FEATURES
Provides up to 24 months of continuous protection in contact and vapor phases
Creates monomolecular inhibiting layer
Vapor phase inhibiting action protects inaccessible and recessed surfaces
If VpCI layer is disturbed by moisture or opening of the enclosed space, the layer is replenished by continuous vapor redeposition
Does not contain silicates, phosphates, nitrites, or heavy metals
Biodegradable
Little to no surface preparation is required
Easy to apply
When required, powder can be removed by blown air or water rinse
VpCI layer does not interfere with operation of mechanical components
Provides multimetal protection
Commercial equivalent to Mil Spec: MIL I-22110C

APPLICATIONS
Bottom plate protection of petroleum storage tanks
Tubular structures, pipes, and vessels
Internal surfaces of compressors, turbines, engines, tanks, boilers, and heat exchangers
Dry lay-up of closed circuit cooling systems
Equipment protection after hydrostatic testing
Cavities and void spaces on ships, barges, offshore platforms, sewage plants, dams, etc.

DOSAGE
VpCI-308/308 S protect up to 1 ft3 (28 liter) of enclosed space per 0.3-0.5 oz. (8.4-14.2 g) of powder (300-500 g/m3).
For wet application use 0.5-2% by weight. VpCI-308 is water soluble.
METHOD OF APPLICATION
Apply powder by dusting, fogging, or sprinkling. After application simply cover, close, or seal the interior cavity or void. VpCI-308 is also water soluble and can be used in wet applications.
Fogging is easily achieved with a low pressure air hose and sandblast cup, or converted wet-dry vacuum. Large conventional sandblasting systems can also be used.
METHOD OF REMOVAL
When required VpCI-308/308 S in powder form can be removed by using blown air or by a water rinse. Typically, when applied in aqueous form the product does not require removal.

PRECAUTIONS

Caking of powder may occur when it is exposed to moisture and then dried. The likelihood of this is increased when powder is exposed to high heat and multiple wet/ dry cycles. When powder gets caked, baked, and hard- ened it may require removal by mechanical means or by aggressive acid cleaning. To avoid caking of powder do not over apply or unevenly disperse the dry powder. In aqueous applications make sure the powder has been totally dissolved before using.

Powder is not soluble in hydrocarbon fluids. Rinse pow- der from vessels before adding hydrocarbon fluids.

Powder should be removed from the area prior to high temperature processing or welding.
