VpCI 425 is a remarkable powder specifically designed to tackle light oxides and staining on copper, steel, and aluminium surfaces.

When mixed with water at a concentration of 5-12% by weight, this powerful yet safe solution becomes a go-to choice for cleaning various chemical manufacturing equipment such as blenders, reactors, cooling towers, heat exchangers, and water pipes.


Enhanced with an array of exceptional features, VpCI® 425 proves to be a remarkable solution for tackling rust and scale issues. This product not only eliminates rust and scale efficiently but also lays the groundwork for protective coatings, ensuring comprehensive corrosion protection.

Reduced Waste Treatment
One of the standout features of VpCI® 425 is its ability to significantly reduce waste treatment requirements, streamlining the maintenance process and minimising environmental impact.

Moreover, the environmentally-friendly nature of VpCI 425 further enhances its appeal. It is non-toxic, biodegradable, and safe to handle, making it a suitable choice for companies striving to meet sustainability goals and reduce their environmental impact.

Neutral pH

Moreover, VpCI® 425 boasts a neutral pH, which not only contributes to prolonging the lifespan of equipment but also enhances safety during handling, usage, and storage. Its innovative powder form not only facilitates easy handling but also translates to substantial savings on shipping costs. Emphasising quality and performance, VpCI® 425 is comprised of 100% active material, entirely free from fillers, guaranteeing maximum effectiveness and value.

Water Soluble

With its water-mixable nature, VpCI® 425 effortlessly integrates with water-based solutions, simplifying the application process and ensuring seamless compatibility. Whether applied in industrial settings, manufacturing facilities, or other corrosive-prone environments, VpCI® 425 stands as an exceptional choice, showcasing an unparalleled combination of rust removal, protective coating readiness, and environmentally-conscious attributes.

Wide Range of Applications

VpCI 425 is particularly effective for protecting various metal components against corrosion during storage, transportation, or operating processes. Its unique vapor phase corrosion inhibitors create a protective layer on metal surfaces, preventing the formation of rust and corrosion, even in challenging environments.

The application of VpCI 425 extends to a wide range of industries, such as manufacturing, marine, automotive, and aerospace. It can be utilised for protecting critical components, machinery, equipment, and infrastructure, ensuring their longevity and reducing maintenance costs.

One of the key advantages of VpCI 425 is its ability to provide long-lasting protection for both ferrous and non-ferrous metals, including steel, aluminium, copper, and more. This versatility makes it a preferred choice in various industrial settings where different metal types coexist.


To apply VpCI® 425 effectively, begin by mixing the product with water until the desired concentration is achieved, ensuring not to exceed the maximum solubility of 12-14% by weight. The solution's performance is optimised when parts are fully immersed (dipped or flooded) in the VpCI 425 solution. For enhanced results, it is recommended to maintain the solution's temperature between 140°F to 200°F (60°C to 90°C) through heating.

For optimal corrosion protection, allow the parts to remain in contact with the VpCI-425 solution until the desired outcome is achieved. The duration of immersion may vary from one part to another, depending on several factors, including the severity of corrosion, the temperature of the solution, the substrate material, and other relevant considerations. Cleaning times can range from just a few minutes to several hours, depending on the specific conditions.

Packaging and Storage

VpCI 425 comes in various packaging options. You can choose from 5-pound, 50-pound, and 100-pound fiber drums, as well as bulk containers. To ensure its effectiveness, it is essential to store VpCI 425 in a dry warehouse, away from direct sunlight, and at temperatures below 122°F (50°C). You can safely store VpCI 425 under these conditions for around 36 months.
