Key Characteristics of Our Aluminum Paste

We carefully formulate our aluminum paste to deliver exceptional results in diverse applications:

Form and Particle Size

Our aluminum paste is a thick substance composed of fine aluminum pigment, additives, and solvents. For instance, our ZYD513 aluminum silver paste, used in agricultural film masterbatches, has a median particle size (D50) of 13μm. Particle size has a significant influence on paint performance and application, and different applications typically require specific particle size requirements for aluminum paste.

Non-Volatile Content

Our ZYD513 aluminum silver paste boasts a 70% non-volatile content. This means that 70% of the aluminum paste components remain in the paint during production, actively contributing to the paint’s properties and film formation. This significantly impacts the paint’s additivity and film-forming characteristics.

Flake Structure

The physical structure of our aluminum pigment is flake-shaped, which helps the aluminum pigment create unique optical effects in paint, such as glitter, hiding, and reflection. However, this structure also necessitates careful handling; you should avoid rapid shearing and repeated granulation during use to prevent damage to the metallic material itself and preserve its metallic texture.

The Role of Aluminum Paste in Paints Manufacturing

Our aluminum paste plays a vital role in enhancing various aspects of paints:

Imparting Unique Luster and Color Effects

Aluminum paste allows paints to exhibit unique metallic textures and shimmering effects. In applications such as automotive coatings, industrial paints, and inks, adding aluminum paste imbues the paint with metallic colors, such as silver and gray, significantly enhancing the paint’s aesthetic appeal and decorative qualities.

Enhancing Coating Hiding Power

The flake structure of our aluminum pigment creates a dense shielding layer in the paint. This effectively conceals substrate defects and colors, increasing the paint’s hiding power, reducing paint consumption, and ultimately saving costs.

Improving Coating Protection Performance

The aluminum pigment in our aluminum paste offers excellent chemical resistance. It forms a protective film on the coating surface, blocking external moisture, oxygen, and compounds from corroding the substrate. This significantly boosts the paint’s corrosion resistance and protective capabilities.

Boosting Coating Mechanical Properties

Aluminum paste enhances the paint’s hardness, wear resistance, and adhesion properties, making the coating more durable and resistant to scratches and peeling. This extends the paint’s service life.

Applications of Aluminum Paste in Paints

We widely use our aluminum paste across numerous paints manufacturing sectors:

Automotive Coatings

We use it to produce various functional automotive topcoats, such as metallic paints and pearl paints. This enhances car exteriors, making them more exquisite and high-end while also improving coating protection and durability.

Architectural Coatings

Adding aluminum paste to interior and exterior wall paints allows us to create artistic coatings with metallic textures, such as imitation aluminum panel effect coatings and metallic fluorocarbon coatings. These not only offer a unique appearance but also provide excellent weather resistance and self-cleaning functions, making them suitable for building exterior decoration and maintenance.

Industrial Coatings

We widely use our aluminum paste for the protection and decoration of metal products, mechanical parts, ships, and containers. It enhances the workpiece’s corrosion resistance and wear resistance, extending its service life.

Inks

We use it to create inks with metallic effects, such as gold and silver inks. These are suitable for packaging printing, decorative printing, and other fields, increasing products’ visual appeal.

Electronic and Electrical Coatings

Adding aluminum paste to electronic device casing coatings not only achieves a metallic appearance but also improves the coating’s electromagnetic shielding performance and thermal conductivity. This is ideal for laptop and mobile phone casings, for example.

Aluminum Paste Production Processes

We employ advanced production processes to ensure the highest quality aluminum paste:

Dry Grinding Process

This is the earliest method for producing aluminum powder from aluminum ingots, using mechanical crushing and cutting. While this process is simple and efficient, it results in a broad particle size distribution and is prone to residue. We find it suitable for paint types with low aluminum powder particle size requirements.

Wet Grinding Process

This process uses a liquid medium as the grinding environment to grind and disperse aluminum powder. This allows us to obtain aluminum powder with precise particle size and narrower distribution. Additionally, we can adjust the shape and characteristics of the aluminum powder by modifying materials and additives. This method ensures stable product quality and is one of our primary methods for producing aluminum paste.

Atomization Method

We atomize molten aluminum liquid into tiny aluminum particles using high-speed gas or water flow, then obtain aluminum powder through classification and surface treatment. Aluminum powder produced by this method has a high spherical shape, high purity, and a broad particle size distribution, making it suitable for producing high-quality aluminum paste.

Operational Guidelines for Aluminum Paste

To ensure optimal performance and safety, we advise the following operational guidelines for our aluminum paste:

Storage and Transportation

Aluminum paste is prone to mold growth when reacting with oxygen and water in the air. Therefore, ensure packaging is thorough and store it in a dry, cool, well-ventilated warehouse, away from direct sunlight and high temperatures. Handle with care during transportation to prevent packaging damage.

Dosage

Strictly control the dosage of aluminum paste based on the paint type, purpose, and desired effect. The dosage in paint is generally around 1% to 20%. Excessive amounts can lead to increased coating viscosity and prolonged drying times, while insufficient dosage will not achieve the desired metallic effect.

Mixing and Dispersion

When adding aluminum paste to paint, first mix the aluminum paste with an appropriate solvent or additive, then slowly add it to the paint. Disperse it by low-speed stirring to avoid high-speed agitation damaging the aluminum pigment and affecting its performance.

Compatibility

Aluminum paste and other components of the paint, such as resins, solvents, and additives, should have good compatibility. Otherwise, quality issues such as layering, streaking, or wrinkling may occur. Therefore, conduct comprehensive experiments and tests before use to ensure excellent compatibility between all components.

How Much Aluminum Paste Do We Typically Add in Paints Manufacturing?

The proportion of aluminum paste in paint manufacturing varies depending on the type of paint, its intended purpose, performance requirements, and the specific type of aluminum paste used. Here are some standard proportions:

General Recommended Addition Proportions

• General Paints: We generally recommend an aluminum paste addition ratio of around 4%-10% of the total paint quantity.
• Specialty Formula Paints: In some paints requiring strong metallic effects or special properties, the aluminum paste proportion may be as high as 15%-20%.

By Paint Type Classification

• Colored Metallic Paints: The addition ratio of aluminum silver paste is typically 1%-4%.
• Pure Silver Paints: The addition ratio of aluminum silver paste is typically between 4% and 10%.
• Single-Layer Metallic Flash Paints: The additional ratio of aluminum silver paste is approximately 5% to 13%.
• Anti-Corrosion Paints, Can Coatings, and Coil Coatings: The addition ratio of aluminum silver paste is around 10%-13%.
• Exceptional Cases (Aluminum Powder Paste Foam Coatings): The addition proportion of aluminum powder paste can be as high as 15-25 parts (relative to 100 parts of pure acrylic self-crosslinking cationic emulsion).
• Water-Based Paints: The addition proportion of water-based aluminum silver paste generally does not exceed 10%.
• Aluminum Powder Silicone Paints: The amount of aluminum powder used is 0.8% to 1.5% of the formula quantity.

In actual applications, paint manufacturers must determine the optimal proportion of aluminum paste through experiments and tests based on specific formulation requirements, paint performance specifications, and cost factors. At the same time, we ensure that our aluminum paste has good compatibility with other components to guarantee paint quality and performance.
