Zinc Anode 620 Datasheet May 2026

Zincanode 620 is a high-performance, two-pack epoxy zinc-rich primer specifically engineered for superior corrosion protection of steel in aggressive environments. It functions as a sacrificial primer, providing galvanic protection even if the coating film is damaged. Core Technical Specifications

9. Troubleshooting Premature Failure

Symptom: The 620 anode is hard, white, and "crusty" while the steel is corroding. Diagnosis: Passivation. Cause:

Seawater applications: Offshore platforms, pipelines, and coastal structures.
Brackish water applications: River estuaries, tidal zones, and freshwater/saltwater mixing areas.
Soil applications: Buried pipelines, storage tanks, and other underground structures.

The Zinc Anode 620 is made from high-purity zinc, with a minimum purity of 99.5%. The anode's composition is as follows: zinc anode 620 datasheet

I couldn’t find an official or universal datasheet for a "Zinc Anode 620" because that part number isn't a standard industry designation across major marine or cathodic protection brands (e.g., Martyr, Cambrian, MG Duff, Galvotec).

In conclusion, zinc anodes play a vital role in cathodic protection systems, and the Zinc Anode 620 is a high-performance anode designed for use in various industries. The datasheet provides detailed information on the anode's composition, physical properties, and performance characteristics. By understanding the benefits and applications of zinc anodes, industries can ensure the effective protection of their metal structures from corrosion. The Zinc Anode 620 is made from high-purity

Brackish Water: Good (Aluminum may be preferred for low-salinity).

1. What is the "Zinc Anode 620"?

The term "620" typically denotes a Hull or Brace Anode weighing approximately 6.2 kg (13.66 lbs) or measuring roughly 620 mm in length depending on the manufacturer's code. However, the industry standard for the “620” profile most commonly refers to a trapezoidal or rectangular bar anode used predominantly on ship hulls, heat exchangers, and water box applications.
