VpCI®-609 is a water-soluble V a p o r p h a s e C o r r o s i o n Inhibitor (VpCI ®) powder for wet or dry corrosion protection of ferrous metals and aluminum. VpCI®-609 is also available as VpCI®-609 S (with silica)
FEATURES
• Accepted by Cefas as an offshore chemical. Registered under OCNS number 25717
allowing use at 5,000 ppm
• Provides liquid, vapor-phase, and interface protection (above the liquid level)
• Creates a monomolecular inhibiting layer on metal surface
• Provides up to 24 months of continuous protection
• Does not contain nitrites, phosphates, or heavy metals
• Passes Vapor Inhibiting Ability Test (NACE Standard TM0208-2008) before and
after Exhaustion Test (MIL-STD-3010C)
• UFI: 3U20-J0EA-E002-G43C
ADVANTAGES
• Vapor-phase inhibiting action protects inaccessible and recessed surfaces
• If the VpCI® layer is disturbed by moisture or the opening of an enclosed space,
the layer is replenished by continuous vapor redeposition
• Prevents future corrosion of precoated and painted surfaces
• VpCI® layer typically does not need to be removed prior to processing or use
• If required, powder is easily removed by air gun or water flush
• Does not increase alkalinity
• Provides economical protection for very large applications
TOXICOLOGICAL TESTING RESULTS (Performed by Nortech A.S. (Norway))*
• Biodegradability: 100% biodegradable in marine environment, rapidly degradable
substance (OECD** 306, BOD 28 Marine test)
• Toxicity: Very low (LD-50 = 5,000 mg oral-rat)
• Bioaccumulation potential: none (OECD Guideline 117)
*Testing performed in accordance with Oslo-Paris com mission protocol **Organization for Economic Co-Operation and Development
METHOD OF REMOVAL
When required, VpCI®-609/609 S in powder form can be easily removed by using a low pressure air gun or by a water rinse. Typically, if applied in aqueous form, the product does not require removal. If necessary, a simple water rinse or flush will suffice.
LIMITATIONS
• Do not use on copper, copper-based alloys, and other soft
yellow metals. Compatibility with non-metalics should be
evaluated.
• 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.
To avoid caking of powder do not over apply or unevenly
disperse the dry powder. In aqueous applications make
sure powder has been totally dissolved before using. Over
extended periods of protection, this caking may require
a more involved cleaning prodedure. Contact Cortec®
Technical Service for futher details.
• Powder is not soluble in hydrocarbon fluids. Rinse powder
from vessels before adding hydrocarbon fluid.
• Powder should be removed from the area on each side of
weld before welding, or other high temperature processing.
Note: Regular VpCI®-609 has a tendency to clump. For dry fogging application use VpCI®-609 S (with silica) where acceptable
