Cortec awarded new US patent for innovation in VCI film technology


Cortec has been awarded yet another patent for innovation in the field of VCI (Vapour 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.

Vapour phase Corrosion Inhibitors in the film vaporise 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:

  • Aluminium
  • Galvanised Steel
  • Carbon Steel
  • Silicon Steel
  • Stainless Steel
  • Copper
  • 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 30ft (9.1m) 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.

EcoShield®VpCI®-226 Film and Bags are an excellent 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 are also outstanding materials for 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 custom high-dollar 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.
