: Approximately -1.10 Volts relative to a Cu/CuSO4 reference electrode.
A poor weld ruins a perfect anode. Follow this datasheet protocol: zinc anode 620 datasheet
The 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 : Approximately -1
For maximum efficacy, proper surface preparation and application conditions are critical. zinc anode 620 datasheet
