Part2.Performance of the Paintings after 4 Years Outdoor Exposure Test

Abstract

The authors have developed new fluoro-painting system for PCa panels.The character of this new system is high durability,low contamination and proper little elasticity.In this paper,the test result of performances of new system after 4 years outdoor exposure test at actual scale PCa panel is described.As a result,it was clarified as follows.(1)For light-weight PCa class1,there weren't crack at surface of film of new system but there were thin cracks less than 0.1mm at surface of PCa panel.(2)Adhisive strength of new system for PCa panel after 4 years was 3-4N/mm2.
