Zinc Anode 620 Datasheet [portable]

Zincanode 620 is designed for steelwork in highly corrosive "C5" environments, including: Marine & Offshore

-1.05 Volts relative to a Silver/Silver Chloride (Ag/AgCl) reference electrode. Closed Circuit Potential: -1.03 Volts vs. Ag/AgCl.

Ensure the mounting studs are wire-brushed and clean before bolting. Replacement Schedule

Operators must use appropriate protective equipment, including air-fed hoods, protective clothing, and solvent-resistant gloves. zinc anode 620 datasheet

-1.05 V vs. Ag/AgCl reference electrode.

To meet (the gold standard for zinc anodes), the alloy must adhere to these strict percentages: Zinc (Zn): Remainder (approx. 99.3%) Aluminum (Al): 0.10% – 0.50% Cadmium (Cd): 0.025% – 0.07% Iron (Fe): 0.005% Max Lead (Pb): 0.006% Max Copper (Cu): 0.005% Max ⚡ Performance Characteristics

Meets the rigorous standards of BS 4652 and conforms to the performance requirements of BS 5493. 3. Technical Specifications Understanding the physical and chemical properties of Zincanode 620 Zincanode 620 is designed for steelwork in highly

: Supplied with a standard lead wire (e.g., 10ft of #12 AWG THHN/THWN) for connection to the structure. 🌊 Primary Applications

Cathodic protection is the frontline defense against galvanic corrosion in marine and industrial environments. Among the various sacrificial anodes available, the represents an industry standard for mid-sized vessels, commercial hulls, and heat exchangers.

Note: As this is a zinc-rich epoxy, it may chalk or discolor when exposed to sunlight, which is typical for this type of coating .

: Best applied via airless spray (Tip size: 0.43–0.53 mm). Brushes or rollers are generally reserved for touch-ups or small areas. Drying Times (at 25°C) : Touch Dry : 20 minutes. Hard Dry : 6 hours. Pot Life : 8 hours. Sacrificial Anode Alternative: Model 620

>95% (No hydrogen embrittlement risk for high-strength steel).

Choosing the correct one depends entirely on your application: use the coating for structural steel protection and the sacrificial block for your boat's underwater metals. Always consult the official product datasheet for precise installation instructions and confirm specifications meet ASTM or MIL-STD requirements for reliable performance.

To ensure reliable performance, high-quality 620 zinc anodes are cast to meet strict international standards, most notably (US Military Specification) or ASTM B418 Type I . These specifications guarantee that the anode will not "passivate" (form an insulating crust) in saltwater.
