MIL-PRF-3420 Class 1, Style A VCI Paper | Nox-Rust® Vapor Wrapper 7090

Designed and tested to meet the U.S. Department of Defense’s MIL-PRF-3420 specification, Nox-Rust® 7090 delivers powerful, long-lasting corrosion protection for steel and other ferrous components. As a Class 1, Style A material, this VCI paper is made from a flat kraft carrier saturated throughout with Daubert Cromwell’s proven ferrous VCI chemistry—ensuring uniform protection across every square inch of the sheet. The corrosion inhibitors embedded within the fibers volatilize and form an invisible molecular layer on metal surfaces, blocking moisture, oxygen, and contaminants that cause rust during storage, shipment, and long-term preservation. This makes 7090 ideal for wrapping heavy parts, tools, machinery, and equipment deployed in military and government supply chains.
