nC Corrosion Passivator – Primer Zinc C5 is a metal treatment liquid. It forms an active galvanic anti-corrosion layer in the metal.
The metallic zinc powder acts as a sacrificial anode. Corrosive influences slowly transform the layer into an impermeable zinc oxide layer that remains effective even if the paint is scratched.
The combination of high purity binder and zinc ensures high mechanical resilience of the paint film while providing lasting active corrosion protection when the paint surface is damaged. Can be painted over. Protects up to 10 years in saltwater environments.
