Resin-coated aluminium paste is becoming a preferred solution in high-performance coatings due to its stability, gloss, and compatibility advantages. By adding a protective resin layer to aluminium flakes, manufacturers can significantly improve safety, durability, and visual effect—making it ideal for both industrial and automotive applications.

What Is Resin-Coated Aluminium Paste?

Resin-coated aluminium paste is produced by encapsulating aluminium flakes with a polymer resin—often acrylic, epoxy, polyester, or polyurethane.
This coating forms a barrier that enhances oxidation resistance, improves dispersion, and provides stronger compatibility with various coating systems.

Key benefits include:

• Higher chemical resistance

• Smoother metallic appearance

• Better storage stability

• Safer processing with reduced hydrogen reaction risk

Advantage 1 – Superior Stability & Anti-Corrosion Performance

Resin-coated aluminium paste isolates aluminium flakes from moisture and alkaline systems.
This prevents common issues found in conventional aluminium pastes, including:

• Hydrogen generation

• Darkening of metallic color

• Loss of brightness

Why it matters:
Industries using water-based or acidic coatings gain a safer, longer-lasting metallic effect.

Advantage 2 – Excellent Dispersion & Lower Risk of Agglomeration

Traditional aluminium pastes can suffer from flocculation or agglomeration during mixing.
Resin-coated aluminium paste improves:

• Initial dispersion (faster and easier mixing)

• Long-term stability (reduced flake clustering)

• Compatibility with both oil-based and water-based systems

This leads to a more uniform metallic effect and a smoother surface finish.

Advantage 3 – Enhanced Orientation & High Gloss Effects

The resin layer helps aluminium flakes align better during film formation.
As a result, the coating displays:

• Stronger metallic brilliance

• Higher reflectivity

• Improved “silver-dollar” orientation

• More consistent brightness across large surfaces

This makes resin-coated aluminium paste ideal for automotive coatings, industrial paints, and high-end decorative finishes.

Applications & Performance Comparison

Typical Industries Using Resin-Coated Aluminium Paste:

• Automotive basecoats

• Industrial protective coatings

• High-grade appliances

• Powder coatings

• Water-based metallic paints

Frequently Asked Questions

Q1: Is resin-coated aluminium paste suitable for water-based coatings?
Yes. The resin layer greatly increases water resistance and prevents hydrogen reaction, making it ideal for water-based systems.

Q2: Does it cost more than standard aluminium paste?
Yes—slightly. However, improved stability, longer shelf life, and enhanced gloss often reduce total formulation cost.

Q3: Can resin-coated aluminium paste replace non-coated aluminium paste in all applications?
Not always. Some low-cost, low-performance coatings still prefer uncoated types. But for high-end or water-based coatings, resin-coated is the best choice.
