Abstract: The research of a new anticorrosive coating system for navy ship hulls is described. The coating system consists of the anticorrosive primer (fast drying water-based inorganic silicate zinc coating or organic zinc-rich coating), the barrier type tie coating and the special optical finishing. The system is screened out by a series of tests including traditional performance test, accelerated test, the system compatibility test, the simulated-panel test exposed to the sea and the ship application test. The results indicate that the system is superior to that of the existing system in protective performances and is complied with the new navy requirements in optical properties.
