Corrosion passivation

Corrosion Passivation in short

Corrosion passivation means that you stop the corrosion process without the absolute need for sandblasting or traditional coating. This makes the execution of corrosion passivation projects fast and cost effective, whilst the results last for very long periods of time. A chelate technique lasts 5 years and longer in saltwater environments (nC® Nano Corrosion Passivator Fluid), or go over 15 years of no corrosion when nC® Nano Corrosion Passivation Cold Alloy Paint is the product of choice.

Corrosion passivation fluid works through the chelation process. Here, particles form a bond with the iron behind the rust (if present). It pulls specifically the loose iron oxide apart from the surface. These nano particles form a flexible barrier on and inside the capillar and intermolecular structure of the metal surface. The formulation passivates the metal corrosion process.

The corrosion passivating cold alloy paint has a sol-gel base formula. Suitable for either new or blasted metal, or metal with already present (heavy) corrosion. The particles bond chemically with the metal surface. It adds a cold alloy that can only be removed through rupture. nC® Nano Corrosion Passivator Paint withstands welding temperatures.

If you have material thickness that is sufficient now, but will expectedly be subject to replacement during the next special or intermediate survey, nC® Nano Corrosion Passivator is your solution to keep thickness as it is right now.

Application benefit

Particularly, a big advantage of corrosion passivation is that you can apply it on wet surfaces. Consequently, it is also possible to passivate corrosion in for example ballast water tanks, rudders, peaks and other confined areas by means of floating. Of course traditional application, like rolling, brushing or spraying, is possible, on wet surfaces.
