of new cars that are manufactured every year. Even small improvements can add up quickly.

Traditional material fastening methods, such as rivets, screws, and welding techniques like spot welding, are being replaced or supplemented by adhesive bonding methods that are not just ultra-high strength, but also remain elastic. These adhesives must not only adhere equally well to different materials, but also compensate for their different expansion characteristics, while also maintaining just the right amount of stiffness and providing optimum handling.  

Sika’s adhesive technologies and products point the way toward high-performance lightweight construction and represent a substantial contribution to sustainable mobility.


Ultra-high modulus (UHM) Sikaflex® adhesives are a new development that demonstrates Sika’s early response to the increasingly wide range of materials being used in automotive design. They enable quick bonding processes with multi-material combinations, while guaranteeing durable functionality. Sikaflex® UHM adhesives are unique within the industry; they are suitable for both fully automated adhesive application on the assembly line, as well as manual application. The pioneering all-electric BMW i3 is the showcase for the new Sikaflex® UHM adhesive technology.
