Cortec’s 329 D ES spray protects coils from corrosion

Cortec® Corp. has introduced VpCI®-329 D ES, a ready-to-use spray providing rust prevention for metals in indoor and outdoor sheltered conditions, including coils, gears, spindles, and any metal parts that require a light coat of oil for further processing and shipment.

The spray contains Vapor phase Corrosion Inhibitor (VpCI) technology, and its carrier is a combination of bio-based oil and mineral spirit. The oil-soluble corrosion inhibitors create a film that clings to metal surfaces to provide contact corrosion protection. VpCIs release into the air and attach electrochemically to the metal surface.

The coating provides corrosion protection to ferrous and nonferrous metals and performs in 100 percent relative humidity, as well as in the presence of corrosive species such as chlorides, hydrogen sulfide, and other sulfur compounds.
