Zerion® FVS’s two forms of protection:
1. Vapor Corrosion Inhibitors (VCIs) to protect the interiors of “air space” voids and exposed metal surfaces on welded joints, in crevices, at coating holidays, etc.
2. Soluble Corrosion Inhibitors (SCIs) that mitigate corrosion from moisture accumulation or the ingress of water.
This combination penetrates gaps and interstices inside of enclosed voids to provide comprehensive coverage.
The ready-to-use mesh sleeves are primarily meant for dry VCI application where there is also a risk of water ingress. The vapor space protection volume is provided in the table below. For aggressive environments with 1 ppm or higher level of acidic gases, Zerion® FVS should be used in combination with Zerion® AutoFog®. In the event of water ingress/ accumulation, FVS will dissolve out of the packaging and neutralize the threat up to the volume of water indicated in the usage table.
FVS does not contain phosphates and is readily compatible with most industrial water treatment processes.
Zerust® Zerion® FVS ready-to-use mesh sleeves typically provide 1-2 years of corrosion protection depending on how well the enclosure is sealed.
FVS mesh sleeves used in tank chime ring seals typically provide 4 years of corrosion protection depending on the integrity of the chime seal. Longer protection is possible with replenishment of the inhibitor.
When FVS is introduced into a tank SSB environment, either mixed in as a powder in the sand/soil or injected as concentrated slurry, the typical duration of protection is 5-10 years before inhibitor replenishment is required. The replenishment can be tied into periodic monitoring and maintenance of the effectiveness of the solution.
Shelf life is 36 months.
Store in a sealed container in a dry, ventilated warehouse at temperatures below 40°C.
