Water-Based Aluminium Paste is a specially engineered metallic pigment designed for waterborne coating systems. It is manufactured using aluminium powder with a narrow particle size distribution and undergoes inorganic surface treatment to minimize gas generation during formulation.
Compared with conventional solvent-based aluminium paste, this series offers:
Reduced gas evolution
Improved storage stability
Excellent dispersion compatibility
Compliance with low-VOC coating systems
The product can be produced in passivated, single-coated, or double-coated types depending on the end-use application.
Water-based aluminium paste is developed to ensure:
Stable aluminum flake structure
Inorganic surface treatment (SiO₂ coating)
Controlled particle size distribution
Strong compatibility with waterborne resins
Long-term storage stability
When properly formulated in the selected resin system, it maintains consistent metallic effect and application performance.

This water-based aluminium paste series is widely used in:
OEM waterborne coatings
Refinish coatings
Coil coatings
Plastic coatings
Decorative industrial coatings
Because of the SiO₂ surface treatment, the aluminum flakes demonstrate enhanced chemical resistance and improved compatibility in waterborne systems.
The D50 particle size directly influences:
Metallic brightness
Sparkle intensity
Hiding power
Surface smoothness
Smaller particle sizes (5–9 μm) produce fine metallic finishes suitable for plastics and decorative coatings.
Medium sizes (11–17 μm) balance brightness and smoothness for OEM applications.
Larger sizes (30–40 μm) create stronger metallic sparkle effects.
Selecting the appropriate grade depends on coating thickness, resin system, and aesthetic requirements.
Due to inorganic passivation treatment:
Hydrogen gas generation is significantly reduced
Storage stability is improved
Long-term dispersion consistency is maintained
Proper storage conditions:
Keep sealed
Store in cool, dry place
Avoid direct sunlight
Water-Based Aluminium Paste represents a critical solution for environmentally compliant coating systems. With controlled particle size, SiO₂ surface treatment, and stable metallic effect, it supports modern waterborne coating technologies across OEM, coil, and decorative applications.
Choosing the correct grade ensures optimal metallic performance and long-term coating durability.
