Cortec VpCI-105 emitters are unique devices designed to provide corrosion protection for metal components and parts enclosed in non-ventilated control boxes, cabinets, or tool boxes up to 5 cubic feet (141.6 liters). The VpCI-105 device emits Vapor phase Corrosion Inhibitors (VpCIs), which form a protective coating on all metal surfaces. VpCI-105 is a patented plastic emitter with a breathable Tyvek membrane through which the corrosion inhibitor is released. It provides long-term protection against corrosion even in the presence of adverse conditions including salt, moisture, airborne contaminants, H2S, SO2, NH3, and others. 20 emitters per carton. Each emitter measures 2.25" in diameter x .75" high. Typical Applications: Packaging and storage electrical equipment Marine navigation and communication electronic equipment Aerospace electrical controls Electric motors Switching equipment Fuse boxes and power boxes Medical equipment Electrical wireways and terminal boxes Scientific and measuring instruments Telecommunications equipment Remote electronics devices Hand-held battery-operated devices Tool-boxes, gun safes, and any other enclosure for metal storage Features: Economical to use Provides continuous protection for up to 24 months Effective in polluted and humid environments Does not interfere with electrical, optical, or mechanical surface properties Multimetal protection Quick and easy installation Protects during operation and shutdown Non-toxic and safe to handle Compact, space-saving, and unobtrusive device Free of nitrites, hylogens, and phosphates No spraying, wiping, or dipping required Low VOC values Meets Southern California Clean Air Act and other National and local re
