🛡️ The Solution for High Performance
Zinc Flake coating represents one of the most advanced solutions in the field of protective coatings. Unlike traditional galvanizing, it is not an electrolytic process, and this “mechanical-chemical” nature makes it indispensable for certain types of applications.
🚫 Stop Hydrogen Embrittlement
Why is Zinc Flake the preferred choice for high-strength steels (such as classes 10.9 and above)?
In common electrolytic processes, the application of current can cause hydrogen absorption into the steel lattice, making it brittle and subject to sudden failure (Hydrogen Embrittlement). Zinc Flake coating eliminates this risk at its root:
- Non-Electrolytic Process: It does not require the use of current in an acid bath.
- Structural Safety: Ideal for bolts and critical components that must withstand high loads without compromising toughness.
🔬 Composition and Protective Barrier
The surface finish is not a simple uniform layer, but a complex and extremely effective structure:
- Thin Flakes: Composed of a mix of Zinc and Aluminum.
- Organic Matrix: A resin that aggregates the flakes and anchors them to the substrate.
- Barrier Effect: The flakes overlap like fish scales, creating a tortuous path that prevents corrosive agents from reaching the base metal.
The result is a thin coating that is incredibly resistant to corrosion (salt spray tests exceeding 1000 hours) and offers excellent resistance to chemical agents.
