Corrosion remains one of the most critical challenges in industrial systems exposed to water — particularly in environments where oxygen presence accelerates degradation.
Rodanco’s CI 3090 is a high-performance film-forming corrosion inhibitor developed to provide durable protection for carbon steel and ferrous metals in both freshwater and seawater environments .
Engineered for Immediate and Long-Term Protection
CI 3090 works by forming a protective film on metal surfaces, effectively preventing corrosion from the moment of application.
This makes it particularly effective in:
- Preventing flash corrosion after cleaning
- Protecting systems exposed to water during operations
- Maintaining integrity during temporary or intermittent exposure
Unlike conventional solutions, CI 3090 retains effectiveness even after re-exposure to water, ensuring long-lasting protection in dynamic environments .
Designed for Real Industrial Applications
CI 3090 is widely used in:
Deluge Systems
Applied during system testing to protect internal piping, especially in cases of incidental activation.
Hydrotesting
Dosed into filtered and deaerated seawater to ensure immediate protection of internal surfaces during testing.
Pipeline & Equipment Preservation
Protects spool pieces, pipeline internals, and systems exposed to seawater ingress.
Recommended dosing:
- Hydrotesting: 100 – 500 ppm
- Deluge systems: 0.5 – 4% v/v dilution
Suitable for Offshore Environments
CI 3090 is registered with CEFAS (Gold category), making it suitable for offshore applications, including operations in environmentally sensitive regions such as the North Sea .
The product is also:
- Readily Biodegradable
- Water-dispersible
- Effective in oxygen-rich conditions
