The coatings and inks market in the Asia-Pacific region is expanding rapidly, with aluminum paste being one of the fastest-growing materials. As demand accelerates, manufacturers are placing greater emphasis than ever on product stability, consistency, and long-term performance. This article will explain why stability is so important and what factors buyers must evaluate in 2025 and beyond.

Understanding Aluminium Paste and Its Rising Market Importance

Aluminum pigments are metallic pigments widely used in automotive coatings, industrial coatings, inks, and plastics. Their unique metallic luster and hiding power make them an indispensable part of cost-effective applications.

According to industry market analysis, the Asia-Pacific region accounts for more than 55% of global metallic pigment consumption, and this segment is growing at a CAGR of 6-7%, far exceeding that of Europe and North America.
This growth momentum has led to higher market demands for product stability and oxidation resistance.

Why Stability Matters More Than Ever

As Asian manufacturers scale production, product failure rates must remain extremely low. Stable aluminium paste ensures:

• Consistent metallic effect across batches

• Stable viscosity during storage

• Good dispersion in solvent-based and water-based systems

• Reduced oxidation, which otherwise causes discoloration

In high-volume industries such as automotive coatings and electronics, even small fluctuations can result in production losses or rejected batches.

result in production losses or rejected batches.

Understanding Oxidation and Color Shift Risks

One of the main threats to aluminium paste quality is oxidation.

Typical signs of oxidation

• Darkening of the metallic effect

• Lower brightness compared to fresh batches

• Gas formation in certain binders

• Loss of smooth metallic appearance

Possible causes

• High humidity during transport

• Poor solvent or resin protection

• Unstable storage temperature

• Reactive binder systems

How manufacturers prevent oxidation

• Using resin-coated aluminium paste for extra protection

• Enhancing surface passivation

• Choosing stable solvent or water-based carriers

• Strengthening packaging barriers against moisture

At ZHANGQIU METALLIC PIGMENT, our resin-coated grades undergo 48–72-hour accelerated stability testing, replicating humidity and temperature fluctuations typical in Asian shipping environments.

Meeting Asian Market Requirements

As demand expands, buyers in China, India, Vietnam, Thailand, Malaysia, and Indonesia are prioritizing:

1. Batch-to-batch consistency

Fast-growing factories require repeatable gloss and particle size. Stable aluminium paste reduces downstream QC issues.

2. Compatibility with both solvent-based and water-based systems

While Asia still relies heavily on solvent-based coatings, demand for water-based aluminium paste is increasing due to environmental standards.

3. Competitive aluminium paste price with stable quality

Rising raw materials and shipping costs push manufacturers to seek suppliers who balance cost and consistency.

ZQ Metallic’s production lines include automated screening, nitrogen protection, and micro-particle control, helping ensure ultra-stable performance across thousands of tons of annual output.

Application Comparison – Why Stability Impacts End-Use Performance

Industries most affected by aluminium paste stability

Solvent-Based vs Water-Based Performance

• Solvent-based aluminium paste → Dominate Asian usage (approx. 70–80%)

• Water-based aluminium paste → High growth rate due to VOC regulations

A stable aluminium paste ensures predictable results regardless of system type.

FAQ

Q1: Why is aluminium paste stability so important now?

Because Asia’s production volumes have increased dramatically, small defects now cause large-scale losses.

Q2: How long can high-quality aluminium paste be stored?

With proper protection, 6–12 months for standard grades and longer for resin-coated aluminium paste.

Q3: Does water-based aluminium paste have lower stability?

Modern water-based grades are engineered with anti-corrosion coatings that significantly improve stability.

Q4: What affects aluminium paste price most?

Aluminium ingot prices, particle size accuracy, surface treatment type, and solvent selection.
