Cortec’s VpCI-368 coating now has the addition of extra vapor phase corrosion inhibitors. Designed to provide protection to metal substrates exposed to harsh outdoor conditions, the dark brown viscous liquid dries into a firm moisture-displacing wax-like film that can be removed by mineral spirits or alkaline cleaners such as Cortec’s own VpCI-414. The film can be used for a variety of applications where heavy-duty corrosion protection is needed.
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.
