PVDF Color Coated Aluminium Coil Weather-Resistant RAL Color For Outdoor Wall Cladding Applications

1. What is Color Coated Aluminum Coil?

Color coated aluminum coil is a high-quality, pre-painted aluminum product that is produced through a continuous coating process. This process involves applying one or more layers of organic paint to aluminum coils, which are then baked and cured to form a durable, colorful, and protective coating. This type of aluminum coil is widely used in various industries due to its aesthetic appeal, lightweight, and excellent corrosion resistance.

2. Detailed Description

1. Base Material:

- The base material for color coated aluminum coil is typically pure aluminum or aluminum alloy, which is known for its lightweight and excellent formability. The most commonly used grades include AA1100, AA3003, and AA3004.

2. Coating Process:

- Surface Pretreatment: The aluminum coils undergo surface pretreatment, which includes cleaning, degreasing, and chemical conversion to ensure good adhesion of the coating.

- Primer Coating: A primer layer is applied to enhance adhesion and provide additional corrosion resistance.

- Top Coating: The top coat, which provides the final color and aesthetic finish, is applied. This layer also contributes to the overall durability and resistance to environmental factors.

- Baking and Curing: The coated aluminum is then baked and cured in an oven to ensure the coating is properly bonded and durable.

3. Types of Coatings:

- Polyester (PE): Offers good adhesion, flexibility, and resistance to UV rays. It is cost-effective and suitable for general use.

- Silicon Modified Polyester (SMP): Provides better hardness, abrasion resistance, and heat resistance compared to PE. It also offers good color retention and gloss.

- High Durability Polyester (HDP): Known for excellent color retention, UV resistance, and overall durability. It is ideal for outdoor applications.

- Polyvinylidene Fluoride (PVDF): Provides superior color retention, UV resistance, and durability. It is highly resistant to solvents and chemicals, making it suitable for harsh environments.

5. Characteristics

Color-coated aluminum sheets in coils are known for their long service life, light weight, excellent surface finish, and high recycling value. These properties provide significant economic benefits, meeting the urgent demands of modern society for economic growth and environmental protection.

6. Export packaging

typically includes several types to ensure safe and secure transportation. Here are the common packaging methods:

1. Wooden Pallets:

- Coils are placed on sturdy wooden pallets.

- The pallets provide a stable base for handling and shipping.

- Often used for loading multiple coils together.

2. Wooden Cases or Crates:

- Coils are enclosed in wooden cases or crates.

- Provides full protection against physical damage during transportation.

- Suitable for long-distance and international shipping.

3. Steel Strapping:

- Coils are secured with steel straps.

- Ensures the coils are tightly bound to prevent shifting.

- Commonly used in combination with other packaging methods.

4. Plastic Film Wrapping:

- Coils are wrapped in plastic film.

- Protects against moisture, dust, and other environmental factors.

- Often used as an additional layer of protection within wooden cases or on pallets.

5. Edge Protectors:

- Protects the edges of the coils from damage.

- Can be made of plastic, cardboard, or metal.

- Typically used in combination with strapping and film wrapping.

6. Vapor Corrosion Inhibitor (VCI) Paper:

- Coils are wrapped in VCI paper.

- Provides additional protection against corrosion.

- Particularly useful for sea shipments where moisture is a concern.
