Coat exposed steel tabs with marine epoxy, leaving the zinc body completely bare. Critical Safety Warnings
: Typical dry film thickness (DFT) of 75 microns, requiring a wet film thickness (WFT) of 120 microns. Theoretical Coverage /liter at 75 microns DFT. Heat Resistance 150 raised to the composed with power C (dry heat). Applications
Zinc anodes are the primary defense against galvanic corrosion in marine environments. The "620" designation typically refers to specific high-purity zinc alloy formulations or standardized physical dimensions used across commercial shipping, pleasure craft, and industrial marine infrastructure. zinc anode 620 datasheet
Proper installation guarantees a low-resistance electrical path between the anode and the structure. Mounting Methods
In the context of sacrificial cathodic protection, "620" refers to the overall length (mm) of specific strip-type zinc anodes used for seawater cooling systems and pipelines. Dimensions (mm) Steel Insert (mm) Net Weight (kg) 620 SRT-3 620 SRT-4 620 Coat exposed steel tabs with marine epoxy, leaving
Don't wait until the anode is gone to replace it. According to the Barnacle King's Guide
Recommended for application via airless spray , though brush or roller may be used for touch-ups and difficult shapes. Heat Resistance 150 raised to the composed with
Ensure the mounting studs are wire-brushed and clean before bolting. Replacement Schedule
