In the evolving world of metallic pigments, understanding aluminum paste varieties has become crucial for manufacturers across industries. Shandong Yinjian Aluminum Pigment Co., Ltd., with 38 years of specialized experience, presents an authoritative overview of aluminum paste classifications and their optimal applications.

Understanding Aluminum Paste Fundamentals

Aluminum paste, composed of finely divided aluminum flakes suspended in appropriate carriers, offers unique metallic effects that vary significantly by type. The key differentiation factors include:

• Particle size distribution (5-45μm range)

• Surface treatment (leafing vs non-leafing)

• Carrier system (solvent-based vs water-based)

• Specialized additives for enhanced performance

Primary Classification Categories

1. Leafing vs Non-Leafing Aluminum Paste

Leafing Aluminum Paste

• Characteristics: Surface-treated with stearic acid, floats to coating surface

• Advantages: Excellent metallic brightness, superior corrosion protection

• Applications: Protective coatings, roof coatings, industrial finishes

• Yinjian Recommendation: LF-200 series for optimal leafing performance

Non-Leafing Aluminum Paste

• Characteristics: Treated with oleic acid, disperses throughout coating film

• Advantages: Better adhesion, chemical resistance, transparency

• Applications: Automotive coatings, plastic coatings, printing inks

• Yinjian Recommendation: NL-300 series for versatile applications

2. Particle Size-Based Classification

*Fine Particle Paste (5-15μm)*

• Visual Effect: Smooth, satin-like finish

• Applications: Automotive topcoats, premium packaging

• Coverage: 1.2-1.8 m²/g

*Medium Particle Paste (15-25μm)*

• Visual Effect: Balanced sparkle and coverage

• Applications: General industrial coatings, printing inks

• Coverage: 0.8-1.2 m²/g

*Coarse Particle Paste (25-45μm)*

• Visual Effect: High sparkle, dramatic metallic effect

• Applications: Textured coatings, specialty effects

• Coverage: 0.5-0.8 m²/g

Advanced Specialty Categories

Water-Based Aluminum Paste

• Technology: Silica encapsulation for corrosion prevention

• Advantages: Low VOC, environmental compliance

• Applications: Eco-friendly coatings, indoor applications

• Yinjian Innovation: WB-500 series with enhanced stability

Plastic-Compatible Paste

• Features: Excellent dispersion in polymer matrices

• Advantages: No gas generation, easy processing

• Applications: Injection molding, plastic coatings

• Yinjian Solution: PL-600 series for plastic applications

High-Temperature Resistant Paste

• Capability: Withstands up to 400°C processing

• Applications: Coil coatings, high-bake systems

• Yinjian Specialty: HT-700 series for demanding conditions
