is a two-component, high-solids epoxy primer. It provides "galvanic protection" by acting as a sacrificial layer; if the coating is scratched, the high concentration of zinc dust corrodes instead of the underlying steel.
Key Composition: Contains over 80% zinc by weight in the dry film.
Compliance: Meets British standard BS 4652 and performance requirements for BS 5493. zinc anode 620 datasheet
Industrial Use: Commonly used on offshore structures, petrochemical plants, pipelines, and bridges. Technical Data & Specifications
The following technical metrics are standard for the Zincanode 620 Datasheet: Specification Volume Solids Typical Dry Film Thickness (DFT) 75 microns Theoretical Coverage m2m squared /litre @ 75 microns DFT Finish & Color Matt, Metallic Grey Mixing Ratio 3 parts Base : 1 part Hardener (by volume) Heat Resistance Up to 150°C (Dry heat) Application Guidelines
Surface Preparation: Requires abrasive blast cleaning to a minimum standard of Sa 2.5 (ISO 8501-1:1988) with a surface profile between 50 and 75 microns.
Method: 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
While "620" is primarily a coating brand, some maritime suppliers use similar numbering for solid anodes. For example:
Marine Pencil Anodes: Some Bukh engine pencil anodes use part numbers like 2-62050 for small engine-cooling protection.
Dimensions: Large hull anodes, such as the NAL 8 model, can have lengths of 620mm and weigh approximately 8kg. Go to product viewer dialog for this item. Zinc Pencil Anode
