Nox-Rust® VCI Powders
Nox-Rust® VCI Powders are engineered to provide continuous corrosion protection for the interior metal surfaces of enclosed systems. Use it:
-
- For long-term decommissioning, preservation, and storage applications to protect internal cavities and recesses.
- For preserving equipment and piping networks that must undergo hydrostatic testing prior to transit or storage.
- Maintained within mothballed facilities to keep internal machinery components functional, allowing production to be restored efficiently when required.
This water-soluble, silica-free VCI powder line is specialised to protect the interior metal surfaces of enclosed industrial systems, including:
- Boilers

- Turbines
- Heat exchangers
- Compressors
- Tubes, pipes
- Power generation equipment
- Mining equipment
- Drilling equipment
Apply VCI powders by manual dusting or sprinkling, fogging into the enclosed volume using a low-pressure air hose, or via direct dissolution in liquid water. The formulation does not contain phosphates, heavy metals, or nitrites, aligning with modern occupational health profiles.

Nox-Rust VCI Powder 1000SF
Metals Protected: Ferrous
Silica-free, water-soluble powder for protecting equipment during storage, decommissioning, or hydrostatic testing.
Nox-Rust 1000SF Loose Powder
Applied via dusting, fogging, or liquid dissolution. Due to its clean chemistry, removal is typically not required prior to equipment restart following a shutdown. Supplied standard in 5-lb (approx. 2.26 kg) and 25-lb (approx. 11.34 kg) containers.
Nox-Rust 1000SF Pouch Emitter 
Each 8” x 11” breathable polyethylene pouch contains 1000SF powder formulated to protect up to 900 cubic feet ($900\text{ ft}^3$ / approx. $25.5\text{ m}^3$) of enclosed space. Designed for placement inside boilers, tanks, structural void spaces, turbines, and steam or condensate pipelines. The breathable matrix diffuses slowly to protect ferrous components during extended periods of inactivity.
Nox-Rust VCI Powder 1000SFG
Metals Protected: Ferrous
A finely ground modification of 1000SF engineered specifically for industrial processes requiring an ultra-fine particle distribution.
Nox-Rust VCI Powder 1010SFG
Metals Protected:Multi-metal (compatible with copper, brass, and galvanised steel).
Silica-free, water-soluble, finely ground powder suitable for wet or dry application methodologies. Does not require removal or flushing prior to system restart.
Nox-Rust VCI Powder 1015
Metals Protected: Ferrous
Silica-free, water-soluble powder variant for storage, transit preservation, and hydrostatic environments.
Nox-Rust 1015 Pouch Emitter

Each Nox-Rust 1015 Pouch Emitter is calibrated to protect exposed metals inside an enclosure of up to 15 cubic feet ( 15 ft3 / approx. 0.42 m3 ). This delivery system eliminates the requirement to fog or spray loose powders when open dusting is impractical or restricted.
