Enclosures Are Key

Zerust Capsules and Bags maintain their potency best within enclosures that limit air exchange with the outside atmosphere. However, the enclosures you use do not need to be 100% air tight like a gun safe.

Rifle bags, cabinets, display cases, toolboxes and other containers all serve to minimize air exchange and thereby help maintain a high concentration of Vapor Corrosion Inhibitors (VCI).

Higher concentrations mean increased effectiveness, so it is important to limit air exchange in order for the enclosed atmosphere to reach saturation levels of VCIs.

Position of Capsules In A Gun Safe or Enclosure

When possible, Zerust Capsules should be located in the center of an enclosure. The VC2-1 capsule is most effective within a 2 ft. radius from its location and in a volume of 33.5 cubic feet. If your enclosed area is larger than this, we recommend you use two or three capsules.

The approximate life span of one capsule serving 33.5 cubic feet of volume is 1 year. That’s what makes Zerust such a convenient and economical corrosion protection device.

Each Zerust Capsule has a convenient label to record the date when you place it in your storage enclosure.
