Ultra-Weatherable Fluoropolymer Coatings for Bridges

摘要

Fluoropolymer topcoats have been used on bridges in Japan for more than 25 years. Based on data from field applications and laboratory testing, these topcoats can have an effective life exceeding 50 yeara The use of fluorourethane topcoats can substantially reduce life cycle costs for coatings on steel and concrete bridges. Fluoropolymer topcoats are now required in Japan on large steel bridges like the Akashi Straits Bridge, the world's longest suspension bridge.
