It’s Shield-Shaped to Warn Rust and Corrosion that ARMOR VCI is on Duty

Look to the ARMOR SHIELD® CF33 Corrosion Inhibiting Emitter (we call it the Shield for short), in its signature shield-shape, to protect ferrous and non-ferrous metals from rust and corrosion. We combined the rust-preventing power of ARMOR’s proprietary VCI Nanotechnology™ (a.k.a., our “secret recipe” for vapor corrosion inhibitor) with open-cell polyether foam to produce the Shield, an emitter that protects against corrosion for up to 33.5 cubic feet with an effective reach radius, in all directions, of two feet. As an added bonus, the Shield has a controlled emission rate to allow for even and continuous protection.

Use this little-badge-of-rust-eradication in enclosed, non-ventilated areas such as electrical cabinets, HVAC rooms, control boxes, utility boxes, gun cabinets, or export containers. It is also effective where other VCI packaging materials are not possible or practical such as in returnable trays, containers or long-term storage applications.
