High-Performance Solvent-Based Aluminium Paste for Industrial Coatings

Solvent-based aluminium paste is one of the most widely used metallic pigments in coatings, offering excellent brightness, smooth metallic effects, and reliable dispersion stability. For industries requiring consistent performance—automotive, machinery, protective coatings—this material remains the preferred choice. 

Understanding Solvent-Based Aluminium Paste

Solvent-based aluminium paste suspends aluminium flakes in a hydrocarbon or ester-based solvent system, allowing easy mixing with various resin binders.

Key technical advantages include:

• Strong metallic brightness

• Excellent flake orientation

• High dispersion stability

• Compatibility with multiple resin systems

• Controlled viscosity and ease of formulation

According to Grand View Research (2024), the global aluminium pigment market is expected to grow at 5.7% CAGR through 2030, driven by solvent-based metallic coatings.

Engineered Brightness and Metallic Effects

1. High Gloss and Smooth Appearance

Solvent-based aluminium paste provides strong leafing or non-leafing effects depending on formula needs.
Leafing grades float to the surface for mirror-like brightness.
Non-leafing grades stay within the film for uniform metallic visuals.

Silver Rocket’s precision milling ensures:

• Narrow particle-size distribution

• High reflectivity

• Minimal graininess

2. Reliable Compatibility with Resin Systems

This aluminium paste performs well in:

• Alkyd coatings

• Nitrocellulose systems

• Acrylic resins

• Polyester topcoats

• Epoxy primers

Its solvent matrix allows easy wetting and consistent color development.

3. Stable Performance Across Harsh Conditions

Solvent-based aluminium paste shows:

• Strong water resistance

• High chemical durability

• Better UV tolerance (with proper resin selection)

These qualities make it suitable for outdoor and high-demand industrial applications.

Applications and Performance Comparison

Common Applications

• Automotive refinishes and OEM coatings

• Industrial machinery paints

• Metal protective coatings

• Wood coatings

• Aerosol sprays

• Anti-corrosion primers

Solvent-Based vs. Water-Based Aluminium Paste

Industry standards (ASTM D5894, ISO 7253) confirm solvent-based metallic coatings generally achieve higher corrosion resistance when combined with proper primers.

Frequently Asked Questions

Q1: Can solvent-based aluminium paste be used in automotive coatings?

Yes. It delivers high brightness and smooth metallic effects widely used in refinish and industrial automotive applications.

Q2: What particle size should I choose?

Fine particles = smoother, elegant metallic finish.
Coarse particles = sparkling, high-flash effect.

Q3: Do solvent-based aluminium pastes have high VOC?

They contain organic solvents, so VOC management depends on the final coating formula.

Q4: How does it disperse in resins?

It offers excellent wetting and fast dispersion, reducing mixing time.

Q5: Is it available in leafing and non-leafing types?

Yes. Silver Rocket provides both types tailored to coating performance needs.
