Zinc Anode 620 Datasheet

Suitable for ISO 12944 C5 environments (highly corrosive). Temperature Resistance: Withstands dry heat up to Technical Specifications: Volume Solids: Dry Film Thickness (DFT): Typical 75 microns. Theoretical Coverage: Approximately at 75 microns DFT. Mixing Ratio: 3 parts Base to 1 part Hardener by volume.

To perform effectively as a sacrificial material, zinc must meet strict metallurgical standards. Most industrial 620 anodes are manufactured to conform to (Military Specification) or ASTM B418 Type I standards for marine environments.

The core contains pre-drilled holes. It is secured using backing washers, nuts, and bolts. This allows for rapid replacement during dry-dock servicing. Critical Considerations

Ø 110 mm Weight: Approximately 1.4 kg (3.1 lbs) for the zinc version Material: Zinc (an aluminum version is also available) Suitable for ISO 12944 C5 environments (highly corrosive)

Submerged protection against brackish or salt ballast water.

High-purity zinc (>99.99%) ensures that the anode does not "passivate" (form a hard crust that stops current flow). Mixing Ratio: 3 parts Base to 1 part Hardener by volume

To keep your hulls, tanks, and pipelines from dissolving, you need a sacrificial lamb—or in this case, a sacrificial metal. The

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
