Zerust® Z-PAK® VCI packets emit a specially formulated VCI chemistry that quickly saturates and lands on metal surfaces located in the enclosure/packaging with the Z-PAK®. This molecular thin, temporary layer of VCI chemistry protects the metal surfaces from corrosion. Since the VCI chemistry is gaseous, hard-to-reach areas of the metal components – such as unobstructed inner surfaces, are also protected from corrosion when a sufficient amount of the VCI chemistry lands on them. Once the metal components leaves the enclosure/packaging, away from the Z-PAK®, the VCI chemistry on the metal surfaces volatilizes into the air. The molecular thin layer of VCI chemistry, even when present, will not affect the physical, chemical, or structural properties of the protected metal surfaces. Your customers can work on, painting, coating, welding, processing, and/or assembling the metal parts immediately upon receiving them at the facility from the shipment/storage.
Z-PAK® must be used inside an enclosure with limited airflow in order for the product to be effective. A few typical uses of Z- PAK® are:
• Use together with Zerust® ICT® plastic packaging for more robust corrosion protection – e.g. reduce corrosion risk for highly sensitive metals, provide better VCI diffusion in tightly stacked metal parts inside the packaging, etc.
• Inside sealed or obstructed voids that the Zerust® ICT® packaging is not able to protect.
• In enclosures of large equipment, that requires targeted corrosion protection for specific areas.
Note: Z-PAK® VCI diffuser chemistry is designed to be used for ferrous metal (Carbon Steel, Silicon Steel, Stainless Steel, Cast Iron) surfaces. In certain situations, Z-PAK® may be used for metal components containing limited yellow metal/parts but check with your Zerust® Account Manager before doing so.
