Why Aluminium Paste Matters in Plastic Coatings

Plastic substrates such as ABS, PP, and PC require specialized metallic pigments due to their low surface energy. Standard pigments often result in poor adhesion or uneven metallic effects.

High-quality aluminium paste ensures:

• Smooth metallic finish

• Strong adhesion to plastic surfaces

• Uniform dispersion without floating issues

• Stable performance in spraying processes

Recommended Aluminium Paste Types

For plastic coatings, non-leafing aluminium paste is highly recommended because:

• It distributes evenly throughout the coating film

• It improves bonding strength with resin systems

• It enhances durability and scratch resistance

Particle Size Selection Guide

Choosing the right particle size is critical:

• 5–10 μm → smooth & fine metallic effect (electronics, 3C products)

• 10–20 μm → balanced brightness and coverage

• 20 μm+ → strong sparkle effect (industrial plastic parts)

Application Areas

This type of aluminium paste is widely used in:

• Consumer electronics coatings

• Home appliance shells

• Automotive plastic parts

• Cosmetic packaging

Why Choose a Reliable Supplier

Consistent quality is key in plastic coating production. A stable supplier ensures:

• Batch-to-batch consistency

• Controlled particle size distribution

• Customizable metallic effects
