Questions&Answers about aluminium paste applications
1. What is aluminium paste?
Answer:Aluminium paste is a metallic pigment made from fine aluminium powder flakes mixed with a solvent or carrier (such as mineral spirits, glycol, or water-based mediums). It is used to create a metallic appearance, improve reflectivity, and provide functional properties in different applications.
2. What are the main applications of aluminium paste?
Answer:Aluminium paste is mainly used in:
● Automotive coatings – metallic car paints and finishes
● Industrial coatings – machinery, equipment, and protective paints
● Architectural coatings – decorative metal-effect paints
● AAC (Autoclaved Aerated Concrete) blocks – hydrogen gas generation for pore formation
● Printing inks – metallic effects on packaging and labels
● Plastic coatings – metallic appearance
● Fire-resistant coatings – reflective and heat-resistant layers
● Solar and reflective coatings – improving light and heat reflection
3. Why is aluminium paste used in AAC block production?
Answer:In AAC production, aluminium paste reacts with calcium hydroxide in the cement/lime mixture to release hydrogen gas. The gas forms tiny pores inside the concrete, making the blocks lightweight and improving thermal insulation.
Reaction:
4. What is the difference between aluminium paste and aluminium powder?
Answer:
Aluminium Paste
Aluminium Powder
Aluminium flakes dispersed in liquid carrier
Dry aluminium particles
Easier and safer handling
Higher dust risk
Better dispersion in coatings
Requires more mixing
Used directly in many paint systems
Used for special formulations
5. What types of aluminium paste are available?
Answer:Common types include:
1. Leafing aluminium paste
○ Aluminium flakes float to the surface
○ Gives strong metallic shine
○ Used in protective coatings
2. Non-leafing aluminium paste
○ Aluminium flakes distribute evenly
○ Better durability
○ Used in automotive and industrial paints
3. Water-based aluminium paste
○ Used in environmentally friendly coatings
4. AAC grade aluminium paste
○ Designed for gas generation in concrete production
6. How do you choose the correct aluminium paste grade?
Answer:Selection depends on:
● Application purpose
● Particle size
● Aluminium content
● Solvent compatibility
● Required brightness
● Chemical stability
● Surface finish requirements
Example:
● AAC blocks → AAC-grade paste
● Car paint → high-brightness non-leafing paste
● Heat-resistant coating → leafing paste
7. What factors affect aluminium paste performance in coatings?
Answer:Important factors include:
● Particle size distribution
● Aluminium purity
● Paste concentration
● Mixing speed
● Resin compatibility
● Storage conditions
● Film thickness
8. How should aluminium paste be stored?
Answer:
● Store in a cool, dry place
● Keep container tightly closed
● Avoid direct sunlight
● Avoid contact with water (for solvent-based grades)
● Avoid strong acids and alkalis
● Do not freeze water-based products
9. How is aluminium paste added into paint?
Answer:
Typical process:
1. Prepare resin/solvent system
2. Add aluminium paste slowly
3. Mix gently at low speed
4. Avoid excessive shear force
5. Adjust viscosity and application properties
High-speed mixing may damage aluminium flakes and reduce metallic effect.
10. What problems can occur when using aluminium paste?
Answer:
Problem
Possible Cause
Poor metallic effect
Wrong grade or damaged flakes
Sedimentation
Poor dispersion or storage
Color change
Chemical reaction
Low AAC expansion
Incorrect dosage or mixing
Surface defects
Poor compatibility
11. What is the typical dosage of aluminium paste in AAC blocks?
Answer:The dosage depends on the formula and aluminium content, but commonly it is around:
0.05%–0.10% of total dry materials
The exact amount must be adjusted according to density, raw materials, and expansion requirements.
12. How can aluminium paste quality be tested?
Answer:Common tests include:
● Aluminium content test
● Particle size analysis
● Viscosity measurement
● Hydrogen generation test (AAC grade)
● Metallic appearance test
● Stability test
● Chemical composition analysis
13. What are the advantages of aluminium paste?
Answer:
● Excellent metallic appearance
● High reflectivity
● Lightweight
● Good heat reflection
● Easy dispersion
● Wide industrial applications
14. What safety precautions are needed?
Answer:
● Avoid inhalation of aluminium dust
● Use protective gloves and goggles
● Keep away from ignition sources (especially dry aluminium powder)
● Follow SDS instructions
● Handle according to local chemical regulations
15. What information should a customer provide when buying aluminium paste?
Answer:
Customers should specify:
● Application (AAC, paint, ink, coating, etc.)
● Required aluminium content
● Water-based or solvent-based system
● Desired brightness
● Packaging requirement
● Monthly consumption
● Target market regulations

Aluminum silver sand/Flaky aluminium pigments, is a flaky metallic pigment made of high-purity aluminum powder processed by special ball milling and surface treatment technology. It presents irregular granular silver metallic luster, featuring strong three-dimensional texture, prominent grainy effect and excellent metallic feel.
This product boasts good dispersion, outstanding hiding power, stable weather resistance and anti-floating performance. It can form uniform granular silver texture on coating surface after construction. Widely applied in solvent-based coatings, plastic coatings, ink, leather finishing, art paint, architectural coatings and handicraft surface decoration.
Different particle sizes deliver distinct texture effects: coarser grades create obvious rough grain texture, while finer specifications offer delicate fine sand metallic effect. Compatible with most resin systems. Proper dispersion process is required to avoid flocculation and achieve ideal grain presentation.
