Rust Prevent Sealant

Rust Preventive & Corrosion Inhibitor | Rust Prevent™ 290

Industrial Non-Nitrite Rust Preventive & Corrosion Inhibitor. Rust Prevent™ 290 is a water-based, non-nitrite corrosion inhibitor that leaves a protective film on ferrous metals to guard against rust during processing, storage, and shipment. Applied at a 10:1 dilution, it delivers long-lasting protection across a wide range of metalworking and manufacturing operations. Its combination of corrosion-inhibiting chemicals helps prevent rust on all ferrous materials.
