ElectriCorr VpCI-238 is an electronic cleaner containing Vapor phase Corrosion Inhibitor (VpCI). This cleaner is specifically formulated for electrical/electronic equipment, and components.ElectriCorr VpCI-238 forms a thin film of Vapor phase Corrosion Inhibitors effective against aggressive environments including industrial, marine, and tropical climates. This film does not alter the electrical resistance or magnetic properties of metal substrates. ElectriCorr VpCI-238 can be safely applied to protect circuits or relays without causing any changes in conductivity. It can be safely used with most plastics, elastomers, and other non-metallics.
