nC Corrosion Passivator – Cold Alloy is a 2-component metal treatment that passivates both new and blasted metal. It stops and prevents the corrosion process and prevents galvanic corrosion.
It is applied by roller, brush, spray or ESS and adheres chemically via a sol-gel process with the metal, forming so-called electron pairs there. nC Corrosion Passivator Cold Alloy is resistant to welding and chemicals and remains active for up to 25 years.
Important product features
- Cancels electrical current of different
metals (galvanic corrosion). - Resistant to welding and fire.
