PVDF Color Coated Aluminum Coil

1. What is PVDF Color Coated Aluminum Coil ?

Polyvinylidene fluoride (PVDF) coatings are a factory-applied, resin-based coating system on aluminum coil or aluminum sheets,  so that the aluminum materials can resistant to UV rays and keeps surface color looking brand new for a long time. 

2. What are the usage of PVDF Color Coated Aluminum Coil ?

PVDF coating aluminum coil and sheets are widely used in many places, beacuse aluminum coil coated with PVDF, it can resistant to UV rays, so the building wall panel decorated by composite aluminum panels usually coated PVDF coating can keep color at least 15 years. 

3. What is the structure of PVDF Color Coated Aluminum Coil?

PVDF coated aluminum coil sheet can be easily divided into surface coating paint and primer due to different processing and usage purposes. According to the raw materials of the coating paint, it can be further divided into polyester (PE) coated aluminum coil and fluorocarbon (PVDF) coated aluminum coil. Of course, there are also cases where one side is coated with fluorocarbon and the other side is coated with polyester, or even both sides are coated with fluorocarbon compounds.

The coating thickness of pvdf color coated aluminum coil sheet can be divided into double coating (25μm-28μm), and triple coating (35μm-40μm).

Advantages of PVDF Color Coated Aluminum Coil Sheet: 

1. Durability: PVDF coating is highly durable and can withstand harsh weather conditions, including extreme temperatures, UV radiation, and moisture. This characteristic makes it ideal for use in outdoor applications, such as roofing, cladding, and facades.

2. Resistance to fading: PVDF coating is resistant to fading, ensuring that the aluminum coil maintains its color and appearance over time. This characteristic makes it a preferred choice for applications where color retention is crucial, such as building exteriors and signage.

3. Chemical resistance: PVDF coating is resistant to many chemicals, including acids, alkalis, and solvents. This characteristic makes it suitable for use in industrial applications, such as chemical processing plants, where the environment can be highly corrosive.

4. Easy to clean: PVDF coating is easy to clean, requiring only mild soap and water to maintain its appearance. This characteristic makes it suitable for use in areas where hygiene is important, such as hospitals, laboratories, and food processing facilities.

Application of PVDF Color Coated Aluminum Coil:

PVDF coated aluminum coil sheet are mainl used for exterior building facades:  including wall panels, cladding panels, curtain walls, roofing sheets, louvers, and canopies. Its durability, weather resistance, and aesthetic appeal make it ideal for creating stunning and long-lasting structures materials.

Frequently Asked Questions About PVDF Color Coated Aluminum Coil： 

Q1: What is the difference between PVDF coated aluminum coil and PE coated aluminum coil?

A1: PVDF coated aluminum coil provides superior durability, UV resistance, and weather performance compared to PE coated aluminum coil. PVDF coatings are recommended for exterior building applications, while PE coatings are more suitable for interior decoration.

Q2: Why is PVDF aluminum coil preferred for exterior building facades?

A2: PVDF aluminum coil offers exceptional resistance to sunlight, rain, humidity, and temperature fluctuations, making it ideal for exterior wall panels, curtain walls, and building facade systems.
