Five Core Product Lines, Precisely Meeting Professional Demands

1、Automotive Wheel Rim Powder Coatings

•  AAB Group’s wheel rim primer uses advanced technology, specifically optimized for the surface characteristics of aluminum alloy wheels. This coating system provides superior adhesion, ensuring that subsequent layers (such as topcoats and clearcoats) firmly bond and are protected from peeling, delamination, or bubbling.

• AAB primer offers excellent corrosion resistance, particularly in environments exposed to salt spray, chemicals, and high humidity. It effectively resists prolonged saltwater corrosion, protecting aluminum alloy wheels from oxidation and rust, thus extending their service life.

• The primer creates a strong bond with the aluminum alloy surface, ensuring long-term coating stability. Test results show that AAB primer’s adhesion meets international standards (such as ASTM D3359), preventing coating detachment even under harsh environmental and high-temperature conditions.

• AAB wheel rim primer provides a solid foundation for subsequent coatings, enhancing not only adhesion but also the overall abrasion resistance of the coating system. Even under high-stress conditions, the primer’s coating resists scratching and wear, maintaining the wheel's appearance and functionality.

2、Engine and Chassis Component Powder Coatings

• Excellent high-temperature resistance, resistance to oil and chemical corrosion, and salt spray performance.

• Provides long-lasting protection for engine compartment parts, suspension systems, brake components, and chassis structures, effectively extending service life.

• The coating remains stable in high-temperature, high-humidity, chemical, and mechanical stress environments.

3、Automotive Structural and Functional Component Powder Coatings

• This product line is specially designed to tackle extreme chemical corrosion environments (verified through both laboratory and real-world testing). It provides exceptional protection against corrosive substances, making it suitable for parts like brake cables, engine blocks, steel leaf springs, and other engine compartment components. The coating ensures high corrosion resistance and wear resistance while also maintaining flexibility and adhesion.

• It is suitable for key parts like seatbelt anchor points, seat frames, battery trays, and motor housings.

• Meets the coating requirements for lightweight automotive materials, providing solutions that combine protection with lightweight design.

4、Automotive Body Clear Coat/Top Coat Powder Coatings

• Breaks the limitations of traditional liquid paints, achieving high leveling, high gloss, and excellent UV aging resistance.

• The development of this powder coating was based on durability tests conducted in regions with extreme sunlight, with all test samples exposed to over five years of outdoor exposure.

• Suitable for body exterior panels, doors, hoods, and other exterior parts, providing long-lasting and brilliant exterior protection for vehicles.

5、Automotive Interior and Exterior Trim Powder Coatings

• Balances aesthetic diversity with durability, offering effects ranging from high gloss, matte, textures, to metallic finishes.

• Provides excellent weather resistance, chemical resistance, and fingerprint resistance.

Advantages of Our Powder Coatings in the Automotive Industry

1. Superior Performance and Durability

• Exceptional Weather and Chemical Resistance: Powder coatings protect vehicle bodies and components against UV rays, moisture, salt spray, gasoline, oils, acid rain, and road de-icing agents. They prevent fading, chalking, and corrosion, which is crucial for long-term appearance retention.

• Excellent Mechanical Properties: The coatings offer outstanding impact resistance, abrasion resistance, and flexibility (chip resistance), withstanding daily driving hazards like stone impacts, minor scratches, and part deformation.

• High Film Build Capability: Compared to liquid paints, powder coatings allow for a thicker protective layer (often over 150 microns) in a single application, providing a stronger physical barrier for parts demanding high corrosion protection, such as chassis, frames, wheels, and engine brackets.

2. High Economic and Production Efficiency

• High Material Utilization and Lower Cost: Overspray powder (exceeding 95%) can be collected and reused in powder coating systems, resulting in nearly zero waste. This significantly reduces material costs and waste disposal expenses.

• Simplified Process Flow: Powder coatings are often "single-coat" systems (e.g., primer-free powders), eliminating the need for separate primer or clear coats. This reduces curing steps and production line length, boosting production efficiency and capacity.

• Reduced Energy Consumption: Modern powder coatings with optimized curing temperatures and times (e.g., low-temperature curing technology) help lower baking energy requirements.

• Lower Operational Costs: There is no need to manage solvents, adjust viscosity, or frequently clean equipment as with liquid paints, reducing maintenance and operational complexity.

3. Outstanding Environmental and Safety Benefits

• Zero VOC Emissions: Powder coatings contain no volatile organic compounds, eliminating atmospheric pollution from painting booths and complying with increasingly stringent global environmental regulations (e.g., China's VOC control policies, EU REACH).

• No Hazardous Waste: Overspray powder is reclaimable, and no hazardous solvent waste is generated, minimizing disposal costs and environmental impact.

• Safer Working Environment: The absence of solvents eliminates risks of fire and explosion, as well as health hazards for workers from toxic solvent vapors, improving factory safety.

3. Innovative Aesthetics and Functional Design

• Diverse Aesthetic Effects: Powder coatings offer a wide range of colors (including metallics and vibrant shades), gloss levels (high-gloss to matte), and textures (e.g., sand, wrinkle, hammer tone), meeting diverse design needs for automotive interior and exterior parts.

• Special Functional Coatings: Functional powder coatings are available for specific components, such as:

• Electrical Insulation Coatings: For motors and battery components.

• High-Temperature Resistance Coatings: For engine compartments and exhaust system parts.

• Antimicrobial Coatings: For door handles and interior trim.

• Superior Edge Coverage: Advanced application techniques control the "Faraday cage effect," ensuring uniform and continuous coating coverage on sharp edges, welds, and corners, providing comprehensive corrosion protection.

4. Quality and Standard Certification: 

The production process and product quality management system comply with international standards, including ISO 9001、ISO14001, RoHS, and REACH, which ensures reliable performance and consistent quality for every batch.
