With 2025 Corporate Average Fuel Economy (CAFE) standards just 9 years away, automotive weight reduction is top priority as OEMs and suppliers work together to achieve 54.5 miles per gallon.
Chemistry is in the driver’s seat to help reach automotive lightweighting goals, enabling the development of more robust and sustainable automotive designs.
Henkel’s adhesives and functional coatings give designers the flexibility to introduce lightweight materials, while meeting competing demands for increased durability and performance and reduced noise and emissions.

With 2025 CAFE standards on the horizon mandating an average 54.5 mpg per vehicle, automakers and suppliers are examining every vehicle component and manufacturing process to subtract weight.
Liquid sealants make it possible to join dissimilar materials like metal and plastic, while reducing material costs 4 to 5 times compared to hard gaskets.
Zirconium oxide coatings enable an increased use of aluminum by improving corrosion prevention and decreasing sludge generation.
Structural adhesives can join dissimilar materials, while distributing stress more evenly across the joint — compared to fasteners and spot welding.
High-Damping Foam provides sound damping, while saving up to 2 kilograms of mass on doors and roofs.
Structural adhesives enable designers to specify thinner, lighter materials while meeting strength requirements.
Resin Transfer Molding for composites enables shorter injection times — increasing volume production from 20,0000 to 30,000 per year to 200,000 to 300,000 per year.
The average vehicle has approximately 27 pounds of adhesives versus 18 pounds just a decade ago.
