Zincanode 620 is a high-performance, two-pack epoxy zinc-rich primer specifically engineered to provide superior cathodic and barrier protection for steel in aggressive environments. www.bergerarabiapc.com Technical Specifications The following data reflects the standard Berger Zincanode 620 Technical Data Sheet Zinc Content
: Contains over 80% zinc by weight in the dry film to ensure effective galvanic protection. Volume Solids : Approximately Dry Film Thickness (DFT)
: Typically 75 microns (can range between 50 and 75 microns). Wet Film Thickness (WFT) : 120 microns. Theoretical Coverage /liter at 75 microns DFT. Finish & Color : Matt finish in Metallic Grey. Heat Resistance : Resists dry heat up to 150°C. www.bergerarabiapc.com Key Applications
Zincanode 620 is designed for steelwork in highly corrosive "C5" environments, including: Marine & Offshore
: Ship superstructures, offshore platforms, jetties, and port facilities. Industrial Infrastructure : Pipelines, bridges, and petrochemical plants. Maintenance
: Often used as a repair coating for inorganic zinc-rich primers. www.bergerarabiapc.com Application Details Mixing Ratio : 3 parts Base to 1 part Hardener (by volume). Drying Times (at 25°C) : 20 minutes. : 6 hours. : 8 hours. Surface Preparation
: Requires abrasive blast cleaning to a minimum standard of Sa 2½ (ISO 8501-1:1988) for optimal adhesion. Application Method
: Airless spray is recommended, though brushes or rollers may be used for touch-ups or complex shapes. www.bergerarabiapc.com Limitations
: Not recommended for immersion in acidic or alkaline conditions unless a suitable topcoat is applied. UV Exposure
: Like most epoxy products, it may chalk or discolor when exposed to direct sunlight. www.bergerarabiapc.com comparison between Zincanode 620 and other zinc-rich primers like the zincanode 620 - Berger Protective Coating [UAE]

Introduction
The Zinc Anode Type 620 is a precision-engineered sacrificial anode designed primarily for cathodic protection in saltwater and brackish environments. Adhering to military specification MIL-DTL-18001L (or commercial equivalents), the Type 620 is most commonly recognized as a hull-mounted or side-frame anode for vessels ranging from tugboats to offshore supply vessels.
This datasheet provides engineers and maintenance crews with the exact electro-chemical properties, dimensional data, and installation requirements for the 620-series anode.
🔹 Applications
- Boat hulls (outboard/inboard engines)
- Shafts and rudders
- Heat exchangers
- Pipe flanges and tank interiors
- Seawater cooling systems
7. Quality Control & Inspection Checklist (Before Buying)
A legitimate datasheet includes certification. Demand these from your supplier:
- Mill Certificate (EN 10204 3.1): Proof of chemical composition.
- Electrochemical Test: Verification of 780 A·hr/kg minimum.
- Hydrogen embrittlement test: For high-strength steel applications.
- Visual Inspection:
- No "cold shuts" or casting voids.
- Smooth surface (no sand inclusions).
- Steel core centered within ±5mm.
- Core exposed properly for welding (clean of zinc splatter).
1. Chemical Composition (ASTM B418 / MIL-DTL-18001L)
To ensure active potential and prevent passivation, the Type 620 alloy must contain specific trace elements. Impurities like iron and copper are strictly limited to prevent the formation of a passive oxide film.
| Element | Composition (%) | Function |
| :--- | :--- | :--- |
| Zinc (Zn) | 99.9% Min | Base metal (Active) |
| Aluminum (Al) | 0.1 – 0.5% | Ensures uniform corrosion |
| Cadmium (Cd) | 0.025 – 0.07% | Activates the anode |
| Iron (Fe) | 0.005% Max | Prevents passivation |
| Lead (Pb) | 0.006% Max | Prevents galvanic reversal |
Note: Do not use “Pure” (unalloyed) zinc in seawater. Without Aluminum and Cadmium, the anode will coat in zinc oxide and stop working.
C. Offshore Monopiles & Wind Farms
- Retrofit: Clamped anode sleds often use 620 profiles as sacrificial inserts.
