FEATURES
• Does not contain silicates, phosphates, nitrites, secondary 
amines, or heavy metals
• Provides up to 24 months of continuous protection
• Creates monomolecular inhibiting layer
• Vapor phase inhibiting action protects inaccessible surfaces
• If VmCI layer is disturbed by moisture or opening of the enclosed 
space, it will be replenished by continuous vapor redeposition
• Easy to apply
• VmCI layer does not need to be removed prior to processing or 
use in most cases
• Powder is easily removed by air gun or water
• VmCI layer does not interfere with operation of mechanical 
components
• Provides multi-metal protection
• Commercial equivalent to MIL I-22110C
• NSN 6850-01-632-7695
APPLICATION
• Bottom plate protection of above-ground petroleum storage 
tanks
• Tubular structures, pipes, and vessels
• Internal surfaces of void spaces such as 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. 
METHOD OF APPLICATION
Apply powder by dusting, fogging, or sprinkling. After application 
simply cover, close, or seal off the interior cavity or void. Fogging 
is easily achieved with a low pressure air hose and sandblast cup. 
Large conventional sandblasting systems can also be used. VmCI￾307® can be easily removed by using a low pressure air gun or 
water rinse.
Precautions: VmCI-307® has a tendency to clump and form chunks 
in the packaged drum. Clumping does not affect the performance 
of the inhibitor. Large clumps of powder can be broken apart and 
used as normal.
• Powder is not soluble in hydrocarbon fluids. Rinse powder from 
vessels before adding hydrocarbon fluids.
• Powder should be removed from the area prior to high tempera￾ture processing or welding.
Protects up to 1 ft3 (28 liter) per 0.3-0.5 oz. (8.4-14.2 g) of powder 
(300-500 g/m3) of interior space.
