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

Part 2 Experimental evaluation for powder coating

Abstract

Two technological problems on surface treatment of aluminum alloy building materials have been indicated. One is disuse of the chemical conversion reagent which contains chromium VI. The other is new application of powder coating that excludes organic solvent. In the Japanese construction industry fields, the application of the powder coating has not yet been popularized. In this paper, experimental evaluations for the powder coating system with chromium-free chemical conversion are discussed.
