Premier supplier of high-quality engineered equipment for the wastewater industry
Corrosion management for drive housings and worm gearboxes
Reduce rust and corrosion on outer drive housing, and inner components of the worm gearbox during long ocean transit
Implemented Axxanol™ 707C VCI oil additive and ICT®510-OPS VCI film, eliminating corrosion on the outer and inner components of drive housings
A premier supplier of high-quality engineered equipment for the wastewater industry faced challenges with shipping new products to a Southeast Asia country. They needed a solution to protect large drive housings from rust and corrosion during their long ocean transit. Each drive housing also contained an enclosed worm gearbox which required additional protection as well since they would not be filling it with oil before shipping. They were looking for rust inhibiting solutions to protect the outer drive housing, which was 80” in diameter, and the inner components of the worm gearbox. All components in question were ferrous metals made from cast iron or high carbon steel and are known to be highly susceptible to rust from exposure to the ocean-atmosphere.
For the inside of the worm gearbox, it was decided that the best solution to protect the internal gear components was to use the ZERUST® Axxanol™ 707C VCI oil additive. They would be able to spray a small amount of the additive into the gearbox before closing the cap. The powerful VCI (Vapor Corrosion Inhibitors) from the Axxanol™ 707C will fill all the void space inside of the gearbox and protect the metal surfaces from rust and corrosion during shipping and storage. In addition, since Axxanol™ 707C was specially designed to be used with lubricating oils, the customer would not need to drain it before filling the gearbox with the required lubricating oil for use.
To protect the outside of the drive housing, it was decided that the best solution was to completely shrink wrap them using ZERUST® ICT®510-OPS (Outdoor Preservation Shrink) VCI film. This premium shrink film was selected due to its high-strength polyethylene resin formulation that also incorporated 3-year UV stabilizers and ZERUST’s proprietary VCI to protect ferrous metals from corrosion. In addition, the application of the ZERUST® OPS shrink film did not take any longer to implement when compared to the traditional non-VCI shrink film they were accustomed to using on the drive housings.
The customer’s recent first shipment from the Midwest of the United States to Southeast Asia was a success! No rust or corrosion was found on or inside the drive housing and worm gearbox. The customer will now implement these products and procedures for all future overseas shipments.

Axxanol™ 707C VCI oil additive is a vapor-phase-only corrosion inhibitor concentrate specially designed for use with lubricating oils. Furthermore, It provides corrosion protection of metal surfaces within the void spaces of closed systems, such as internal combustion engines, transmissions, gearboxes, hydraulic systems, or other sealed, lubricated systems.
ICT®510-OPS VCI Shrink Film is an 8-mil, high-strength shrink film integrated with ZERUST® Vapor Corrosion Inhibitor (VCI) technology and UV stabilizers, designed specifically for the long-term outdoor preservation of large assets.
Axxanol™ 710C is an anti-corrosion oil additive that protects using ZERUST® Contact Inhibitors and Vapor Corrosion Inhibitors (VCI). Furthermore, it provides corrosion protection of metal surfaces within the void spaces of closed systems, such as internal combustion engines, transmissions, gearboxes, hydraulic systems, or other sealed, lubricated systems.
ICT®510-SRK Film is polyethylene shrink film impregnated with Vapor Corrosion Inhibitors that shrinks tightly around the item when subjected to heat, providing a contoured fit and VCI protection.
