THE SIMULATION STUDY OF ACTUAL MARINEATMOSPHERIC EXPOSURE AND INTERIOR ACCELERATEDTEST FOR MARINE COATING SYSTEMS

摘要

The paper describes the simulation work on accelerated testing in lab and exposure test inrnmarine atmospheric environment two year. The accelerated testing methods in lab includernUV-condensation and salt-fog alternative test and Xenon-Arc exposure testing. The marine coatingrnsystems are contained of polyurethane and acrylic. Compared with color difference and rate ofrnlosing-gloss of these topcoats, we can investigate the effect for coating surface performance caused byrnthese test. The result shows that the acceleration of UV-condensation and salt-fog alternative test canrnsimulate the actual marine atmospheric environment than the Xenon-Arc exposure testing.
