First automotive refinish coating with bio-based hardener

Fri, 22 Sep 2017 00:00:00 +0200

Electric mobility and photovoltaics play a vital role in protecting the climate and conserving fossil resources. Combining them leads to even more innovative and sustainable mobility concepts. To show that these kinds of solutions are already feasible using state-of-the-art materials and technologies, a team of around 45 young researchers has developed a solar-powered electric car. Calling themselves “Team Sonnenwagen,” the students from RWTH Aachen University and Aachen University of Applied Sciences intend to enter their vehicle in the Bridgestone World Solar Challenge 2017 in Australia, probably the toughest race in the world for solar cars.

��AV is supporting the Sonnenwagen project with materials and technical service and as a gold sponsor. The company wants to use the project to test coatings under the harsh climate conditions prevailing along the race’s route. Temperatures in the Australian desert can soar to as much as 45 degrees Celsius in October, with intense UV radiation. This time of year also typically sees a high particle concentration in the air.

Road test: automotive coating with sustainable raw material
The most important product application is a three-layer polyurethane coating from PPG, world leaders in paints, coatings and specialty materials, and experts in automotive coatings. The coating system is particularly suited to coating body parts made of carbon fiber composites. Climate conditions have a significant impact on the top clearcoat. The Sonnenwagen uses an innovative automotive refinish coating that contains ��AV’s bio-based hardener Desmodur® eco N 7300. “Some 70 percent of its carbon content comes from biomass,” explains Ulf Wentzien, global head of Industrial Marketing in the Coatings, Adhesives, Specialties Business Unit at ��AV. “This reduces the environmental footprint by around 30 percent.”

“The bio-based hardener achieved the highest sustainability standards and meets both our customers’ and our own requirements,” says Ignasi Roig, EMEA Product Platform Manager at PPG Refinish. “The coating is to the same outstanding quality as a polyurethane clearcoat with a conventionally produced hardener.”

Easy processing
The two-component coating is also impressive on the practical side. In PPG’s training center in Hilden, it was applied to the Sonnenwagen's bodywork parts under similar conditions to an automotive paint shop. The application can be viewed in a video, see . The coating is particularly suitable for the temperature-sensitive surface of the solar-powered car as it hardens at low temperatures.

��AV and PPG have been working together in the field of coatings development for many years now. Both partners are using the Sonnenwagen project to demonstrate the role coatings can play in sustainable mobility.

Tough test for solar cars
The World Solar Challenge is considered to be the toughest race on Earth for solar cars and this year celebrates its 30th anniversary. From October 8 to 15, 2017, approx. 40 teams from all over the world will be competing in their “homemade” vehicles to win the 3,000 kilometer race from Darwin to Adelaide – without using one drop of fuel. The Sonnenwagen from Aachen will be the only German car going to the starting line in the Challenger Class this year.

��AV has a long-standing partnership with the RWTH Aachen University. “Through our developments and this project partnership, we are committed to future mobility and aim to show that these kinds of concepts are already feasible,” says ��AV’s Ulf Wentzien. “At the same time, we have the opportunity to inspire and support young people at universities.”

Innovative materials for electric mobility

Mon, 12 Jun 2017 00:00:00 +0200

How can we make the mobility of the future as sustainable as possible? A group of highly motivated students at RWTH Aachen University and Aachen University of Applied Sciences posed this question and, to find out, dedicated their efforts to an ambitious project: the development of a solar-powered electric car for what is likely to be the toughest solar car race in the world, the World Solar Challenge 2017 from October 8 to 15 in Australia. To make their idea a reality, the approximately 45 junior researchers established the “Sonnenwagen Aachen e.V.” association, with the support of their professors.

��AV, a leading global supplier of innovative and sustainable material solutions, shares the students’ enthusiasm and wants to join forces with them to push existing boundaries and make the project a success. The company has cultivated a long-term partnership with the distinguished university and is supporting the “Sonnenwagen” (German for “solar car”) project as both a material and technical service provider and Gold Sponsor. The two partners recently signed a cooperation agreement for the project.

Partnership for solar mobility
“As sustainability is part of our strategy, we support this ambitious project, in which young researchers want to show that innovative and sustainable mobility concepts are already possible today,” says Dr. Markus Steilemann, Board Member for Innovation and Chief Commercial Officer of ��AV. “Solar mobility can make a key contribution to protecting the climate and conserving fossil resources. With our developments and this project partnership, we want to demonstrate our commitment to innovation and sustainability, but also to supporting junior talents.”

Hendrik Löbberding, First Chairman of Team Sonnenwagen, welcomes the new partner: “We are very grateful for ��AV’s support and will benefit above all from its superior competence in materials.” The Leverkusen-based company already has gained extensive experience using its innovative materials for solar mobility: As an official partner of the Solar Impulse project, it made a significant contribution to the success of the first manned flight around the globe in an aircraft powered exclusively by solar energy.

Road test: automotive coating with bio-based hardener
��AV wants to take advantage of the Sonnenwagen project to test various materials under the harsh climate conditions prevailing along the race’s route: temperatures of up to 45 degrees Celsius, high UV radiation and a high air dust content are typical there in October. The most important product application is a three-layer polyurethane coating from PPG, a leading global manufacturer of automotive coatings. The coating is particularly suited to application on body parts made of carbon fiber composites.

The climate conditions have a significant impact on the top clearcoat. It is formulated with the bio-based hardener Desmodur^® eco N 7300 from ��AV, 70 percent of whose carbon content is sourced from biomass.

The Sonnenwagen further incorporates polyurethane and polycarbonate materials from ��AV, which contribute to the lightweight and aerodynamic design of the solar car.

Acid test for solar cars
The World Solar Challenge is considered to be the toughest solar race on earth and celebrates its 30th anniversary this year. Teams from all over the world compete every two years in their homemade vehicles to win the 3,000 kilometer race from Darwin to Adelaide – without using one drop of fuel.

The Sonnenwagen from Aachen will be the only German car going to the starting line in the Challenger Class this year. The team is very optimistic about its chances in the race: “We already have experience with zero-emission mobility and feel well-equipped to take part in the competition with the roughly 40 other teams from five continents,” says Hendrik Löbberding of Sonnenwagen Aachen team.

Two members of the association raced an electric car in, and won, the e-CROSS Germany, a four-day, climate-neutral rally through North Rhine-Westphalia. One month prior, the Sonnenwagen members accompanied a team from Bochum in the European Solar Challenge 2016, a 24-hour race in solar cars.
