Environmental Management for Baked Enamel Coating System onto Aluminum Alloy Building Materials

Part14 Experimental Evaluation by Outdoor Exposure Test for Various Coating Systems

Abstract

In previous announcement (No. 11), I described assessment upshot for test 18 months and 9 months of environmental management for baked enamel coating system started in 2008 years and 2009 was considered and reported it about the painting specification which could be applied.This report enforced assessment for outdoor exposure test 9 months of which used medicine marketed afresh in outdoor exposure test 30 months and 21 months and 2010 that passed furthermore for 12 months.As a result, as for the painting specification which applied the conversion treatment which did not include Cr, there is variance in engine-performance by kind of medicine and reports it because it became clear that even identification medicine was missed in stability.
