EXPERIMENTAL EVALUATION FOR POWDER COATING ON CHROMIUM-FREE CHEMICAL CONVERTED ALUMINUM ALLOY SURFACE

Environmental management for baking enamel coating system on aluminum alloy building materials Part3

Abstract

 Powder coating on aluminum alloy materials has not been popularized yet in Japan's construction industry field. Therefore, experimental evaluation for powder coating system with chromium-free chemical conversion has been continued in order to establish aluminum alloy surface coating system that takes into consideration environmental prevention. In this paper, experimental evaluations for the combination of several kinds of powder coating and some kinds of chromium-free chemical conversion are discussed.
