As the demand for premium metallic finishes continues to grow in automotive and industrial markets, coating manufacturers are increasingly seeking stable, high-brightness aluminium paste solutions with excellent orientation performance.

The Silver Rocket ZQ-400 Series solvent based non-leafing aluminium paste is engineered to deliver superior brightness, smooth surface appearance, and consistent particle distribution for high-grade OEM and industrial applications.

Designed with advanced in-house powder technology and strict particle control standards, this series ensures stable metallic performance across multiple coating systems.

First: What Is Non-Leafing Aluminium Paste?

Non-leafing aluminium paste is a metallic pigment where aluminium flakes distribute uniformly throughout the coating film instead of floating to the surface.

Unlike leafing aluminium paste, which forms a reflective surface layer, non-leafing aluminium paste provides:

• Uniform metallic texture

• Better intercoat adhesion

• Excellent smoothness

• Stable orientation capability

• Superior compatibility with resin systems

Because of these advantages, non-leafing aluminium paste is widely used in automotive OEM coatings, refinish systems, coil coatings, and plastic coatings.

Second: Core Characteristics of ZQ-400 Series

The ZQ-400 Series is manufactured using premium in-house spherical aluminium powder with narrow particle size distribution.

Key features include:

First, High brightness and metallic reflectivity
Second, Silver-dollar particle structure with smooth edges
Third, Consistent diameter-to-thickness ratio
Fourth, Excellent orientation capability
Fifth, Smooth and uniform paint film appearance

Advanced production equipment ensures the aluminium particles form a silver-dollar structure, which enhances light reflection and coating smoothness.

Third: Technical Performance Parameters

The ZQ-400 Series includes multiple grades to meet different brightness and application requirements.

Solvent System:
HA – High Boiling Point Aromatic Hydrocarbon Solvent

The narrow particle size distribution ensures consistent metallic effect and controlled sparkle intensity.

Fourth: Why Particle Size Matters in Non-Leafing Aluminium Paste

Particle size directly affects:

• Sparkle intensity

• Brightness level

• Smoothness of paint film

• Hiding power

Smaller particle sizes (9–11 μm) provide fine metallic texture suitable for high-grade OEM coatings.

Medium particle sizes (12–16 μm) offer balanced brightness and sparkle.

Larger particle sizes (23 μm) create stronger metallic effect and visual depth in decorative applications.

Selecting the appropriate grade ensures optimal appearance performance.

Fifth: Application Areas

The ZQ-400 Non-Leafing Aluminium Paste Series is widely used in:

High Grade Automotive OEM Coatings
Automotive Refinish Systems
Coil Coatings
Plastic Coatings
Industrial Decorative Coatings

Because of its uniform distribution behavior, non-leafing aluminium paste is ideal for multi-layer coating systems where intercoat adhesion is critical.

Sixth: Orientation and Film Smoothness Advantage

The silver-dollar aluminium flake structure provides:

• High reflectivity

• Strong orientation capability

• Smooth metallic surface

• Reduced graininess

This ensures that the final coating film maintains premium brightness and refined metallic appearance.

Seventh: Manufacturing Consistency and Supply Stability

Stable quality is essential in automotive and industrial applications.

Silver Rocket provides:

✔ Strict particle size control
✔ Advanced manufacturing equipment
✔ High non-volatile consistency
✔ Large-scale production capacity
✔ Stable global supply chain
✔ Bulk wholesale availability

With decades of experience in aluminium paste manufacturing, consistent batch-to-batch performance is guaranteed.

Conclusion

The ZQ-400 Series solvent based non-leafing aluminium paste delivers premium bright metallic effect, excellent orientation performance, and stable industrial coating compatibility.

Its silver-dollar particle structure and controlled particle size distribution make it an ideal solution for:

• Automotive OEM coatings

• Refinish coatings

• Coil coatings

• Plastic coatings
