AkzoNobel coatings make Nuna7 a hot prospect

July 2, 2013 - Amsterdam, The Netherlands

Technicians from AkzoNobel and agroup of students from the Netherlands todayunveiled the race car they will be entering into this year's World SolarChallenge.

The Nuna7 solar-powered vehicle - which features pioneering pore-fillingtechnology - will take part in the competition in Australia in October,representing the fourth time that the Nuon Solar Team from the TechnicalUniversity in Delft and Sikkens paint experts from the company's AutomotiveandAerospace Coatings business have worked together.

This year, however, will be the first time that the Nuna has used the newcomposite pinhole filler Aerowave 2501, which has already been used oncommercial aircraft.

"When the carbon fiber shell of the Nuna is manufactured, the processcreatespinholes that must be filled with putty and then sanded, often multipletimes,"explained John Grevers, AkzoNobel's Technical Coordinator for Benelux andSikkens project leader for the Nuna.

"Our water-based pinhole filler replaces much of the putty and doesn'trequiresanding, because it can be easily wiped away. Which means it also adds lessweight to the car than traditional fillers."

As well as the new pinhole filler, the Nuna 7 also features anaerodynamicallyadvanced Sikkens coatings system designed to reduce wind drag and cut downonpreparation time. Products used include Colorbuild Plus, Autocryl Plus LV,andAutoclear LV Superior.

"AkzoNobel is helping us a lot in terms of making sure that we have thebestpossible aerodynamics thanks to the finish they provide," said LeslieNooteboom,the Delft team's Public Relations manager. "We feel that the company isplayinga very important role in our chances of winning the race in Australia."

Added Grevers: "It has been a valuable experience for us to developcoatingsthat not only provide advanced aerodynamics, but can also perform wellunder theextreme temperatures of solar car racing. And it's always good to work withstudents because they bring a fresh vision."

The team hopes to go one better than 2011, when the Nuna 6 finished secondinthe 11th World Solar Challenge. The biennial event - which aims to promoteresearch on solar-powered cars - attracts teams from across the globe. The2013race will be staged from October 6 to 13.
