In the global metal pigments industry, the choice of aluminum paste directly affects the final performance of coatings. With 38 years of professional experience, Shandong Yinjian Aluminum Pigment Co., Ltd. provides an in-depth analysis of the production process differences, performance characteristics, and application scenarios of leafing and non-leafing aluminum pastes, offering professional selection guidance for global customers.

Core Differences: Surface Treatment Technology and Performance

Leafing Aluminum Paste

Production Process Characteristics:
Stearic acid and other fatty acids are used for surface treatment, making the aluminum flakes hydrophobic. During production, precise control of grinding time and temperature (typically maintained at 45-55°C) ensures the formation of a uniform coating on the aluminum flake surface.

Performance Features:

• Surface arrangement: Aluminum flakes align parallel to the surface, forming a continuous metallic barrier

• Covering power: Excellent hiding performance (up to 1.5-2.0 m²/g)

• Corrosion resistance: Provides superior moisture and corrosion protection

• Appearance: Bright white metallic luster

Application Areas:

• Anti-corrosion coatings (roof coatings, marine coatings)

• Industrial protective coatings

• Reflective thermal insulation coatings

Expert Data: Our tests show that high-quality leafing aluminum paste can provide over 1000 hours of salt spray protection, far exceeding the 300-hour standard of ordinary coatings.

Non-Leafing Aluminum Paste

Production Process Characteristics:
Unsaturated fatty acids such as oleic acid are used for treatment, making the aluminum flakes lipophilic. Special degreasing processes and precise particle size control technology ensure uniform dispersion of aluminum flakes in the coating system.

Performance Features:

• Dispersion: Aluminum flakes distribute evenly within the coating

• Metallic texture: Provides strong metallic sparkle effect

• Transparency: Maintains coating transparency, suitable for color matching

• Physical properties: Improves coating mechanical strength

Application Areas:

• Automotive coatings

• Plastic coatings

• Decorative coatings

• Printing inks

Key Technical Parameter Comparison

Industry Application Selection Guide

How to Choose the Right Aluminum Paste Type?

Consideration factors:

1. Final application: Choose leafing for anti-corrosion protection, non-leafing for decorative effects

2. System compatibility: Leafing suitable for solvent systems, non-leafing has wider adaptation range

3. Cost budget: Leafing has higher cost but better protective performance

4. Environmental requirements: Both can provide water-based products

Expert advice:
"When selecting aluminum paste, we recommend conducting small sample tests first. We provide free samples and technical support to ensure the most suitable product selection."
