The Cortec EcoAir Tool & Die Rust Preventative is designed to meet the needs of mold, tool, and die manufacturers and end users by protecting tool steels during shipping, storage, and transportation. The liquid rust preventative comes in a non-flammable spray can and is safer to store than traditional flammable aerosols. It cleans grease, oils, adhesives, and water deposits off metal surfaces, as well as preserves all types of carbon or alloy-based tooling, molds, fixtures, and dies up to 24 months indoors.
