This corrosion inhibitor tackles high-moisture conditions

| By Mary Page Bailey and Gerald Ondrey

VpCI-396 is a very hard but flexible corrosion-inhibiting coating that cures in high-humidity conditions. VpCI-396 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). This makes it a good option for structural steel and tanks in a chemical- or water-vapor-rich industrial environment. VpCI-396 can be used over this company’s CorrVerter Rust Converter Primer on previously rusted surfaces. — Cortec Corp., St. Paul, Minn.
