What is a Protective Plastic Coating?

A protective plastic coating is a layer we apply to material surfaces to shield them from external factors. These factors include corrosion, damage, chemical erosion, and ultraviolet radiation.

The main components primarily consist of coating resin, a curing agent, pigments, fillers, and various additives. Coating resin serves as the primary raw material, determining the fundamental properties of the coating, such as epoxy resin, polyurethane resin, and acrylic resin. The curing agent plays a leading role in the coating’s solidification process, enabling the resin to transform from a liquid to a solid state, thus forming a robust coating. Pigments provide color and specific functions; for example, anti-corrosion pigments like zinc powder enhance the coating’s anti-corrosion level. Fillers primarily function to improve the coating’s performance, such as its strength and wear resistance. Additives offer diverse functionalities; leveling agents, for instance, make the coating surface smoother, while defoaming agents prevent bubble formation during coating application.

Protective Functions and Characteristics

Protective Function: It effectively blocks contact between the substrate and harmful external substances. For example, applying a protective plastic coating to a metal surface prevents oxygen and water from reacting with the metal, thereby inhibiting rust. Using this coating on the surface of chemical pipelines prevents the transported chemicals from corroding the pipes.

Wear Resistance: Many protective plastic coatings exhibit high hardness and abrasion resistance. On surfaces frequently subjected to friction, such as equipment housings and floors, these coatings reduce surface wear and extend the service life of the substrate.

Chemical Corrosion Resistance: These coatings can resist corrosion from substances like acids, alkalis, and salts. They find widespread application in industries such as chemical processing and food production. For instance, coating the inner wall of food cans with a chemically resistant plastic coating prevents acidic and alkaline components in food from corroding the can.

Weather Resistance: Protective plastic coatings are adaptable to ultraviolet radiation and climatic conditions, such as temperature and humidity variations. On the surfaces of outdoor materials, like car bodies and advertisements, these coatings prevent the substrate from aging, fading, or becoming damaged due to prolonged exposure to sunlight and rain.

Scope of Application

Industrial Field: We widely use protective plastic coatings in industries like automotive (car body protection), shipbuilding (rust prevention for ship hulls), chemical equipment (corrosion protection for pipelines and reactors), and electronics (circuit board protection).

How Does Aluminum Silver Paste Impart Metallic Luster in Plastic Coatings?

Aluminum silver paste imparts metallic luster in protective plastic coatings through the following mechanisms:

Reflecting Light Sources: The aluminum flakes within the aluminum silver paste possess high reflectivity, enabling them to reflect light sources, including visible light and some invisible light, like a mirror. When light strikes the aluminum flakes on the coating surface, a significant portion reflects, causing the coating to exhibit a luster similar to the reflected light from a metal surface. This reflection is the primary mechanism by which aluminum silver paste imparts a metallic texture to the coating.

Scattering Light: The irregular shape and arrangement of the aluminum flakes cause light to scatter. When light encounters the aluminum flakes, in addition to reflection, scattering occurs on and around the flake surfaces, causing light to propagate in different directions. This scattering enhances the coating’s gloss and makes it appear more three-dimensional and layered, similar to the luster change of a metal surface under different viewing angles.

Covering Substrate Color: Aluminum silver paste has good hiding power and can effectively cover the color and surface defects of the substrate. Adding an appropriate amount of aluminum silver paste to the coating allows the coating surface to exhibit a uniform silvery-white metallic luster, reducing the impact of the substrate color on the coating’s appearance and making the overall coating look smoother, more beautiful, and closer to the appearance of metal.

Providing a Smooth Surface: Aluminum silver paste forms a relatively smooth surface in the coating, which is conducive to light reflection and scattering. The arrangement and distribution of aluminum flakes make the coating surface smoother and more uniform, reducing the scattering loss of light on rough surfaces and enhancing the coating’s gloss. This smooth surface effect resembles polished metal’s soft and lustrous surface.

Interaction of Optical Properties with the Coating: Aluminum silver paste interacts with other components of the plastic coating, creating a coating system with specific optical properties. The optical properties of the aluminum flakes (such as transmittance and refractive index) combine with the optical properties of the plastic substrate, causing the coating to exhibit a unique metallic texture and visual impact under certain light conditions. This interaction allows the aluminum silver paste to impart metallic luster in plastic coatings efficiently and harmonize with many properties of the coating (such as anti-aging and anti-corrosion) to enhance the overall performance of the coating.

We at Five New Materials are proud to offer aluminum silver pastes that empower protective plastic coatings with these remarkable properties. Our materials are designed to meet the demanding needs of industries seeking aesthetic appeal and robust protection.

Enhancing Performance: The consistent, fine pores generated by Five Star’s aluminum paste directly contribute to ALC’s superior thermal insulation, sound absorption, and fire resistance properties.

Optimizing Material Properties: By facilitating a controlled pore structure, our aluminum paste helps ALC manufacturers reliably achieve the target balance between low density and high compressive strength.

Why Particle Size Distribution Matters

At Five Star New Materials, we meticulously control the particle size and distribution of our aluminum paste because it directly impacts the final Autoclaved Lightweight Concrete quality:

Optical Properties (Internal Structure): While less critical for ALC than coatings, finer particles offer a larger surface area for reaction. A narrow, consistent particle size distribution ensures uniform pore formation, leading to predictable density, strength, and thermal performance in the final ALC product. Uneven distribution can lead to variations in pore size and structure.

Processing Performance: Filling & Density: A well-controlled particle distribution helps ensure the aeration process is uniform throughout the mix, contributing to a homogenous final product density and structure.

Durability Link: A uniform pore structure, initiated by consistent aluminum particles, contributes to the ALC’s overall integrity and long-term durability.

Application Performance:Dispersion: Our aluminum paste disperses easily and evenly within the ALC slurry. A narrow distribution minimizes settling variations, preventing inconsistencies and ensuring the stability and homogeneity of the mix before curing.

Reactivity Control: Optimized particle size allows for predictable and manageable reaction rates during the gas generation phase, which is crucial for controlling the rise and initial set of the ALC mixture.

Best Practices for ALC Construction

To maximize the benefits of Autoclaved Lightweight Concrete enabled by our quality aluminum paste, contractors should observe proper handling and installation techniques:

Moisture Protection: While ALC possesses some moisture resistance, designers must specify appropriate waterproofing membranes or coatings in areas prone to prolonged dampness or water exposure, such as bathrooms and kitchens.

Installation Accuracy: Ensure panels are installed level and plumb. Precise installation, especially for exterior walls, affects the building’s appearance, watertightness, and overall safety. Seal joints meticulously according to manufacturer recommendations to prevent air or water leakage.

Secure Anchoring: Follow structural engineering designs and relevant codes meticulously when anchoring ALC panels to the primary building structure. Proper anchoring guarantees stability, especially in multi-story buildings or areas with high seismic activity.

Impact Prevention: Although ALC is robust, avoid subjecting panels to sharp impacts or heavy point loads during construction and occupancy. If damage occurs, repair or replace the affected sections promptly to maintain the integrity and performance of the element.

Autoclaved Aerated Blocks (AAC)

Basic Definition and Features

Autoclaved aerated blocks (AAC) are lightweight, porous building materials made from siliceous materials (such as sand, fly ash, etc.) and calcareous materials (such as cement and lime). These materials are combined with a gas agent (such as aluminum powder) and cured under high pressure and temperature. The core features of AAC include:

Lightweight and High Strength: With a 500-800 kg/m³ density, AAC weighs only about 1/4 to 1/3 of clay bricks, reducing building weight by over 40% and improving seismic resistance.

Thermal Insulation: The thermal conductivity of AAC is 0.11-0.18 W/(m·K), which is 1/6 of regular concrete, and a 200mm thick wall offers the same insulation as a 490mm thick clay brick wall.

Excellent Workability: AAC can be sawed, nailed, drilled, and carved, providing flexibility in construction.

Fire and High-Temperature Resistance: AAC can withstand temperatures up to 600°C, meeting national fireproof standards.

Sound Insulation: The closed air voids inside AAC reduce noise transmission, making it superior to traditional materials for partition walls.

Production Process and Technological Innovations

Production Process: Raw materials undergo mixing, casting, foaming, and cutting and are cured under high pressure and temperature. The key steps include gas formation to create pores and high-pressure steam curing.

Structural Innovations: Some patented designs enhance block alignment efficiency with projections and recessed parts, while grooves improve stability. Some products feature soundproof or insulation panels on the side surfaces.

Application Areas

Building Types: AAC is widely used for interior and exterior wall partition walls in residential and commercial buildings, particularly for high-rise frame structures, earthquake-prone areas, and soft soil foundations.

Limitations: AAC should not be used in regions permanently submerged below ±0.00 level, in strong acidic or alkaline environments, or on surfaces exposed to temperatures exceeding 80°C.

Comparison of Advantages and Disadvantages

AdvantagesDisadvantagesEnergy-saving and environmentally friendly (high utilization rate of industrial waste)High water absorption (requires waterproofing treatment, prohibited in humid areas)Convenient construction (standardized dimensions, reduced wet operations)Low surface strength (easily damaged, transportation requires caution)Low comprehensive cost (reduced foundation investment, increased usable area)Limited durability (prone to cracking with long-term exposure)

Quality Standards and Testing

The Role of Aluminum Paste in AAC Production

Difference Between Aluminum Paste and Aluminum Paste Slurry

Aluminum Paste: Made by grinding aluminum powder with a solvent (such as mineral oil or water), it is mainly used for paints, inks, and other applications that require metallic luster and corrosion resistance.

Aluminum Paste Slurry: Specifically used in AAC production as a foaming agent, this slurry contains aluminum powder and additives mixed into a paste form to release hydrogen gas, forming a porous structure.

Function of Aluminum Paste Slurry in AAC Production

Foaming Mechanism: When aluminum paste slurry reacts with water in an alkaline slurry, it generates hydrogen gas, forming an even pore structure.

2𝐴𝑙+3𝐶𝑎(𝑂𝐻)2+6𝐻2𝑂→3𝐶𝑎𝑂⋅𝐴𝑙2𝑂3⋅6𝐻2𝑂+3𝐻2↑2Al+3Ca(OH)2​+6H2​O→3CaO⋅Al2​O3​⋅6H2​O+3H2​↑

Advantages of Aluminum Paste Slurry:

Safety: The use of oil—or water-based mediums eliminates the explosion risk present in dry grinding aluminum powder.

Ease of Use: The paste form makes it easier to measure and mix, reducing dust pollution and increasing production stability.

Cost Control: Using aluminum foil scraps reduces production costs.

Suitability of Aluminum Paste in AAC Production

Limitations: Aluminum paste is coated with a protective layer (such as stearic acid), which prevents water reactions and leads to insufficient foaming or failure. This makes it unsuitable as a substitute for aluminum paste slurry.

Potential Improvements: Chemically removing protective layers could reactivate the aluminum powder, though this process is complex and costly.

Future Development: The focus is on developing composite materials that combine foaming and decorative properties, but the balance between pore stability and aesthetic appearance must be maintained.

Quality Control in Production

Choosing Aluminum Paste Slurry: I prefer a water-based slurry (meeting JC/T 407 standards) for its superior environmental friendliness. Ensure that the active aluminum content is ≥90% and the particle size is 40-80μm for balanced foaming speed and pore uniformity.

Process Parameter Optimization: Control slurry temperature between 45-55°C for consistent foaming and thickening. Typical slurry dosage is 0.08%-0.12% by dry material weight, with excess causing interconnected pores or collapse.

Industry Trends and Innovations

Engineering Applications: Companies like Guangxi Zhongyu use aluminum paste slurry to produce AAC with a pore rate ≥70% and compressive strength A3.5-A5.0.

Technological Innovations: Research into high-strength foaming agents, such as low-oxidized aluminum paste slurry (A7.5 grade), expands AAC applications for load-bearing walls. Combining aluminum paste slurry with nanomaterials could improve thermal and acoustic insulation properties.

Autoclaved Aerated Concrete Blocks Aluminum Paste: Key Information and Benefits

Autoclaved Aerated Concrete (AAC) blocks aluminum paste is a key gas-generating material used in the production of Autoclaved Aerated Concrete. Through a chemical reaction, it forms a uniform pore structure within the concrete, granting the blocks characteristics such as light weight, thermal insulation, and heat resistance. Below is a detailed breakdown of its core information:

1. Mechanism of Aluminum Paste

Gas Generation and Porous Structure Formation The active aluminum powder in aluminum paste reacts with water in an alkaline environment, releasing hydrogen gas and forming a gel-like aluminum hydroxide. This process creates closed pores, significantly reducing the density of the blocks to 500-700 kg/m³, only one-fifth of ordinary concrete, while also enhancing thermal insulation properties.

Lightweight and Strength Improvement The porous structure reduces the weight of the blocks, cutting down building loads by over 40%. The even distribution of pores and the reasonable thickness of the pore walls ensure that the compressive strength can reach over 25 MPa, making Autoclaved Aerated Concrete blocks suitable for both load-bearing and non-load-bearing walls.

Improved Construction Performance The expansion of the slurry induced by the aluminum paste reaction makes the blocks easier to cut and process, reducing the amount of cement used and lowering production costs.

2. Aluminum Paste Production Process

Raw Material Treatment Aluminum ingots or aluminum foil scraps need to be screened to remove oxidation layers and ensure uniform granularity. When ball-milling, additives such as dispersants and corrosion inhibitors are used to enhance grinding efficiency and aluminum powder activity.

Ball Milling and Dehydration The materials are finely milled to a particle size of ≤0.075 mm using a specialized ball mill. The water is then removed using a dehydration press, resulting in aluminum paste, which is packed and stored.

Environmental Process Optimization Modern processes substitute traditional dry methods with tap or well water, reducing pollution and energy consumption. Some companies (like Baisheng Aluminum) utilize patented equipment to enhance efficiency, allowing for the dehydration and bagging of five machines per hour.

3. Technical Parameters and Standards

Key Performance Indicators

Solid content: ≥65% (GLS-65) or ≥70% (GLS-70)

Active aluminum content: ≥90% (ensuring gas generation efficiency)

Comparing Autoclaved Aerated Concrete Blocks Aluminum Paste with Other Insulation Materials

Autoclaved Aerated Concrete (AAC) blocks aluminum paste has substantial advantages over other common insulation materials like EPS, rock wool, and ALC panels. Here’s a comparison analysis:

1. Lightweight and Structural Performance

Lightweight and Compressive Strength The dry density of Autoclaved Aerated Concrete blocks is 500-700 kg/m³, only one-fifth of regular concrete and one-third of clay bricks, significantly reducing building loads. Additionally, the compressive strength can reach 3.5-7.5 MPa, sufficient for both non-load-bearing and some load-bearing walls. In comparison, EPS and XPS, although lightweight, have lower strength and require composite structures. Rock wool panels have weak compressive performance and can deform when exposed to moisture.

Seismic Resistance The porous structure results in low seismic inertia. During the Tangshan earthquake, Autoclaved Aerated Concrete buildings only sustained minor cracks, while brick-concrete structures nearly collapsed. AAC blocks outperform traditional materials in seismic performance.

2. Thermal Insulation Performance

Low Thermal Conductivity With a thermal conductivity of 0.11-0.18 W/(m·K), a 20cm Autoclaved Aerated Concrete block wall provides the same insulation as a 49cm clay brick wall, far surpassing EPS (0.03-0.04 W/(m·K)) and rock wool (0.04-0.05 W/(m·K)).

Thermal Inertia and Adaptability High-density products can increase thermal inertia in the south, while low-density products reduce thermal conductivity in the north, adapting to different climates. Traditional insulation materials like EPS require additional thickness adjustments, adding complexity to construction.

3. Fire Resistance and Safety

Grade A Fire Resistance Autoclaved Aerated Concrete is an inorganic material with a fire resistance limit of over 3 hours, meeting national first-class fire resistance standards. EPS, on the other hand, is classified as B1/B2 and releases toxic gases when exposed to fire. Rock wool is also grade A, but it is more expensive.

No Risk of Cavities or Shedding Autoclaved Aerated Concrete blocks are monolithic, eliminating the need for external insulation layers and avoiding potential risks of detachment in composite systems like EPS, which require anchoring and may crack over time.

4. Environmental and Economic Benefits

Resource Recycling The materials used, such as fly ash and slag, account for over 75% of the raw materials, reducing solid waste and meeting green building standards. EPS relies on petrochemical products, and rock wool has high production energy consumption.

Lower Overall Cost The unit price of AAC blocks is around 145-200 RMB/m³, with wall construction costs approximately 75 RMB/m², lower than EPS exterior insulation systems (around 120 RMB/m²). While ALC panels offer fast construction, their material costs are 30%-40% higher.

5. Construction and Functionality

Ease of Construction Autoclaved Aerated Concrete blocks are easy to saw, nail, and plane, simplifying the process without complex columns and beams. In contrast, rock wool panels require special cutting tools, and EPS needs fireproof isolation strips, increasing construction difficulty.

Soundproofing and Water Resistance The internal pores of Autoclaved Aerated Concrete blocks absorb 41 dB of noise and have excellent water resistance, absorbing moisture five times slower than clay bricks. EPS has poor soundproofing, and rock wool’s performance decreases when exposed to water.

6. Comparing New Materials

ALC Panels: Although ALC panels offer superior soundproofing and fire resistance and are quick to construct, their cost (about 70 RMB/m²) is significantly higher. Autoclaved Aerated Concrete blocks provide a better cost-performance ratio for low-rise buildings.

STP Vacuum Insulation Panels: With a thermal conductivity as low as 0.008 W/(m·K), these panels are highly efficient but are expensive (around 100 RMB/m²) and require full adhesion for installation, limiting their application.

Autoclaved Aerated Concrete Blocks aluminum paste offers balanced performance across lightweight, insulation, fire resistance, environmental sustainability, and cost. It is especially ideal for buildings with high energy efficiency and safety requirements. Although ALC panels and STP panels excel in specific scenarios, AAC remains the most cost-effective insulation solution in terms of performance for most building projects.

In today’s competitive and climate-conscious construction industry, the choice of materials matters more than ever. As we’ve explored in this blog, aluminum paste is not just a chemical additive—it is the foundation of AAC’s revolutionary properties. From reducing building loads and enhancing energy efficiency to delivering superior fire safety and seismic resilience, aluminum paste empowers AAC blocks to outperform traditional and alternative insulation materials in nearly every category.

Differences in Aluminum Paste Use for Original and Repair Paints

1. Material Characteristics and Requirements

Original Paint: Original automotive paints require high-quality aluminum paste with high granularity, symmetrical particle size, excellent purity, and stability. Since original paints undergo high-temperature baking (typically above 130°C), the aluminum paste’s high-temperature resistance is crucial.

Repair Paint: Aluminum paste used in repair paints must meet specific requirements for particle size, coverage, and granularity. However, repair paints are usually cured at lower temperatures (around 80°C) or air-dried, making heat resistance less critical.

2. Coating Structure and Process

Original Paint: Original automotive coatings consist of electrophoretic layers, intermediate layers, topcoats, and surface coatings. Aluminum paste is widely used in topcoats to provide even metallic texture and decorative finishes. Automatic spray equipment is typically used to ensure even distribution and strong adhesion.

Repair Paint: Repair coatings usually consist of only partial layers, topcoats, and surface coatings and often lack an electrophoretic layer. Manual application of repair paint may lead to uneven distribution and weaker adhesion of aluminum paste.

3. Performance

Original Paint: Due to high-temperature baking and strict process controls, aluminum paste in original paints offers stronger adhesion, better corrosion resistance, and improved scratch resistance, providing more durable decorative finishes.

Repair Paint: Aluminum paste in repair coatings may have slightly lower durability and adhesion, and in complex construction conditions, issues such as color discrepancies and orange peel may arise.

4. Primary Uses

Original Paint: Used primarily in car production, original paints require high-quality coatings that meet stringent temperature and application standards.

Repair Paint: Used for repairing damaged car finishes, repair paints offer more flexibility but cannot achieve the same effects as original paints due to material and process limitations.

The main differences in aluminum paste usage between original and repair paints are material quality, process standards, performance, and primary applications. Original paint aluminum paste prioritizes high-temperature stability and decorative finishes, while repair paint aluminum paste focuses on construction convenience and cost control.

Bonding Differences Between Repair and Original Paint Aluminum Paste

The differences in aluminum paste bonding between repair and original automotive paints are as follows:

Baking Temperature:

Original paint undergoes high-temperature baking, at least at 130°C, which strengthens the bond between the aluminum paste and the paint layer. Repair paint is typically baked at lower temperatures (around 80°C), weakening bonds.

Topcoat Process:

Original paint uses electrophoretic methods, providing strong adhesion and corrosion resistance. In contrast, repair paint often uses phosphating treatment, resulting in lower adhesion and corrosion resistance than original paint.

Material Quality:

The aluminum paste used in the original paint is of higher quality, providing excellent bonding. Repair paints use aluminum paste of lower quality, which may lead to reduced adhesion.

Application Process:

Original paints are applied using automatic spray equipment, ensuring even distribution and firm adhesion of aluminum paste. Repair paints are often applied manually, which may result in uneven distribution and lower adhesion.

Original paint has a clear advantage in aluminum paste bonding due to higher baking temperatures, electrophoretic processes, superior material quality, and automated application.

How Does Aluminum Paste Quality Affect Adhesion?

The quality of aluminum paste directly impacts adhesion. Here is a detailed analysis:

Aluminum Paste Characteristics

Coverage: If the aluminum paste lacks good coverage or the low-quality aluminum paste is chosen, the bonding strength will be compromised during the blending process.

Formula Rationality: The proportion of aluminum paste in the formula or excessive use of silicon additives can cause silver flake shedding, weakening the adhesion.

Resin Selection: If the chosen resin does not encapsulate the aluminum paste effectively, silver flakes will detach during handling or application, reducing adhesion.

Physical Characteristics of Aluminum Paste

Particle Size and Distribution: The size and uniformity of the aluminum paste particles affect its water permeability and contact surface with the substrate. Larger particles lead to uneven distribution, which damages adhesion, while smaller particles increase costs and complicate handling.

Purity: The higher the purity of the aluminum paste, the fewer impurities it contains, resulting in better compatibility with the paint and stronger adhesion. Excessive residuals can weaken the fusion between aluminum paste and paint, reducing adhesion.

Stability: The reliability of aluminum paste during storage and usage, including resistance to clumping or mold formation, can affect its performance and adhesion.

Compatibility Between Aluminum Paste and Paint

The compatibility between aluminum paste and paint is a key factor for adhesion. Poor compatibility prevents the aluminum paste from dispersing evenly, leading to uneven coatings and reduced adhesion. Good mixing performance enhances the uniform distribution of aluminum paste within the paint system, improving both adhesion and overall performance.

Surface Treatment of Aluminum Paste

Aluminum paste undergoes surface treatments to enhance its compatibility and adhesion. Specific resin coatings or additives improve wettability, permeability, and adhesion, thus boosting overall performance.

Drying and Curing Characteristics

The drying and curing characteristics of aluminum paste also play a vital role in adhesion. Over-drying can create stress between the paint film and substrate, weakening adhesion. Poor or rapid curing can also impair the fusion between aluminum paste and paint, reducing adhesion.

The quality of aluminum paste significantly influences adhesion through its physical properties, compatibility with the paint, and the drying and curing process. High-quality aluminum paste leads to better adhesion, while inferior paste may compromise the finish and durability.
