When sourcing aluminum paste for coatings or inks, one of the most common questions is:
What is the difference between leafing and non-leafing aluminum paste?
Understanding this distinction is essential for selecting the right metallic pigment and achieving the desired coating performance.
Leafing aluminum paste is designed to float to the surface of the coating film.
Forms a reflective metallic layer
Produces strong brightness and mirror-like effect
Excellent light reflectivity
Spray paints
Decorative coatings
Roof coatings
Anti-corrosion coatings (temporary protection)
Because the aluminum flakes align on the surface, leafing aluminum paste delivers maximum metallic effect.
Non-leafing aluminum paste distributes evenly throughout the coating layer.
Uniform dispersion
Better adhesion with resin systems
Strong durability and corrosion resistance
Automotive coatings
Industrial coatings
Coil coatings
Plastic coatings
Compared with leafing types, non-leafing aluminum paste offers more stable long-term performance.
| Property | Leafing Aluminum Paste | Non-Leafing Aluminum Paste |
|---|---|---|
| Position in film | Surface | Inside coating |
| Brightness | Very high | Moderate to high |
| Durability | Lower | Higher |
| Corrosion resistance | Limited | Strong |
| Application | Decorative | Functional coatings |
Choosing between leafing and non-leafing aluminum paste depends on your application:
If you need high brightness and metallic appearance → choose leafing
If you need durability and corrosion resistance → choose non-leafing
For automotive coatings → usually non-leafing
For spray paints or decorative coatings → leafing is preferred
Using leafing paste in systems requiring strong adhesion
Ignoring compatibility with resin systems
Choosing incorrect particle size for the application
These mistakes can lead to poor coating performance or instability.
