Corn-flake aluminium paste is a critical metallic pigment used in automotive coatings, industrial paints, plastics, and printing inks. Its unique flake morphology delivers excellent coverage, brightness, and metallic effects.
This article explains its structure, advantages, and application value—based on industry expertise and global standards.
Corn-flake aluminium paste is produced through controlled ball-milling and surface treatment.
Its round-edged, corn-like flake structure enhances light reflection and provides consistent metallic orientation.
According to ISO 18451 and ASTM D6580 pigment performance guidelines, flake shape is the determining factor for brightness, hiding power, and leafing behavior—which is why corn-flake pigments are widely used in high-performance coatings.
Corn-flake aluminium paste achieves a balanced structure between brightness and coverage.
Uniform particle size distribution
Smooth flake edges
Excellent leveling and orientation
Moderate to high brightness
Strong compatibility with multiple resin systems
These properties make it suitable for fields requiring stable metallic appearance without extreme sparkle.
Advanced passivation and resin coating technologies improve the pigment’s durability.
Improved solvent resistance
Better oxidation resistance
Stable aluminum–resin interaction
Lower gas formation in sensitive systems
According to Coatings World Market Data 2024, surface-treated aluminium pigments increase coating durability by 40–60% in aggressive environments.
Corn-flake aluminium paste fits into a wide range of applications due to its performance balance.
Automotive refinishing coatings
General industrial metallic coatings
Plastic masterbatch systems
Printing inks & decorative paints
Bicycle and hardware metallic finishes
Manufacturers choose corn-flake pigments when they need high hiding power, soft metallic effect, and strong stability.
Below is a simplified performance comparison based on common industry metrics.
| Feature | Corn-Flake Aluminium Paste | Silver Dollar Aluminium Paste | Regular Aluminium Paste |
|---|---|---|---|
| Brightness | Medium–High | High–Premium | Medium |
| Coverage | High | Medium | Medium |
