Herbol-Symbiotec is the result of many years of development collaboration between Akzo Nobel and BASF. “It is extremely important for us to have found as experienced and competent a partner as Akzo Nobel to market our innovative COL.9 binder”, says Jan-Peter Sander, head of BASF’s Adhesive and Construction Polymers regional business unit and thus responsible for the architectural coatings business in Europe. BASF and Herbol have signed an exclusive co-branding for COL.9 until the end of 2007. Ernst Häring, head of Research and Development at Akzo Nobel in Cologne, emphasizes: “Herbol-Symbiotec will allow us to further expand our position as innovation leader in architectural paints and coatings. With the help of our partner BASF, we have for the first time succeeded in combining the advantages of organic and inorganic coatings in a single product – that is a huge success.” The Max Planck Institute of Colloids and Interfaces in Potsdam, near Berlin, has certified that Herbol-Symbiotec is a genuine nano facade coating.

"After several years spent passing through BASF's development laboratories, the first COL.9-based facade coating is now on the market: Herbol-Symbiotec® from Akzo Nobel. "This new flagship of our extensive range of coatings, freely available from specialized trade outlets since early 2008, is the result of successful cooperation between Akzo Nobel and BASF," says Andreas Götz, Head of the Deco Application Technology Laboratory at Akzo Nobel. Before the coating, which consists to about one half of COL.9, could be launched on the market, Herbol-Symbiotec again passed through an intensive development phase which was completed in 2007 with a broad-based practical trial by selected professional painters and an expert evaluation by the Max-Planck Institute of Colloids and Interfaces in Potsdam near Berlin. "Using electron microscopic techniques, we were able to fully confirm the composition stated by Akzo Nobel, especially the nanoparticles embedded in larger polymer particles," says Prof. Dr. Markus Antonietti, Director of the Institute's Department of Colloid Chemistry. "After drying, nanostructures known to be dirt repellent form on the surface of the coating."
