As global environmental regulations tighten, the shift toward sustainable industrial materials is accelerating. Among them, waterborne aluminium paste stands out as a high-performance, eco-friendly alternative to traditional solvent-based metallic pigments. Composed primarily of flake aluminum particles, water, and water-based solvents, this silver-white paste offers excellent water solubility, low VOC emissions, and a mild odor — making it a preferred solution across coatings, inks, and anticorrosion paints.
Waterborne aluminium paste is produced through advanced wet ball milling and surface coating technologies. Based on the behavior of aluminum flakes within the coating film, it is classified into two categories:
Floating Type: Delivers high brightness and superior corrosion resistance, making it ideal for mirror-like or electroplating-effect finishes.
Non-Floating Type: Ensures uniform distribution within the paint film, widely used in industrial and decorative coatings where consistent color and texture are essential.
A key innovation in its production is the silica coating technology, where silicate-based modification significantly enhances corrosion resistance — a critical feature for applications in harsh environments.
With a versatile particle size range of 6–75μm, waterborne aluminium paste meets diverse functional and aesthetic demands. Its adoption continues to expand across sectors:
Automotive Refinishing: Provides durable, metallic finishes while complying with emission standards.
Printing Inks & Decorative Coatings: Ensures vibrant metallic effects with minimal environmental impact.
Anticorrosion Paints: Used in marine, infrastructure, and metal protection systems.
Emerging Fields: Now applied in textiles, 3C electronic casings, and new-energy battery coatings, where both aesthetics and performance are critical.
The transition from solvent-based to waterborne aluminium paste is not just about meeting regulations — it’s also about efficiency and safety. Companies using this alternative benefit from:
Reduced VOC emissions and easier cleanup
Improved workplace safety and storage conditions
Compliance with international environmental standards (e.g., REACH, EPA)
Manufacturers and formulators looking to stay competitive are increasingly adopting waterborne aluminium paste, not only as a replacement but as an upgrade in both function and sustainability.
As industries from automotive to electronics continue to prioritize green manufacturing, waterborne aluminium paste is set to play an even larger role. With ongoing R&D focused on improving brightness, stability, and application diversity, this eco-friendly pigment is paving the way for a brighter — and cleaner — metallic finish worldwide.
