Development of a non chromated, Reach’s compliant anodic electropaint, with very low volatile organic compounds, for high protection against electrochemical corrosion of pickled aluminium alloys used (Cr free Epaint)
Date du début: 1 oct. 2010, Date de fin: 31 mai 2014,
The current way of protecting aluminum alloys used for structural components of aircrafts consists in:o using a surface anodizing pretreatment (hazardous chromated pretreatment still often used)o then spraying either a chromated solventborne paint or a chromated waterbased paint. With this process of application, hazardous oversprays (containing chromates) are important and only 40% in average of ...
