How to Choose Leafing or Non-Leafing Aluminium Paste: A Buyer’s Guide for Industrial Applications

Introduction

In the metallic pigment industry, one of the most frequently asked questions is the difference between leafing aluminium pigments and non-leafing aluminium pigments. These two types of aluminium paste are widely used across coatings, inks, plastics, and industrial applications, yet they deliver very different performance characteristics.

Understanding how leafing and non-leafing aluminium pigments behave is critical for manufacturers aiming to achieve optimal coating performance, durability, and visual effects.

According to industry reports, aluminium pigments account for a major share of the global metallic pigment market, with increasing demand driven by automotive coatings, construction materials, and high-end packaging.

This guide provides a detailed comparison, technical explanation, and practical selection advice to help you choose the right aluminium paste for your application.

First: What Are Leafing and Non-Leafing Aluminium Pigments?

1.1 Definition of Leafing Aluminium Pigment

Leafing aluminium pigment is designed to float to the surface of a coating film during drying, forming a continuous metallic layer.

This effect is achieved through special surface treatment using stearic acid, which creates hydrophobic properties.

1.2 Definition of Non-Leafing Aluminium Pigment

Non-leafing aluminium pigment, on the other hand, is uniformly distributed throughout the coating film. It does not float to the surface and allows for strong bonding with the binder.

⚙️ Second: Working Principle

Step One: Leafing Mechanism

• Aluminium flakes rise to the coating surface

• Align parallel to form a reflective barrier

• Create a bright, mirror-like metallic effect

Step Two: Non-Leafing Mechanism

• Aluminium particles remain evenly dispersed

• Fully integrated with resin system

• Provide consistent metallic appearance

Third: Core Differences Between Leafing and Non-Leafing Aluminium

• Metallic car finishes

Step Two: Printing Inks

• Flexible packaging

• Labels

Step Three: Plastics

• Injection molding

• Consumer goods

Sixth: Market Data and Industry Demand

According to market research:

• Leafing aluminium pigments account for over 50% of decorative coating demand

• Non-leafing pigments dominate the automotive sector

• The global aluminium pigment market is expected to exceed USD 3.5 billion by 2030

Growth Drivers

1. Expansion of automotive industry
2. Rising infrastructure projects
3. Demand for premium packaging materials

Seventh: How to Choose Between Leafing and Non-Leafing Aluminium Paste

Selecting the right aluminium paste depends on your application requirements.

Step One: Define Application Purpose

• Decorative → Leafing aluminium

• Functional/durable → Non-leafing aluminium

Step Two: Evaluate Performance Requirements

Ask the following:

• Do you need high gloss?

• Do you require long-term durability?

• Will the coating be overcoated?

Step Three: Consider Processing Compatibility

• Solvent-based systems

• Water-based systems

• Ink formulations
