Covestro (Leverkusen, Germany) is a longtime supporter of initiatives by students at Germany’s RWTH Aachen University and FH Aachen to make mobility more sustainable. The latest chapter in that partnership is the development of an electric car powered by solar energy that will compete in the Bridgestone World Solar Challenge 2019.
Coming off a third place win in the European Solar Challenge 2018, the Sonnenwagen Team of students is aiming for the stars, er, sun, in this upcoming challenge, which is said to be the toughest solar car race in the world.
Covestro is supporting the project with a variety of materials and technical services as well as through its sponsorship, said Julia Karmer, who heads the project within Covestro. The primary objective, she added, is to test new materials under extreme climatic conditions.
The Sonnenwagen incorporates polyurethane and polycarbonate materials from Covestro and a three-layer polyurethane coating from automotive coatings supplier PPG. The top clear coat is formulated with bio-based hardener Desmodur eco N 7300 from Covestro, which comprises 70% carbon content sourced from biomass.
The Covestro Sonnenwagen will make its first public appearance in Aachen, Germany, on July 22.
Covestro will exhibit at K 2019 in booth A 75-1 to A 75-3 in hall 6.
