ARMOR SHIELD® CF33 Emitters combine VCI (vapor corrosion inhibitor) with reticulated foam to protect metal from corroding for 12-24 months, depending on air flow and conditions.  Each CF33 emitter has a rust-prevention coverage area of 17-33 cubic feet of enclosed space, based on where it is placed.

VCI (vapor corrosion inhibitors) is a class of chemical compounds that emit rust-inhibiting vapors into an enclosed air space such as a bag, box, crate or storage container.  The VCI molecules form a layer of protection on the surface of metal that displaces moisture and prevents metal from corroding.  ARMOR VCI Nanotechnology™ is our unique formulation of VCI — it’s the “secret sauce” we use in all ARMOR VCI rust prevention products to keep metal parts clean and rust free while they are in process, in storage or in transport.
