nC Corrosion Passivator – Cold Alloy is a 2-component metal treatment that passivates both new and blasted metal. The product achieves a protection level comparable to industrial galvanisation, Without the use of heat and acid and with minimum layer thickness of ±30µm
It is applied by roller, brush, spray or ESS and adheres chemically via a sol-gel process with the metal. nC Corrosion Passivator Cold Alloy is resistant to welding and chemicals and remains active for up to 25 years.
