The surface remains greasy for several months.
Avoid contact with chemicals or soaps.
Do not take in ballast water during the first 48 hours.
Paintable
No
Lifetime
Long-lasting corrosion protection in both freshwater and seawater.
Storage
5 – 35°C (store out of direct sunlight).
Up to 5 years in the original container.
Reaches inaccessible spaces
100% coverage can be achieved with nC Corrosion Passivator Fluid in ballast tanks, peaks, double bottoms or other confined spaces. because Fluid can be applied by brush, roller, spraying or floating.
No blasting required
Corrosion Passivator Fluid is developed to prevent corrosion without the need for blasting, this solution requires minimal pre-treatment. High-pressure wash (500 bar) is sufficient, saving time, reducing costs, and minimizing waste.

Frequently asked questions ⇢
Store Corrosion Passivator Primer 2-in-1 between 0°C and 35°C. Storage for up to 2 years in a tightly closed, original container at temperatures below 35°C.
More information can be found on the product page.
nC Corrosion Passivator Primer 2-in-1 provides long-lasting protection when properly overpainted.
More information can be found on the product page.
Yes, nC Corrosion Passivator Primer 2-in-1 is a direct-to-rust solution and should be painted over for the best results (after 4 to 6 hours at 20°C). Corrosion Passivator 2-in-1 stabilizes the surface by converting rust into pores and binding it to the metal. This provides long-lasting protection and better adhesion of the next layer of coating due to extra roughness of the surface.
More information can be found on the product page.
This depends on usage. Over time, the greasy surface will disappear after usage.
More information can be found on the product page.
If rusty spots are discovered during inspection after application, simply touch up these spots using a brush, roller, or spray.
More information can be found on the product page.
After treatment with the Fluid, the metal surface changes from rust-colored to anthracite/dark purple. This color change indicates that the surface has been treated and protected by the Fluid.
More information can be found on the product page.
nC Corrosion Passivator Fluid reacts quickly with the metal surface. The liquid has an oily/greasy base, so the tanks will remain greasy for at least several months, depending on usage. To maintain effectiveness, avoid contact with chemicals or soaps and refrain from taking in ballast water for the first 48 hours. More information can be found on the product page.
The tank can be pumped out at a maximum rate of 20 cm per minute. Make sure that the last segment of water with residue is properly discharged according to local regulations. For ships, residue can be discharged to the wastewater tank.
More information can be found on the product page.
To ensure optimal adhesion of the Corrosion Passivator Fluid to the metal surface, it is important that the water filling rate does not exceed 20 cm per minute. Slowly filling the tank is preferred to ensure that the passivator remains floating on the water.
More information can be found on the product page.
Both freshwater and saltwater can be used when floating the tank with nC Corrosion Passivator Fluid. If both options are available, it is advisable to opt for fresh water, as it creates a less aggressive environment for corrosion.
More information can be found on the product page.
The Fluid should be evenly distributed between the webframes on the bottom of the tanks, peaks, or double bottoms for optimal distribution.
More information can be found on the product page.
When working in confined spaces, it is important to ventilate the areas well. Use appropriate equipment to monitor air quality. If using spraying equipment, ensure proper ventilation with over pressure.
More information can be found on the product page.
What personal protective equipment is required for the application of nC Corrosion Passivator Fluid?
Required personal protective equipment can be found in the Product Data Sheet (PDS).
More information can be found on the product page.
For floating application, the water temperature ideally ranges between 10°C and 30°C. When the Corrosion Passivator Fluid is sprayed, the ideal temperature is between 15°C and 30°C.
For brushing or rolling the product, the temperature should be between 10 and 35 °C.
More information can be found on the product page.
Do not add thinner. The product is ready to use and only needs to be stirred well before use, to ensure that all components are thoroughly mixed.
More information can be found on the product page.
The recommended application method is floating or spraying/rolling. The consumption rate is 1 liter per cubic meter when the floating method is used. When sprayed, 5m2 of rusty surface can be treated per liter.
More information can be found on the product page.
No, the Corrosion Passivator Fluid can be applied to both dry and damp surfaces.
More information can be found on the product page.
Do I need to completely remove all rust and paint before applying the nC Corrosion Passivator Fluid?
No, sanding, blasting or sanding is not necessary. It is sufficient to remove mud and loose rust and/or paint. Since the Corrosion Passivator Fluid is applied directly over rust, it is not necessary to completely remove all rust and paint. Surfaces with well-adhering coatings remain unaffected.
More information can be found on the product page.
Remove loose rust, loose coating and mud from the surface. Drying with heaters is not required. The steel can be dry or damp before treatment with nC Corrosion Passivator Fluid.
More information can be found on the product page.

It should be stored between 0°C and 50°C, for up to 15 years in the well-sealed original container.
More information can be found on the product page.
In fresh water, it provides up to 15 years of rust protection, while in saltwater, it remains active for up to 8 years, as indicated by customer experiences. After treatment, the steel undergoes a color change to dark purple, almost black.
More information can be found on the product page.
It is not possible to paint over nC Corrosion Passivator Fluid and also not necessary, since it’s a single-layer solution. The substrate remains greasy. Over time, the oil will penetrate or evaporate from the steel.
More information can be found on the product page.
When nC Corrosion Passivator Fluid is applied by floating, the consumption rate is 1 liter per cubic meter. When applied by spraying, rolling or brushing, 1 liter is needed for every 5 square meters of surface area.
