With increasing environmental regulations and growing demand for low-VOC coatings, waterborne systems have become the mainstream choice in many industries.
As a key metallic pigment, waterborne aluminium paste plays an important role in providing brightness, durability, and decorative effects in water-based coatings and inks.
Compared with traditional solvent-based aluminium paste, waterborne aluminium paste requires advanced surface treatment and strict quality control to ensure long-term stability.
This article explains the technical features, applications, and selection guidelines for high-performance waterborne aluminium paste.
Waterborne aluminium paste is a specially treated metallic pigment designed for water-based resin systems.
Through advanced surface modification and passivation technology, aluminium flakes can:
Disperse uniformly in water
Resist oxidation and corrosion
Maintain stable metallic appearance
Reduce gas generation
Improve storage performance
These features make waterborne aluminium pigment suitable for modern eco-friendly coatings.
Modern waterborne aluminium paste uses chromium-free passivation to improve environmental safety while maintaining chemical stability.
This technology effectively prevents aluminium flakes from reacting with water and alkaline components.
Silica-coated aluminium flakes form a protective barrier on the surface, improving:
Water resistance
Chemical compatibility
Dispersion stability
Weather durability
Gas generation is a major challenge in waterborne systems.
Professional manufacturers apply low gas technology to reduce hydrogen release and prevent coating defects.
Different water-based resins require different surface treatments.
Advanced aluminium paste factories customize surface modification to match:
Acrylic systems
Polyurethane systems
Epoxy systems
Hybrid waterborne resins
High-quality waterborne aluminium paste offers several advantages:
Uniform dispersion ensures consistent metallic appearance without sedimentation.
Proper surface treatment prevents floating, darkening, and loss of brightness.
Special passivation protects aluminium flakes from moisture and chemicals.
High-grade waterborne aluminium pigment maintains performance during long-term storage.
Used in steel structures, machinery, and equipment coatings for both decoration and protection.
Applied in waterborne automotive primers, basecoats, and refinish systems.
Used in water-based gravure and screen inks for metallic visual effects.
Enhances appearance in building materials and decorative panels.
When choosing waterborne aluminium paste, consider the following factors:
Confirm compatibility with your specific resin system.
Low gas aluminium paste is essential for long-term coating stability.
Different particle sizes affect brightness and coverage.
High-quality products maintain performance under different climate conditions.
Reliable waterborne aluminium paste manufacturers implement strict quality control:
Raw material inspection
Process monitoring
Batch performance testing
Stability evaluation
Traceability systems
This ensures consistent quality for global customers.
Future development focuses on:
Ultra-low gas formulations
Bio-based surface modifiers
High weather resistance
Improved recycling compatibility
Smart production automation
These trends support sustainable coating development.
Waterborne aluminium paste is a key material for modern eco-friendly coatings and inks.
By selecting high-performance products from professional manufacturers, users can achieve excellent metallic effects, long-term stability, and environmental compliance.
Choosing reliable waterborne aluminium pigment suppliers is essential for sustainable industrial development.
