Abstract:
Zinc-rich organic coatings, with and without topcoats, were exposed at a 6000 foot depth in the Pacific Ocean for six months duration. Two air-dried zinc-rich epoxies, without topcoats, and one of these with an air dried epoxy topcoat, blistered during the six months of exposure. In contrast zinc-rich catalytically cured epoxies, with or without catalytically cured epoxy or coal-tar epoxy topcoats gave excellent protection to steel test panels. Also, a zinc-filled modified orange saran gave excellent protection to steel panels for six months in the deep ocean. Modified white saran topcoats did not improve the protection given by the zinc-filled modified orange saran. Author
