Shrink film market is expected to rise at a compound annual growth rate of more than 6% for the forecast period of 2021-2029. This rise is mostly attributable to increasing packaged goods consumption as a result of lifestyle changes.  Best seller from EcoCortec plant, Cortec’s patented, VpCI®-126 HP UV Shrink film, combines high strength resins with ultraviolet light stabilizers (UV) and Vapor phase Corrosion Inhibitor (VpCI®) technology. This shrink film provides multi-metal protection for parts and equipment for up to three years even in most aggressive outdoor conditions. Unlike some preservation films that rely on white pigments to reflect UV light, VpCI®-126 HP UV is transparent; containing unique inhibitors that protects the polymer from UV exposure and prevents degradation. VpCI®-126 HP UV can be applied in numerous applications. It is ideally suited for transit staging, and lay-up of critical equipment; including equipment with large void spaces, multiple metals, and complex geometries. It is an excellent replacement for conventional rust preventatives such as oils and desiccants, making equipment ready to use with no additional cleaning and or degreasing necessary. This will save our customers a lot of their valuable time and money.

VpCI®-126 HP UV Shrink Film, in conjunction with other Cortec®’s products, provides a total turnkey preservation for long-term storage. Metal parts packaged in VpCI®-126 HP UV Shrink Film receive continuous protection against salt air and humid environments, moisture, aggressive industrial atmospheres, and dissimilar metal corrosion. The VpCI’s vaporize and condense on all metal surfaces within the enclosed space; and diffuse to every area of your part, protecting its exterior, as well as void spaces and recessed areas.

Features:

  • Multi-metal corrosion inhibition providing contact, barrier, and vapor phase protection.
  • Will shrink using a wide variety of shrink tools including electric and propane heat guns
  • Recyclable and non-toxic

Protection of Wind Turbine Shafts, Rings and Hubs

Cortec, corrosion protection
A major Spanish wind energy component manufacturer of shafts, rings, and hubs for wind turbines uses Cortec VpCI materials to protect its products.

Major Spanish wind energy component manufacturer makes makes shafts, rings, and hubs for wind turbines and continuously ships them all over the world from various locations in Spain. They  experienced problems with corrosion and needed a system that would protect the components from corrosion for two to five years in indoor and outdoor conditions. The components were first given a thorough cleaning with VpCI®-415 (dilution in water) as needed to remove any dirt or grime. After drying, the most sensitive metal surfaces were coated with VpCI®-368 D removable coating at 50-75 µm (2-3 mils) wet film thickness using a roller. Finally, each element was wrapped and heat shrunk in either VpCI®-126 HP UV Shrink Film or MilCorr® VpCI® Shrink Film, depending on length of protection needed. The components were shipped out along with VpCI®-414 as part of a complete kit to clean off VpCI®-368 D at the destinations when required. After testing Cortec® VpCI® materials, the customer ultimately decided to incorporate them into their new wind turbine projects to avoid corrosion problems from the past as they were extremely satisfied with their performance.

Green solutions – latest developments in corrosion protection environmentally safe packaging

European EcoCortec® plant is located in Croatia and specializes in production of sustainable corrosion protection packaging under the license of its mother company, Cortec Corporation. It has been promoting safe, environmentally sustainable packaging solutions for more than 15 years. The plant offers films, papers, and bags, mostly  from renewable, biobased and recyclable materials. VpCI® film has already had a large impact on making corrosion protection more environmentally friendly by reducing the need for traditional hazardous rust preventatives. From highly effective film and foam technology to premium custom converted papers, EcoCortec® plant exports its wide range of products all over the world.
