Cortec Expands VCI Technology for Metal Corrosion


Cortec has been awarded yet another patent for innovation in the field of VCI (Vapor Corrosion Inhibitor) science. This new patent, awarded in June 2020, covers Cortec’s latest film technology, EcoShield VpCI-226, a 100% nitrite free film that protects metals from corrosion. It follows a significant line of other VCI film patents that Cortec has been awarded over the years for VCI films with recycled content, biodegradable VCI films, and VCI films with fire retardant additives. This is another one of more than 60 patents that Cortec has been received in 43 years and demonstrates Cortec’s dynamic position on the leading edge of VCI technology innovation!

Metal parts packaged in EcoShield VpCI-226 receive continuous protection against salt, excessive humidity, condensation, moisture, aggressive industrial atmospheres, and dissimilar metal corrosion. Vapor phase Corrosion Inhibitors in the film vaporize and condense on metal surfaces in the enclosed package, protecting exterior as well as hard-to-reach interior surfaces. EcoShield VpCI-226 provides complete product protection during storage as well as during domestic and overseas shipments, virtually eliminating rust claims. It protects multiple metal types including aluminum, galvanized steel, carbon steel, silicon steel, stainless steel, copper, and brass.

EcoShield VpCI-226 Film and Bags are available in many different sizes and constructions, from small top-seal bags that protect nuts and bolts to 30 foot (9.1 m) wide sheeting for storing large industrial equipment. They are non-hazardous and recyclable and can be manufactured using a wide array of the most advanced resins. Custom blends are available to provide the exact properties needed, whether improved puncture resistance, tear strength, or other requirements. EcoShield VpCI-226 Film and Bags replace conventional rust preventatives such as oil and desiccants, saving time and hassle by eliminating all the degreasing or coating removal required in the past.
