Zinc Flake
Advanced Anti-Corrosion Pigment with Enhanced Coating Performance
Zinc flake pigments offer a next-generation solution for anti-corrosion coatings, delivering superior protection with optimized material efficiency.
Structural Advantage
Due to their lamellar (flake-shaped) structure, zinc flakes provide:
- Significantly higher specific surface area than spherical zinc dust
- Lower pigment volume concentration in formulations
- Higher binder content, resulting in improved coating performance
- Reduced zinc content in paint while maintaining corrosion resistance
- Improved edge and corner protection
- No blistering during service life
- Smooth and uniform surface finish
- Lower coating weight
- Greater coating flexibility
- Enhanced adhesion to substrates
- Excellent overcoatability
- Low porosity and permeability
- Metallic appearance
- Minimal sedimentation
- Easily re-stirrable pigments during storage
Advantages of Zinc Flake Coatings
These properties make zinc flake coatings particularly suitable for high-performance and long-life anti-corrosion systems.
Packaging Options
