VpCI®-608 is a Vapor phase Corrosion Inhibitor powder for corrosion protection of ferrous metals in recessed areas, interior cavities and voids, such as double bottom in storage tanks.
Description
VpCI®-608 provides an extremely efficient dry or slurry method to protect metals within an enclosed space. The VpCI® vaporizes and adsorbs on all metal surfaces, reaching all exposed areas, including recessed sections and interior cavities.
FEATURES
• Works with or without cathodic protection
• Does not contain phosphates, nitrites or heavy metals
• Provides continuous protection
• Provides monomolecular inhibiting layer
• Vapor phase inhibiting action protects inaccessible and recessed surfaces
• Protected products can be shipped to customers without removing powder
• If VpCI® layer is disturbed, the layer is replenished by continuous vapor redeposition
• Little or no surface preparation is required
• Prevents further corrosion of pre-coated and painted surfaces
• Easy to apply
• VpCI® layer does not need to be removed prior to processing or use
• Easily removed by air gun or water
• Accepted by Florida DEP (Department of Environmental Protection) as an alternate procedure to cathodic protection
APPLICATIONS
• Double bottom of storage tanks floors
METHOD OF APPLICATION
New Tanks & Floor Replacement anks & Floor Replacement After tank pad construction is completed, VpCI®-608 powder should be applied at the rate of 1-2 Kg/10m² (2-4 lbs/100ft²). It should be spread evenly onto the tank pad. The floor plates can then be fabricated as normal. The VpCI slowly distributes itself uniformly throughout the base. At welds a small amount vaporizes, but condenses after cooling of the metal. In the case of a concrete tank pad, VpCI®-608 is applied to the surface, or a modified form is mixed into the wet concrete.
Existing Tanks
1. Application of VpCI’s in a powder form at the tank floor – tank pad interface.
2. Pumping liquid VpCI® slurry in the area between a tank floor and a lower floor or containment liner.
