Tackling High-Moisture Conditions With Micro-Corrosion Inhibiting Coatings
ST PAUL, MN — There are two main challenges facing protective coatings in high-moisture conditions. One is the issue of durability in a moisture-laden or immersion environment that is naturally more corrosive than a dry environment. Another issue is the challenge of being able to properly cure a coating in the presence of moisture. Cortec’s Micro-Corrosion Inhibiting Coatings™ provide options when facing these elevated moisture problems.
VpCI®-396 is a very hard but flexible coating that cures in conditions of high humidity. It is a solvent-based, moisture-cure urethane that can be used as a direct-to-metal (DTM) primer and in some cases a topcoat. It provides protection in harsh, outdoor, unsheltered applications and cures best when applied under relative humidity of 20-80% with temperatures ranging from 32-120 °F (0-50 °C), making it a good option for ballast tanks or structural steel and tanks in a chemical- or water-vapor rich industrial environment.
