VCI Powder is a one-of-a-kind water-soluble chemical compound that is used to control the corrosion of aluminum and ferrous metals. It has a white crystalline appearance and is an excellent choice for dry fogging, hydro testing, or as an additive to various water-based solutions such as metal washing compounds, final rinsing solutions in the manufacturing line, and test baths. It effectively prevents metal corrosion and rusting caused by adverse environmental conditions such as seawater, high humidity or moisture, or harsh environments. The VCI Powder can be applied in either a dry or wet manner. It provides a simple and quick application and does not require any processing to be used. When necessary, an air gun or water can be used to easily remove it. The powder layer has no effect on the operation of mechanical metal components.
VCI Powders are designed to provide interior metal surfaces of enclosed systems with protection from corrosion causing elements. The common application uses of these powder include:
Water-soluble and silica-free, the VCI Powder is capable of protecting the interior metal surfaces of enclosed systems such as:
The Nox-Rust® VCI Powder is applied by dusting, sprinkling or fogging it into an enclosed space with the use of a low-pressure hose or by dissolving it in water. Stream Peak’s VCI Powders are not only safe and environmentally friendly, but they are also phosphate, heavy metal and nitrate-free.
The Nox-Rust VCI Powder 1000SF protects ferrous metals from corrosion and rusting. Silica-free and water-soluble, the 1000SF protects equipment during lay-up, storage and hydrostatic testing. It is also available in two different forms:
The 1000SF loose powder can be applied by dusting, fogging or dissolving it in water. Removal of the powder is not needed when restarting the equipment. It is sold in 5-lb & 25-lb boxes.
Each Nox-Rust 1000SF Pouch Emitter comes in 8″ x 11″, capable of protecting up to 900 cubic feet of enclosed space. Use the pouch emitter by placing it inside boilers, tanks, void spaces inside vessels, turbines and stream or condensate pipelines. Once applied, the breathable polyethylene sealed bag is then able to diffuse slowly, protecting ferrous metals during equipment inactivity, storage or lay-up over a long duration.
The 1000SFG is a finely grounded version of the 1000SF, featuring similar functions. However, unlike the 1000SF, the 1000SFG is ideal for applications where a fine powder is needed.
Silica-free and water-soluble, the Nox-Rust VCI Powder 1010 SFG is a finely grounded powder, ideal for ferrous metals. It is also compatible with other metals such as copper, brass and galvanised steel. It can be used wet or dry. The powder does not require any removal before the restart/usage of the protected equipment.
Water-soluble & silica-free, the Nox-Rust VCI Powder 1015 protects ferrous metals in equipment during lay-up, storage, and hydrostatic testing from elements that result in corrosion. Other than powder form, 1015 is also available in:
The pouch emitter is capable of protecting up to 15 cubic feet of exposed metals inside an enclosure. These pouches are ideal where application methods such as fogging or spraying of powders are not ideal or possible.
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. The VCI Powder can be used in:
