About Vapor-Inhibiting Ability Of VCI Materials Testing Services

A chemical substance that acts to reduce corrosion by a combination of volatilization from a VCImaterial, vapor transport in the warm, moist atmosphere of an enclosed environment, andcondensation onto surfaces in the space, including adsorption, dissolution, and hydrophobiceffects on metal surfaces, where the rate of corrosion of metal surfaces is thereby inhibited;also called vapor corrosion inhibitor, vapor-phase inhibitor, vapor-phase corrosion inhibitor, andvapor-transported corrosion inhibitor. [NACE TM-0208]

Volatile Corrosion inhibitors are simplified means of corrosion protection for enclosed packagesand metal cavities. Commonly known by several names as vapor corrosion inhibitor, vapor-phaseinhibitor, vapor-phase corrosion inhibitor, and vapor-transported corrosion inhibitor. NACE TM 0208is a qualitative test method to evaluates the vapour inhibiting ability (VIA) of volatile corrosioninhibitors (VCI). Several different forms of volatile corrosion inhibitors can be evaluated usingthis method..
