International Classification:

C09D 508

US Classification:

106 1429

Abstract:

This invention relates to a soft coating for ferrous metal surfaces tanks, having a thickness of about 1-10 mils, comprising over-based alkaline aliphatic-aromatic organic sulfonate salt, an alkaline earth metal or zinc salt of a naphthalene sulfonate, a drying oil, a metal drier, and a paraffinic oil. The coating is particularly useful for coating ferrous metal surfaces, such as ballast tanks, which are exposed to seawater. The invention also relates to a process for inhibiting the corrosion of ballast tanks.
