nC Corrosion Passivator Fluid
Developed for difficult‑to‑reach areas and confined spaces. With minimal surface preparation, both maintenance costs and downtime are reduced. After treatment, the metal surface changes to dark anthracite. The Fluid is free of VOCs, solvents and heavy metals, and can be applied using a brush, roller, spraying or floating.
Minimal Pre‑Treatment
High‑pressure washing (≥500 bar) is sufficient.
Single‑Layer Application
Suitable for brushing, rolling, spraying or floating.
VOC & Solvent‑Free
Free of VOCs, solvents and heavy metals.
What is nC Corrosion Passivator Fluid?
nC Corrosion Passivator Fluid is a solvent‑free, single‑layer coating designed to passivate corroded metal without blasting. It is ideal for enclosed or hard‑to‑reach areas such as ballast water tanks, peaks, cofferdams and pipelines.
After penetrating the rust layer, the Fluid bonds chemically to the metal surface, creating a durable, dark‑anthracite protective barrier. Only high‑pressure washing (≥500 bar) is required for surface preparation, and it can be applied directly onto dry or damp steel using a brush, roller, airless spray or by floating.
Typical Applications
- Ballast water tanks, peaks, double bottoms and cofferdams
- Cavities, wells and hollow structures such as pipelines
- Corroded surfaces where blasting or full coating systems are impractical
- Steel structures in marine, offshore and industrial settings requiring life extension
Suitable Environments
- Both dry and damp corroded surfaces
- Enclosed or hard‑to‑reach areas such as ballast tanks, cofferdams, peaks and pipelines
- Projects requiring minimal downtime and reduced surface preparation costs
- Long‑term protection in both freshwater and seawater
How It Works : Simple 4-Step Process
1
Surface Preparation
Remove standing water and mud. Remove loose rust flakes and coatings. High‑pressure cleaning (>500 bar, rotating) is recommended.
2
Application
Apply the Fluid by brush, roller, airless spray or floating onto dry or damp steel surfaces.
3
Passivation
The product penetrates the rust layer and chemically passivates active corrosion; treated surfaces change to a dark anthracite colour.
4
Durable Protection
A protective film is formed that provides long‑lasting corrosion protection. Avoid taking in ballast water for 48 hours after treatment.
Field‑Proven Results
Since 2005, nC Corrosion Passivator Fluid has been applied in professional shipping and industrial projects. It passivates severe corrosion in ballast tanks, peaks and structural steel without blasting. Field experiences show that it reduces maintenance time and surface preparation costs, while extending asset life and delaying costly steel replacement.
