Toward a 100 Year Bridge Coating System: Bridge Topcoats in Japan

Fluoropolymers have been used as topcoats for bridges in Japan for more than 30 years. Based on extensive laboratory testing and long term results from the field, these materials are now required as topcoats on all bridges in Japan. Properly applied, fluorinated topcoats can increase coating system life to more than 60 years, with a goal of 100 years of topcoat life. These fluoropolymer topcoats offer substantial reductions in life cycle costs compared to conventional coating systems. This paper will discuss test results from both field and laboratory studies demonstrating the long term durability of fluorinated topcoats. Surface preparation and coating application methods used in Japan will be reviewed. Finally, the life cycle cost advantages of fluorinated topcoats will be shown.
