In June 2020, Cortec has been awarded a patent for innovation in the field of VCI (Vapor Corrosion Inhibitor) science. The new patent covers Cortec's EcoShield VpCI-226, a 100% nitrite free film that protects metals from corrosion.
Over the course of 43 years, Cortec® has received more than 60 patents. Several VCI films from Cortec® have been awarded, like VCI films with recycled content, biodegradable VCI films, and VCI films with fire retardant additives.
The latest awarded technology, the EcoShield® VpCI®-226, protects metal parts against salt, excessive humidity, condensation, moisture, aggressive industrial atmospheres, and dissimilar metal corrosion. In fact, the 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, such as 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.
Application fields of EcoShield® VpCI®-226
EcoShield® VpCI®-226 Film and Bags are a resource for manufacturers who need packaging materials that will protect small to large metal components—such as auto parts, bearings, brake disks, firearms, castings, or finished equipment, etc.—from corrosion in-process or in transit to the assembly plant or end user.
They find application also in industries facing facility or equipment layup or construction delays. For example, new power or gas plants under construction can use EcoShield® VpCI®-226 Film and Bags to protect assets that arrive onsite long before plant commissioning. Online facilities can also use EcoShield® VpCI®-226 Film and Bags to protect critical and operational spares that need to be ready for use at a moment's notice.
