PVDF Aluminum Composite Panel
Polyester-coated aluminium composite panels use a single- or multi-layer roller coating (PE) process to deliver uniform colour, selectable gloss levels, and reliable adhesion at an economical cost. They offer good formability and surface smoothness for a wide range of architectural applications—especially interiors and moderate-climate exteriors—making them a practical choice when balanced performance and budget are required.

Characteristics of PVDF Color-Coated Aluminum Composite Panels
Alucobang PVDF color-coated aluminum composite panels combine premium fluorocarbon coating technology with high-strength aluminum and a durable core layer. They offer exceptional weather resistance, superior color stability, and long-lasting surface performance even in harsh outdoor environments. With strong adhesion, corrosion resistance, and anti-pollution properties, they are ideal for modern architectural façades, curtain walls, and exterior decorative applications that require both aesthetic appeal and long-term durability.
Excellent UV Resistance
The PVDF fluorocarbon coating provides outstanding resistance to ultraviolet radiation, effectively preventing surface degradation and fading. This ensures long-lasting color brilliance even under continuous sun exposure.
High Chemical and Weather Resistance
PVDF-coated aluminum composite panels exhibit strong resistance to acid, alkali, and industrial pollutants. They maintain excellent mechanical integrity and color stability even in high-humidity, coastal, or industrial environments, ensuring exceptional weatherproof performance.
Long-Term Outdoor Durability
After 15–20 years of outdoor exposure to sun and rain, the gloss retention rate and color variation of PVDF panels still meet the AAMA 2605 standard, ensuring reliable and enduring performance for exterior architectural applications.
Application Fields of PVDF Aluminum Composite Panels
Alucobang PVDF fluorocarbon-coated aluminum composite panels are widely used in modern architectural façades, public landmarks, and large-scale commercial complexes. Their superior weather resistance, long-lasting gloss, and vibrant color retention make them ideal for high-end, durable exterior decoration projects.
Office Buildings
Used for sleek and elegant corporate façades, PVDF panels provide a high-end metallic finish with strong UV and corrosion resistance, ensuring long-lasting aesthetic appeal and professional appearance.
Stadiums and Gymnasiums
PVDF-coated panels are ideal for large-span public venues that require durable, lightweight, and weatherproof materials, maintaining their vivid color and surface integrity over time.
Exhibition Centers
For exhibition centers and convention halls, PVDF aluminum composite panels create modern, clean, and impressive visual effects while ensuring high corrosion and dirt resistance for large public spaces.
Exterior Curtain Walls of High-End Buildings
PVDF fluorocarbon-coated ACPs are the top choice for luxury residences and landmark towers, providing unmatched durability, surface flatness, and long-term color consistency.
With their combination of superior weatherability, elegant appearance, and lasting strength, Alucobang PVDF-coated aluminum composite panels are the preferred solution for modern architecture that demands both performance and design excellence.
How to Select PVDF Aluminum Composite Panels
Key Selection Standards
- PVDF resin content ≥ 70% — ensures coating purity and weather resistance.
- Inorganic pigments are preferred for stable color and UV durability.
- Coating thickness ≥ 25 μm — meets outdoor exposure requirements.
- Surface gloss ≤ 40 GU — provides a soft, elegant matte appearance.
Supplementary Notes
- μm (Micrometer): 1 μm = 0.001 mm. A 25 μm coating ensures long-term surface durability and corrosion resistance.
- Gloss Units (GU): Below 40 GU is considered matte or semi-matte, effectively reducing glare on large façades.
