In the automotive industry, manufacturers and suppliers are working constantly to reduce energy consumption and CO2 emissions in production. The cooperation intended to show that sustainable car coatings are a promising field that can contribute to this endeavor in the future.
On the road to sustainability
A project team consisting of members of the car maker Audi, BASF’s Coatings Division and materials company Covestro aimed to pass a new milestone: for the first time, a clearcoat containing a biobased hardener was applied to test bodies of the Audi Q2 under near-series conditions at the Audi plant in Ingolstadt, Germany.
BASF developed the clearcoat using the biobased hardener Desmodur® eco N 7300 from Covestro. A total of 70 percent of the hardener’s carbon content is sourced from renewable raw materials. This innovation reduces the consumption of fossil resources. 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.
After the successful coating of test bodies of the Audi Q2, Thomas Heusser, Head of Materials and Process Engineering at Audi, is optimistic: “Even though not all tests required for approval of the coating for use in full-scale production have been concluded, the three companies have taken an important step toward an even more sustainable automotive coating process.”
The Audi Q2, displayed at the European Coatings Show 2017, stands as an example for high performance meeting sustainability and foreshadows a new era in automotive production.
