VCI-300 Powder is a vapour-phase corrosion protection product designed for metal surfaces inside cavities, hollow sections, machinery housings and enclosed packaging. The VCI powder is packed inside a breathable non-woven bag. Once placed in a closed space, it releases corrosion-inhibiting vapour that travels around the component and forms a thin protective layer on exposed metal. VCI+ lists a basic usage rate of approximately 100–130 g/m³, an effective placement distance of less than 30 cm, and pack sizes ranging from 2.5 g to 500 g. The product is suitable for many metals, including steel, cast iron, copper, brass, aluminium, zinc, nickel and tin. VCI+ also states that VCI-300 contains no silicone, phosphate or heavy metals and meets RoHS requirements. Nassguard supplies VCI Corrosion Inhibitor Powder across Qatar and Doha for machinery protection, storage and export packaging.
More Details
VCI corrosion inhibitor powder metal parts often need protection long before they are installed. A gearbox may sit inside a crate for months. Spare components may remain in a maintenance store until the next shutdown. Electrical equipment can also contain metal surfaces that are difficult to coat by hand. VCI-300 Powder is made for situations like these.
The product uses VCI corrosion inhibitor powder packed inside a non-woven bag. Once placed inside a closed space, the active ingredients release protective vapour. That vapour moves through the enclosed area and settles on metal surfaces, forming a very thin protective layer that helps reduce contact with moisture and oxygen.
VCI-300 is especially useful for hollow sections, cavities, holes, curved surfaces and other internal areas where direct application of oil or coating may be difficult. VCI+ lists the product for metals such as steel, copper, aluminium, cast iron, brass, bronze, zinc, nickel, tin and several alloys.

What is VCI-300 Powder?
VCI-300 Powder is a vapour-phase corrosion protection product. VCI means Volatile Corrosion Inhibitor. Instead of relying only on direct contact with the metal, VCI molecules move through the air inside an enclosed package or cavity. After the powder begins releasing vapour, the inhibitor molecules travel around the internal space and adsorb onto exposed metal surfaces. This creates a microscopic barrier that reduces the ability of moisture and oxygen to start corrosion.
That is the main advantage of VCI-300. Imagine the inside of a machine housing, a hollow steel section or a component with deep holes. Applying oil evenly to every internal surface can take time, and some areas may still remain untreated. A VCI Anti Rust Powder can protect these harder-to-reach sections without requiring direct coating of every surface.
The powder itself is contained inside a breathable non-woven bag, which keeps the active material together while allowing the protective vapour to pass into the enclosed space.
Key Features of VCI-300 Powder

How Does VCI-300 Powder Work?
VCI-300 works best inside a closed or confined space. Place the powder bag within the recommended distance of the metal surface. VCI+ gives a general effective range of less than 30 cm. Because the protective vapour is denser than air, the manufacturer recommends placing or suspending the bag toward the upper part of the protected item where practical. After the enclosure is closed, the powder begins releasing vapour-phase inhibitor molecules. The manufacturer lists an induction period of around 30–40 minutes in a fully enclosed space. During this period, the VCI atmosphere develops around the metal.
The molecules then adsorb onto the metal and form a thin protective film. This is especially useful when dealing with hollow machinery, electronic equipment, cavities or irregular components where direct coating would be inconvenient. A basic usage rate of 100–130 g/m³ is listed by VCI+, although harsher environments may require more material.

Conclusion
Some metal surfaces are easy to protect. Others are hidden deep inside a housing, a bore or a machine cavity. That is where VCI-300 Powder becomes useful. Instead of coating every internal surface manually, the powder releases VCI molecules into the enclosed space. Those molecules move around the component and form a thin protective layer on the metal. The method works particularly well for machinery cavities, gearboxes, electronic equipment, hollow sections, machined parts, bearings, spare components and export packaging.
VCI+ also lists a broad range of compatible metals and states that the product contains no silicone, phosphate or heavy metals and meets RoHS requirements. For companies searching for VCI Anti Rust Powder, Corrosion Protection Powder, Metal Protection Powder, Rust Preventive Powder or VCI Powder for Metal, VCI-300 offers a practical way to protect internal and hard-to-reach metal surfaces.
