VpCI-368 EVP (Extra Vapor Protection) is also available for application in complex, sealed spaces where a greater concentration of vapor inhibitor is beneficial. The extra dose of Cortec VpCI vaporizes from the coating, fills the enclosed space, and adsorbs on difficult-to-reach surfaces. This is helpful on applications such as pipe internals where it is challenging to thoroughly cover all metal substrates.
VpCI-368 EVP coating is said to be flexible and offers excellent outdoor protection that is much easier to handle and remove than traditional wax-based coatings commonly used in military and similar applications. VpCI-368 EVP is UV resistant and passes 900-1500 hours of ASTM B-117 intense salt spray testing applied at 2-3 mils on carbon steel.
