Zinc Anode 620 — Datasheet Overview

Key specifications

• Product name: Zinc Anode 620
• Material: High-purity zinc alloy (≥99.9% zinc typical)
• Form factor: Rod/strip (dimensions vary by manufacturer)
• Nominal weight: ~620 g (product code implies 620 g mass — confirm with supplier)
• Dimensions (typical): length 150–300 mm, diameter 20–40 mm (manufacturer-specific)
• Operating environment: Seawater, brackish water, freshwater, soil (sacrificial corrosion protection)
• Electrochemical potential: Approximately −1.05 V vs. SHE (standard for zinc in seawater)
• Current capacity (theoretical): ~820–860 Ah/kg (zinc theoretical: ~823 Ah/kg); for 620 g → ~510–530 Ah theoretical
• Design life estimate: Depends on impressed current, environment, and installation; calculate from consumption rate (mA/cm²) and mass
• Attachment method: Bolted or welded copper/stainless steel lug, cast-on terminal, or threaded stud
• Coating/finish: Uncoated (fresh zinc surface) or individually packaged to minimize oxidation
• Standards & approvals: ISO 15589-2 (shore and marine cathodic protection anodes), NACE recommendations (typical references) — verify per manufacturer
• Storage: Dry, cool conditions; avoid long exposure to humid air to reduce surface oxidation
• Typical applications: Ship hulls, offshore structures, pipelines, tanks, heat exchangers, marine fittings, cathodic protection test coupons

This is a two-pack, high-solids, epoxy zinc-rich primer designed to provide superior corrosion protection to steel in aggressive environments like offshore platforms and petrochemical plants. Key Features:

• Zinc (Zn): 99.9%
• Lead (Pb): Up to 0.3% (improves castability)
