Recessed spaces are easily missed by common corrosion inhibitors leaving areas exposed to the dangerous effects of corrosion. Cortec Corp. has introduced EcoFog VpCI-309 Nano to reach these hidden areas. This patent pending product is a Vapor phase Corrosion Inhibiting (VpCI) powder designed to protect ferrous metals in hard-to-reach recessed areas, interior cavities, and voids. Due to its submicron particles, it diffuses faster, travels longer distances, and has a much larger specific surface area compared to a product with larger sized particles. EcoFog VpCI-309 Nano offers VpCI protection with unique physiochemical advantages, making it an extremely efficient method to treat hard-to-reach spaces within an enclosed space. The material uses Cortec’s VpCItechnology to provide a monomolecular inhibiting layer on products. The powder is easy to apply with little or no surface preparation needed and provides superior protection to ferrous metals including carbon steel, stainless steel, and aluminum. This product does not contain silicates, phosphates, nitrites, or heavy metals and provides up to 24 months of continuous protection. EcoFog VpCI-309 Nano does not affect the physical properties of the product and can be removed by air gun or water rinse.
