VpCI®-396 is a high solids aromatic moisture cure urethane. VpCI®-396 is a direct to metal primer for multimetal protection. VpCI®-396 should be top coated with an aliphatic urethane top coat for best results. In addition to the outstanding barrier protection, VpCI®-396 also contains Vapor phase Corrosion Inhibitors for additional protection. VpCI®-396 is suitable for immersed structures when applied over VpCI® CorrVerter® for marginally prepared surfaces; such as ballast tanks, storage tanks, or holding tanks containing hydrocarbons to high salinity solutions.VpCI®-396 forms a very hard, but flexible coating that cures in the presence of moisture in the air. For best results the curing conditions required are a relative humidity between 20% and 80% with temperatures above 32ºF (0ºC) and below 120ºF (50ºC).
