Production process of 8079 color coated aluminum foil
1. Aluminum Foil Base Material Selection
First, high-quality aluminum alloys (such as 8079 aluminum foil) are selected and rolled into thin sheets to achieve the required thickness. The focus during this stage is on the flatness, thickness uniformity, and surface quality of the aluminum foil.
2. Surface Pre-Treatment
To ensure that the coating adheres well to the aluminum foil, the surface must be pre-treated. Common surface treatment methods include:
- Cleaning: Removing oils, dust, and other impurities from the aluminum foil surface.
- Chemical Etching: Using chemical reactions to roughen the surface of the aluminum foil, increasing its surface roughness and improving coating adhesion.
- Phosphating: Forming a phosphate film on the surface of the aluminum foil, further enhancing the adhesion of the coating.
3. Coating Application
Applying the coating to the aluminum foil surface is the core step in the production of color coated aluminum foil. The coating material is chosen according to the specific application requirements, with common coatings including PE (Polyester) and PVDF (Fluorocarbon) coatings. The coating methods generally include:
- Roll Coating: Applying the coating evenly across the surface of the aluminum foil, suitable for mass production.
- Spray Coating: Using a spray gun to apply the coating to the surface of the aluminum foil, suitable for fine craftsmanship and complex shapes.
4. Baking and Curing
After the coating is applied, the aluminum foil needs to be baked in an oven at high temperatures. Under these high temperatures, a chemical reaction occurs between the coating and the aluminum foil surface, forming a strong protective film. The baking temperature and time vary depending on the coating material.
- PE Coating: Typically baked at around 150°C for 10-15 minutes.
- PVDF Coating: Requires higher temperatures, usually around 200°C, with a baking time of 20 minutes.
5. Cooling and Cutting
After baking, the color-coated aluminum foil must cool naturally. Once the temperature lowers, it is slit into narrower widths as required. We can cut the aluminum foil into different widths and coil weights according to customer needs.
Purchasing guide for 8079 color coated aluminum foil
1. Alloy Selection
Common alloys used for building insulation and roof waterproofing include 8011, 8079, 1050, and 1200. Different alloys have distinct characteristics and should be chosen based on the specific application needs. For example, 8079 alloy is suitable for applications requiring higher strength and moisture resistance.
2. Coating Types
Color-coated aluminum foil coatings are divided into PE and PVDF types. PE is suitable for indoor use, offering good weatherability and decorative effects. On the other hand, PVDF is ideal for outdoor environments, with stronger UV resistance, acid-base resistance, and corrosion resistance. Choosing the right coating ensures long-term performance of the aluminum foil.
3. Key Indicators to Consider When Purchasing

4. Environmental Adaptability
- Temperature and Humidity: Different coatings of color-coated aluminum foil have varying adaptability to temperature and humidity. Choose the appropriate coating based on the application environment.
- UV Exposure: Applications exposed to sunlight for extended periods require materials with strong UV resistance, such as PVDF coating.
- Acid-Base Environments: For applications like food packaging and chemical packaging, consider the material's acid-base resistance to ensure that it will not degrade due to chemical exposure.
5. Quality Control and Packaging
To ensure safety during transportation, 8079 color coated aluminum foil is typically packaged according to export standards. Packaging methods include packing with wooden pallets or in roll form. The packaging material needs to be moisture-resistant, impact-resistant, and ensure that the surface of the aluminum foil remains undamaged. Packaging sizes and methods can be customized according to customer requirements.
