: The backfill lowers contact resistance and moisture retention around the anode.
: Contains over 80% zinc by weight in the dry film. zinc anode 620 datasheet
Use respirators during spray application and avoid skin/eye contact. For full safety details, refer to the Berger Safety Data Sheet . Berger Zincanode 620
The Zinc Anode 620 is a that protects more noble metals (e.g., steel, aluminum) from galvanic corrosion. Because zinc has a more negative electrode potential (−1.05 to −1.10 V) than steel (−0.85 V), it acts as the anode in an electrochemical cell when connected and submerged in an electrolyte.
