Abstract
As a study about the durability of various coating systems which were surface treatment of aluminum used as sash and curtain wall cladding of the building, outdoors revelation examined nine kinds of 15 total articles of air drying coating systems (four kinds of eight articles) and baking finish coating systems (five kinds of seven articles) for 25 years. During this revelation examination, I measured the appearance change, stain, chalking, adhesion, color difference, gloss degree, film thickness of various coating systems. In addition, I carried out the surface analysis by SEM / EDX / FT-IR of the coating which I gathered from the examination body surface after the outdoor revelation end. Based on these outdoor revelation examinations / measurement results, I evaluated the weatherability various coating system articles of nine kinds of 15 total articles of air drying coating systems and baking finish coating systems which I held as an examination object.
