Product description

      VCI is a Vapor Corrosion Inhibitor for corrosion protection of ferrous metals in recessed areas, interior cavities and voids.

  VCI provides an extremely efficient dry method  to protect metals within an enclosed space. The VCI  vaporizes and adsorbs on all metal surfaces reaching all exposed areas including recessed sections

and interior   cavities.                     

VCI, a silica-free version, is available upon request.


• Does not contain silicates, phosphates, nitrites, or heavy  Metals

• Provides up to 24 months of continuous protection

• Provides monomolecular inhibiting layer

• Vapor phase inhibiting action protects inaccessible and recessed surfaces

• Protected products can be shipped to customers without removing powder

• If the VCI layer is disturbed by moisture or opening the

enclosed space, the layer is replenished by continuous vapor redeposition

• Little or no surface preparation is required

• Prevents further corrosion of pre-coated and painted Surfaces

                 • Easy to apply

                 • When required powder can be removed by air gun or

                    water rinse

                 • Provides protection to ferrous metals only

                  • Conforms to MIL I-22110C

                  • LD50 ORAL: 2100mg/kg of body weight


                •Tubular structures, pipes, vessels, and turbines

                • Internal surfaces of compressors, turbines, engines,

                tanks, boilers, and heat exchangers

                • Dry lay-up of closed circuit cooling systems

                • Equipment protection after hydrostatic testing

                • Parts, components, and completed assemblies during

               shipping and storage

               • Segmental concrete bridge tendons/cables

              Method oF APPLicAtion

              Apply powder by dusting, fogging, or sprinkling. After

              application simply cover, close or seal the interior cavity or


              Fogging is easily achieved with a low pressure air hose

              and sandblast cup or by inverting a wet/dry vaccuum.

              Large conventional sandblasting systems can also be



             0.3-0.5 oz/ft3(300-500 g/m)



              When required, VCI in powder form can be

              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

           Appearance                            White to off-white

           Ph                                             6.5-8 (1% aqueous)

           Density                                      38-39 lb/ft(0.61-0.63 kg/L)



         • Caking of powder may occur when it is exposed to

           moisture and then dried. The likelihood of this is in-

           creased when powder is exposed to high heat and multi-

           ple wet/dry cycles. When powder gets caked, baked, and

           hardened it requires removal by mechanical means or by

           aggressive acid clean. To avoid caking of powder do not

           over apply or unevenly disperse the dry powder.

          • Powder is not soluble in hydrocarbon fluids. Rinse pow-

            der from vessels before adding hydrocarbon fluids.

         • Powder should be removed from area; 5-10 inches

           each side of weld, before welding, or other high

           temperature processing.
