VCI 2000 POWDERS
Product Description
VCI POWDERS are Vapor Corrosion Inhibitor (VCI) powders for corrosion protection of metals in recessed areas, interior cavities and voids.
Features
Does not contain Silicones, Nitrites or heavy metals.
Protects up to 1.0 cubic foot (28 liters) per 0.3 ounces (8.4 grams) of powder. (300g/cubic meter) Provides up to 24 months of continuous protection.
Provides mono-molecular inhibiting layer.
VCI powders provide an extremely efficient dry method to protect metals within anenclosed space. The VCI vaporizes and then adsorbs on all metal surfaces, reaching every part of the metal surface, including recessed areas and interior cavities.
Benefits
Vapor-phase inhibiting action protects inaccessible and recessed surfaces.
Protected products can be shipped to customers without removing powder.
No regeneration required; effective for up to 24 months.
If VCI layer is disturbed by moisture or opening the enclosed space, the layer is replenished by continuous vapor protection.
Little or no surface preparation required.
Prevents further corrosion of the pre-coated and painted surfaces.
Easy to apply.
VCI layer does not need to be removed prior to processing or use.
Very easily removed by air gun or water when applied as a powder.
VCI layer does not interfere with operation of mechani-cal components.
Application
VCI powders are used for dry protection of internal cavities and voids that can be covered or closed after application.
Tubular structures, pipes and vessels.
Internal surfaces of compressors, turbines, engines,
tanks, boilers, heat exchangers.
Dry lay-up of closed circuit cooling systems.
Equipment protection after hydrostatic testing.
Parts, components and completed assemblies during
shipping and storage.
Method of Application
Apply powder by dusting, fogging or sprinkling. After application, simply cover, close or seal 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.
For powder application with average environmental conditions,
use 0.3 ounces (8.4 grams) of VCI-POWDER per one cubic foot (28 liters) of enclosed space(300grams/cubic meter). The dosage can be increased for more severe conditions.
Method of Removal
VCI powder can be easily removed by using a low
pressure air gun or by a water rinse.
Metals Protected
Carbon steels, Stainless steels,
Exposure Limitations
For use in interior cavities and voids that are covered, closed or sealed after application.
Product can be stored indoors or out-doors.
