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.

  • Easy-to-use:  no surface preparation, compact/space-saving size
  • Simple to install:  place on flat surface or hang using zip tie or string
  • Safe, environmentally friendly, recyclable
  • Foam’s unique capillary action releases VCI at a controlled rate over a long period of time
  • One emitter covers up to 17-33 cubic feet of enclosed space
  • Multiple emitters can be used to prevent rust in larger spaces
  • Protects for up to 24 months
  • Mess-free rust prevention – no cleaning, wiping or degreasing of metal
  • Can be used alone or paired with other ARMOR VCI products for extended protection
  • Prevents rust without the use of oils, solvents or other harsh chemicals
  • Non-fibrous and ideal for use with mechanical or electrical components
  • Meets all REACH and RoHS requirements
