Used on steel sheet piles, jetty structures, and harbor lock gates.
75 microns (Dry) / 120 microns (Wet).
Zinc anodes require high-chloride environments to operate efficiently without passivating.
Contains more than 80% zinc by weight in the dry film, ensuring high electrical conductivity for galvanic protection. zinc anode 620 datasheet

The Zinc Anode 620 is a high-performance zinc anode designed for use in seawater, brackish water, and soil environments. It is commonly used for the cathodic protection of:
Designed for operating temperatures under 50°C (122°F). At temperatures exceeding 60°C (140°F), zinc undergoes a potential reversal, becoming cathodic to steel, which accelerates the destruction of the steel structure. Typical Use Cases Ship hulls and thruster tunnels. Ballast tanks and sea chests. Offshore drilling platforms and jackets. Harbor piers, pilings, and lock gates. 5. Installation and Maintenance Best Practices Used on steel sheet piles, jetty structures, and
Typically -1.05V to -1.10V (relative to a Ag/AgCl reference electrode in seawater). Closed Circuit Potential: Typically -1.00V to -1.05V.
: Recommended for airless spray, though brush or roller may be used for touch-ups or complex shapes.
Zinc anodes are the frontline defense against galvanic corrosion in marine and industrial environments. Among the various standardized sizes, the (often designated as a hull, rudder, or boiler anode depending on the manufacturer) is a widely utilized specification. Contains more than 80% zinc by weight in

A refers to a high-quality, sacrificial zinc anode manufactured to meet strict industry standards (often corresponding to ASTM B418 Types I or II or military specifications). These anodes are designed to protect steel structures, hulls, tanks, and pipelines from corrosion by corroding themselves, thereby taking the brunt of the environmental damage. Type: Galvanic (Sacrificial) Anode Material: High Purity Zinc (>99.99% Zinc) Primary Application: Marine and Underground Structures Technical Specifications (Datasheet Summary)
Replace the Zinc Anode 620 once it has consumed . Beyond this point, the surface area decreases rapidly, dropping the protective current output below safe thresholds. 6. Ordering Reference & Ordering Information
