Bronze Powder for Printing Ink

ZQ bronze powder for ink is engineered using refined copper-zinc alloy flakes processed through precise classification and surface treatment. This ensures high metallic luster, uniform particle size, and excellent printability.

The powders are optimized for gravure, flexographic, screen, and offset inks, bringing bright gold, rich reddish-gold, and pale-gold effects to a wide range of printed substrates.

1: High Gloss and Consistent Metallic Tone

The bronze powder series (e.g., Rich Gold, Pale Gold, Reddish Gold) uses alloy compositions tailored to achieve distinct shades:

Rich Gold: Higher copper content for warm, deep metallic effects
Reddish Gold: Stronger red tone for luxury packaging
Pale Gold: Lighter tone for modern, clean visual effects

Particle sizes are strictly controlled to minimize scattering and optimize shine—an essential factor supported by industry data showing that uniform flake geometry improves metallic reflectivity by up to 25%.

2: Excellent Printability and Flow

To meet demands of high-speed printing:Smooth flake edges reduce plate wear

Narrow particle size distribution enhances leveling
Anti-settling performance improves ink stability

These properties ensure efficient pigment dispersion, uniform coverage, and stable color output during long printing runs.

3: Enhanced Oxidation and Tarnish Resistance

Using advanced surface treatment technology, ZQ bronze powder resists:

Oxidation during storage
Discoloration under UV exposure
Chemical reactions with common ink additives

Internal testing (based on accelerated aging data) shows up to 40% improvement in color retention compared with untreated bronze pigments, ensuring the metallic finish stays vibrant longer.

Frequently Asked Questions

Q1: Can bronze powder be used in water-based inks?

Traditional bronze powder is mainly for solvent-based inks, but ZQ offers modified grades suitable for selected water-based applications.

Q2: What particle size is best for high gloss?

Finer powders (e.g., 200–400 mesh) provide smoother appearance and stronger reflection.

Q3: How should bronze powder be stored?

Store in sealed containers, away from moisture and oxidizing chemicals, to maintain color stability.
