Packaging as Temporary Corrosion Protection
Multfunctional Film Protects against Aggressive Environments
The non-toxic VpCI-126 EM UV Film from Cortec Corp., St. Paul, MN/USA, combines high strength resins with ultraviolet light stabilizers (UV) and vapor phase corrosion inhibitor (VpCI) technology. VpCIs are agents that vaporize and saturate enclosed spaces with their vapors. The VpCl molecules then condense on the bare metal surface, forming an invisible monomolecular protective film. Due to their polarity, they inhibit the destructive electrochemical corrosion reactions.
According to the manufacturer, this state-of-the-art film technology provides effective multi-metal protection for parts, equipment, and vehicles for up to three years. It provides contact, barrier and vapor-phase corrosion protection even in very aggressive outdoor conditions. Unlike commercial anticorrosion films that rely on white pigments to reflect UV light, VpCI-126 EM UV contains unique inhibitors that protect the polymer from UV exposure and prevent degradation.
This economical film eliminates disposal costs and is ideally suited for transit, staging, and lay-up of critical equipment; including equipment with large void spaces, multiple metals and complex geometries. According to the manufacturer the film is a safe and improved replacement for harmful conventional rust preventatives such as oils and desiccants. Parts protected with the new film are ready to use with no additional cleaning and/or degreasing necessary. The film is also transparent, making it easy to identify parts without compromising your package.
Metal parts packaged in VpCI film receive continuous protection against salt air and humid environments, moisture, aggressive industrial atmospheres and dissimilar metal corrosion. The VpCIs vaporize and condense on all metal surfaces within the enclosed space. VpCIs diffuse to every area of the part, protecting its exterior, as well as void spaces and recessed areas. Equipment is completely protected from corrosion during storage, lay-up and staging as well as during domestic and overseas shipments.
Besides its contact, barrier and vapor-phase corrosion protection, the film can be used with other Cortec products to provide total turnkey preservation for long term storage.
VpCI-126 EM UV Film is RoHS compliant and conforms to Nace Standard RP 0487-2000, ASTM D 6988, D 882-02, D 1922-06a and D 1709-04.
