The VCI Emitter Disks is a lightweight disk that contains corrosion inhibitors to provide a corrosion-free environment. The corrosion inhibitor adheres to the metal surfaces, preventing salt, dirt, moisture, oxygen and other contaminants from settling on the metal surfaces. Designed to be slim and compact, this allows the emitter to access tight and restricted spaces. Adhesive tape allows VCI Emitters Disks to stay firmly on metal surfaces, walls and cabinets. The unique nature of the corrosion inhibitor is formulated for steel and multi-metal parts. Capable of providing lasting protection for years even in humid conditions, VCI Emitter Disks are safe, easy to use and economical.
