Active Cathodic Protection Coating for Marine Atmospheric and Immersed Steel | Zingametall

Active and Passive action as an alternative to hot-dip galvanising for long-term structural steel protection

ZINGA is a zinc rich film galvanising system used when steel is exposed to aggressive marine conditions offering continued protection in instances when the coating is scratched or locally damaged. Once an electrolyte is present, the zinc acts as the sacrificial anode and provides cathodic protection to the steel, while the binder and zinc oxide layer provide a barrier effect that helps prevent corrosion creep. In immersed service it is often treated as a liquid anode, and it can also be used as a primer in duplex systems where the topcoat adds additional barrier durability.

Zinga, liquid galvanising system offers the benefits of hot-dip galvanisation with the flexibility of an applied coating to protect these critical assets though a unique combination of active cathodic and passive barrier protection ensuring long term structural integrity.

Key Advantages: 

Dual Protection: Zinc particles provide sacrificial (cathodic) protection while the organic binder forms a continuous, impermeable barrier.

Surface Rechargeability: Can be overcoated on existing hot-dip galvanised or metallised surfaces, extending their service life.

Self-Healing Zinc Layer: Minor mechanical damage is self–replenished as exposed zinc particles sacrificially corrode to protect the steel.

C5 High-Corrosivity Rating: Tested to ISO 12944-6 C5 standards for offshore and marine exposure.
