VCI Powder is specially designed to provide interior metal surfaces of enclosed systems with protection from corrosion damage. Often used as:

  • Lay-up, preservation and mothball applications to protect the internal cavities and recesses of equipment.
  • Preserving of equipment that requires hydrostatic testing before shipment and storage.
  • In a mothballed facility, the VCI powders keep machinery in working conditions so that production can quickly resume when needed.

Water-soluble and silica-free, the VCI powders are specially designed to protect the interior metal surfaces of enclosed systems such as:

  • Boilers
  • Turbines
  • Heat exchangers
  • Compressors
  • Tubes, pipes
  • Power generation equipment
  • Mining equipment
  • Drilling equipment

VCI powder can be applied by dusting, sprinkling or fogging it into an enclosed space with the use of a low-pressure air hose, or by dissolving it in water.

Om Mas’s VCI powders are not only safe and environmentally friendly, but they are also free from phosphates, heavy metals and nitrates.

Nox-Rust VCI Powder 1000SF

Nox-Rust VCI Powder 1000SF is designed to protect ferrous metals from corrosion causing elements. A silica-free and water-soluble powder, the 1000SF protects equipment during storage, lay-up and hydrostatic testing. Available in two different forms:

  • Nox-Rust 1000SF Loose Powder

Apply the powder by dusting, fogging or dissolving it in water. Removal of powder before restarting the unit after shut-down is not required. Sold in 5-lb & 25-lb boxes.

  • Nox-Rust 1000SF Pouch Emitter

Each 8″ x 11″ pouch contains Nox-Rust 1000SF powder, able to protect up to 900 cubic feet of enclosed space. Place the powder inside boilers, tanks, void spaces inside vessels, turbines and stream or condensate pipelines.

The breathable polyethylene sealed bag is then able to diffuse slowly, protecting ferrous metals during extended periods of equipment inactivity, during storage or lay-up.

Nox-Rust VCI Powder 1000SFG

A finely grounded version of the 1000SF, the 1000SFG features similar usage and purposes, protecting metals from corrosion. They are ideal for applications where a fine powder is needed.

Nox-Rust VCI Powder 1010SFG

Silica-free and water-soluble, the Nox-Rust VCI Powder 1010 SFG is a finely grounded powder, best suited for ferrous metals, including other metals such as copper, brass and galvanised steel. Applied when either wet or dry, it does not need to be removed before the restart/usage of equipment.

Nox-Rust VCI Powder 1015

Water-soluble & silica-free, the Nox-Rust VCI Powder 1015 protects ferrous metals in equipment during storage, lay-up and hydrostatic testing from corrosion and rusting.

Also available in:

  • Nox-Rust 1015 Pouch Emitter

The pouch emitter can protect up to 15 cubic feet of exposed metals inside an enclosure. Each pouch emitter eliminates the need to fog or spray powders when such application methods are not possible or not ideal.

Key Features


There are two ways to apply VCI Powder as a coating, wet or dry application.

For dry application, the anti-corrosion powder can be applied by dusting, fogging or sprinkling. The powder can later be removed by compressed air or water.

For wet application, mix with water and then apply the mixture by either spraying, brushing or dipping the equipment directly into it.

can be used in:

  • Tubular structures, pipes and vessels.
  • Internal surfaces of compressors, turbines, engines,tanks, boilers, heat exchangers.
  • Equipment protection after hydrostatic testing.
  • Parts, components and completed assemblies during
  • Shipping and storage.
