Definition of High-Performance Aluminum Paste for Automotive Coatings

Automakers require pigments that offer precise particle size control, superior stability, and a reliable metallic luster. High-quality aluminum powder ensures a narrow particle size distribution in the aluminum paste, resulting in uniform coating and excellent optical properties.

Key Technical Characteristics

• High brightness from smooth, silver-dollar-type aluminum flakes

• Consistent diameter-to-thickness ratios for clean, sharp reflections

• High-orientation aluminum flakes that align evenly in the coating layer

• Excellent weather resistance due to resin or silica encapsulation

These characteristics collectively create a metallic finish with depth and clarity—essential for today’s automotive styling trends.

Precision Manufacturing: How Quality Aluminum Paste Is Created

To achieve premium metallic effects, ZQ Metallic employs advanced atomization, surface treatment, and classification technologies.

1. Controlled Flake Geometry

Our fine-particle aluminum flake pigment is produced using:

• High-purity in-house aluminum powder

• Closed-loop milling systems

• Automated sieving for size uniformity

This improves hiding power and sparkle while reducing surface defects.

2. Surface Treatment Enhancements

To meet demanding OEM standards, we offer multiple surface-coated options:

• Silica-coated aluminum pigment for corrosion resistance

• Resin-coated aluminum paste for improved compatibility with PU, acrylic, and polyester systems

• High durability aluminum pigment for OEM coatings designed for UV and chemical stability

3. Orientation Technologies

High-orientation flake alignment is key to achieving clean metallic lines on curved automotive surfaces. Our processes minimize flake curling and maximize reflective clarity.

Frequently Asked Questions

1. Why is narrow particle size distribution important?

It ensures consistent brightness, smooth film appearance, and predictable handling in automotive lines.

2. What is the difference between leafing and non-leafing aluminum paste?

Leafing pigments float to the surface; non-leafing aluminum paste for automotive basecoat disperses evenly within the coating for stable metallic effects.

3. How does silica coating improve performance?

Silica prevents oxidation, enhances weather stability, and improves chemical resistance—critical for harsh automotive environments.

4. Can these aluminum pastes be used in waterborne systems?

Yes—our encapsulated series offers excellent stability in waterborne and high-solid systems.
