The "620" typically denotes the net weight (0.62 kg or 1.37 lbs) of zinc, though some industrial suppliers use the code for a 620 cu. cm volume. The most common commercial variant used in North America and Europe is the Hull Mount 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.
Standard Dimensions (Typical for 620 Profile):
Note: Always verify manufacturer drawings, as "620" may refer to length in millimeters for custom extrusions.

The Zincanode 620 is a high-solids, two-pack epoxy zinc-rich primer designed for superior corrosion protection of steel in aggressive environments. It acts as a sacrificial layer, providing "galvanic protection" to the steel substrate. Product Overview
Primary Use: Anti-corrosive primer for marine and port facilities, offshore structures, petrochemical plants, and piping.
Compliance: Meets British Standard BS 4652 for zinc-rich primers and ISO 12944 Part 2 for environments up to C5.
Key Feature: Contains over 80% zinc by weight in the dry film to ensure long-term cathodic protection.

Surface Prep: Requires abrasive blast cleaning to a minimum standard of Sa 2½ (ISO 8501-1) with a surface profile of 50–75 microns. Drying Times (at 25°C): Touch Dry: 20 minutes. Hard Dry: 6 hours. Overcoating Interval: Minimum 12 hours. Pot Life: 8 hours. Restrictions & Safety
Environment: Not recommended for immersion in acidic or alkaline conditions without a suitable topcoat.
Weathering: Like most epoxies, it will chalk and discolor if exposed to direct sunlight without a topcoat.
Safety: Ensure adequate ventilation and wear protective gear (goggles, gloves). The product is flammable with a flash point of 20°C. Zincanode 620 | Epoxy Zinc Rich Primer

Scenario (6.8 kg hull anode):
If you are searching for "Zinc Anode 620 datasheet," you likely need zinc specifically. Here is the reality check:
| Property | Zinc Anode 620 | Aluminum Anode (Al/Zn/In) | Magnesium Anode | |------------------------|------------------------|----------------------------|-----------------------| | Capacity (A·hr/kg) | 780 | 2,500 | 1,200 | | Driving Voltage | 0.25V (Low) | 0.30V (Moderate) | 0.70V (High) | | Best For | Seawater, Warm water | Seawater, Mud (Cost effective) | Soil, Fresh water | | Weight for 620 size| 6.2 kg | 2.4 kg (Same volume) | 1.8 kg (Same volume) |
Conclusion for the 620: Choose zinc ONLY for saltwater/brackish water. Do not use zinc in low-temperature fresh water or in high-sulfide muds.
