Product Description

Product Description

ZERUST® ICT®520-CSL streamlines packaging operations by removing the need for heat sealing, taping, or stapling. As a result, it saves time, equipment, and labor. Its unique self-adhesive property allows the film to bond to itself, forming a secure closure within seconds without leaving any residue on the protected items. Furthermore, ICT®520-CSL Cold Seal Film diffuses invisible, odorless, and non-toxic ZERUST® Contact and Vapor Corrosion Inhibitors (VCI) that settle onto exposed metal surfaces inside the packaging or enclosure. Once removed from the packaging, the VCI will dissipate from the metal surface, allowing immediate painting, welding, or further processing.

Use ZERUST® Cold Seal Film to protect bare metal parts, such as gears, differential units, axle ends, and more, from rust and corrosion for years. Additionally, for added protection in challenging environments, ZERUST® VCI Film may be used with ZERUST® VCI diffuser products. Engineered for a broad range of applications, ICT®520-CSL is available in a multimetal protection formulation with custom sizes, ensuring an ideal packaging solution. Whether in storage or transit, ZERUST® ICT®520-CSL Cold Seal VCI Film delivers unparalleled performance.
