Approximately 24.8 lbs (11.2 kg) of zinc per Ampere-year of continuous protection. Efficiency: Typically 90% to 95% in high-salinity seawater. 5. Primary Applications
The is a high-performance, two-part epoxy zinc-rich primer specifically engineered to provide superior cathodic protection for steel structures in highly corrosive environments. Often categorized by the keyword "zinc anode 620," this product functions as a "sacrificial" coating, protecting the underlying steel from rust even if the film is damaged.
The Zinc Anode 620 datasheet!
If you are writing a technical paper on the material properties of a Zinc Anode used in batteries or galvanization, here is the general technical data regarding high-purity zinc anodes (often used in electroplating or advanced Zn-air/Flow batteries). zinc anode 620 datasheet
Complies with British Standard BS 4652 and can be top-coated with epoxy, urethane, or chlorinated rubber finishes. AkzoNobel Interpon 620
This comprehensive guide serves as an expanded technical overview of what you will find in a standard Zinc Anode 620 datasheet, detailing its chemical composition, physical dimensions, performance metrics, and deployment best practices. Technical Specifications Overview
: Meets British standard BS 4652 and performance requirements for BS 5493 . Approximately 24
A compliant datasheet will typically specify the following chemical breakdown: Weight Percentage (MIL-SPEC) Purpose / Effect Remainder (approx. 99.1%+) Base metal provider of galvanic current. Aluminum (Al) 0.10% – 0.50% Promotes uniform corrosion and prevents passivation. Cadmium (Cd) 0.025% – 0.07% Aids in shedding the oxide layer to maintain activity. Iron (Fe) 0.005% max Strictly limited; high iron causes quick passivation. Lead (Pb) 0.006% max Impurity control. Copper (Cu) 0.005% max Impurity control. 3. Physical Dimensions and Mechanical Data
