Actron’s RUSTENZ Rust Preventing Capsule is a portable corrosion-protection capsule built to reduce rust. The capsule is designed to protect tools, metal and electrical components by creating an invisible, odorless, non-toxic, non-flammable presence around objects within a 2-foot radius of the capsule. Developed using Volatile Corrosion Inhibitor (VCI) technology, the RUSTENZ capsule emits corrosion-inhibiting molecules into an enclosure. This microscopic layer is a few molecules thick. The company says the product will not affect the electrical or mechanical properties or functionality of components.
