ENVIRONMENTAL MANAGEMENT FOR BAKING ENAMEL COATING SYSTEM ON ALUMINUM ALLOY BUILDING MATERIALS

Recently, demand on the global environmental management and human health and safety is getting big worldwide social problem. Harmful substances influence on human health and safety. In Japanese construction industry fields, chemical conversion with chromium VI reagent in surface preparation process and solvent type paint in coating process have been applied to surface finishing on aluminum alloy building materials. Against the backgrounds, Japan Society for Finishing Technology has been studying these themes since 2006. In this paper, experimental evaluation measures for the surface preparation are discussed on experimental results.
