Oct 17, 2014· A protective oxide film of aluminum is only stable in a pH range of 4.5 to 8.5. 1 Chemical operations for the metal surface of aluminum include many process solutions that intentionally exceed this pH range for cleaning, metal removal and subsequent smut removal. These process solutions are formulated to avoid deleterious pitting or preferential etching.
According to EN 13523-0, a prepainted metal (or coil coated metal) is a ‘metal on which a coating material (e.g. paint, film) has been applied by coil coating’.When applied onto the metallic substrate, the coating material (in liquid, in paste or powder form) forms a film possessing protective, decorative and/or other specific properties.
Coil Coating pride. The process of coil coating started in middle of previous century and the benefits were seen quickly with many ways of application, from automobile to building industry. The technology is evolving day by day and so are the possibilities for the companies using coil coated aluminium and for those producing it.
