Aceelerated degradation coating of outdoor exposure test in Nansei Islands in south of 28 degrees north latitude

Abstract

In this paper, Accelerated degradation coating of outdoor exposure test in Nansei Islands in south of 28 degrees north latitude is discussed on results at defference angles in Okinawa and Aichi Prefectures. Main results in this paper are as follows. (1)The result in Okinawa of solvent type thermoplastic fluorocabon coating and thermosetting fluorocarbon powder coating at the angle of 27 degrees becomes double the deterioration at the vertical. (2) Two layer sepalation type composite resin powder coating maintains high gloss retention rate in the outdoor exposure tests. The powder coating has superior weatherabity than above coatings. Therefore, the outdoor exposure test is continued. (3)Solvent type thermoplastic fluorocabon coating and thermosetting fluorocarbon powder coating in exposure test results in Aichi retains higher gloss than in Okinawa.
