Akzo Nobel secures license for primer technology

Akzo Nobel's Aerospace Coatings business (ANAC) has announced that it is the first to develop products to contain breakthrough chromate-free technology following the signing of a commercial licensing agreement with the North Dakota State University Research Foundation (NDSU).
Researchers at NDSU have developed new primer technology for coating aluminum aircraft structures which is based on magnesium, rather than chromate (a harmful substance which is highly regulated in the U.S. and is coming under increasing pressure in Europe). This corrosion inhibiting technology - the first to be just as effective as chromate, according to the company - will now be incorporated into some of Akzo Nobel's aerospace coatings products.
Chromate-free primers have existed for many years, but despite being more environmentally-friendly, none provide the anti-corrosive properties of chromate, which is highly effective at inhibiting corrosion of the high strength aluminum alloys used to manufacture aircraft.
