On the road to sustainability with bio-based materials

Auto manufacturers and suppliers are working constantly to reduce energy consumption and CO2 emissions during vehicle production. A project team consisting of members from the carmaker Audi, BASF’s Coatings division and Covestro passed a new milestone: For the first time, a clearcoat containing a bio-based hardener was applied to test bodies of the Audi Q2 under realistic production conditions at the Audi plant in Ingolstadt, Germany.
The bio-based Desmodur® eco N 7300 helps reach sustainability targets without compromising product quality.

A central component of the clearcoat, tested on Audi’s Q2 model is Covestro’s renewable hardener Desmodur® eco N 7300. It consists of 70 percent biomass and provides the same, high performance as traditional materials. The clearcoat forms the top layer of the coating system, lending it scratch resistance, a glossy appearance and protection against sunlight and other weather effects.

“The use of bio-based raw materials in automotive coatings is still in its infancy,” says Thomas Heusser, head of Materials and Process Engineering at Audi. “But the application of the new clearcoat on our existing machines fulfilled all our specifications and delivered promising results. With this project, Audi takes up a pioneering role in this field in the automotive industry.”

This powerful industry cooperation stands as an example of high performance meeting sustainability and foreshadows a new era in automotive production.
