Evaiuation for powder coating on aluminum alloy building materials

Part5. Summary of investigations into the actual conditions in overseas buildings

Abstract

Recently, powder coating that reduces environmental pollution because of no volatile organic compounds has been considerably noticed as alternative solvent type coating in Japanese construction industry fields. However, it has been begun to apply to interior finishing and it is rare to apply to exterior in the present Japanese construction. On the other hands, it has been popularized in overseas countries and over 10 years has been already passed from building completion. Durability has to discuss in order to popularize in Japanese construction. Therefore, investigation into the actual condition in overseas buildings has been executed. A main fruit of this research is the following. The powder coated building exterior has not visually remarkable deterioration and also it would be expected enough durability in application to Japanese building exterior.
