Protection mechanisms / Original product literatureShow details＋
Protection mechanisms
Four protection mechanisms—self-growth, cathodic protection, self-repair and bonding reactions—work together against corrosion.
A
Self-growing layer
The coating chemically bonds across the ferrous substrate and develops a nano self-assembled layer, isolating corrosive agents and providing strong adhesion.
B
Cathodic protection
Zinc acts as a sacrificial anode, providing continuous cathodic protection against steel corrosion, with a reported material service life exceeding 20 years.
C
Self-repair capability
Corrosion products from the sacrificial metal form sparingly soluble salts that block micropores, enabling self-repair and enhancing corrosion resistance.
D
Passivation
Strongly alkaline components promote a stable passivation layer on the ferrous substrate, improving chemical stability and corrosion resistance.

Product overview / Original literature and schematicShow details＋
Product overview
Four mechanisms of protection
A nano activation solution forms the binder, with modified sacrificial zinc powder as the solid filler and specialised rare-earth additives. Self-growth, cathodic protection, self-repair and passivation deliver reported salt-spray resistance >20,000 hours across extreme exposure from −50°C to 800°C. A single coat provides 6H hardness with a fully inorganic, zero-VOC formulation.
