The surface of hydrophilic coated aluminum foil has strong hydrophilicity. When used in air conditioners, it can optimize the ventilation effect of the heat exchanger, thereby increasing the heat exchange rate by 5%. In addition, hydrophilic coated aluminum foil also has other advantages such as anti-corrosion, anti-mold, and no odor. It is mainly used in the production of heat exchanger fins, such as air-conditioning condensers and evaporators, refrigerator frost-free evaporators/fin-type evaporators, Commercial refrigerator condenser and evaporator, automobile air conditioner condenser and evaporator, etc.
Hydrophilic aluminum foil is a deep-processed aluminum foil product that is coated with anti-corrosion coating and hydrophilic coating on plain aluminum foil. Aluminum foil made by coating an air-conditioning aluminum foil with a thickness of about 0.1mm with an anti-corrosion coating and a hydrophilic coating, and drying it in a drying oven. Hydrophilic foils can be surface-coated, often with blue and gold finishes.

Advantages of hydrophilic coated aluminum foil:
1. Excellent hydrophilicity and corrosion resistance;
2. Good formability and no wear on the mold;
3. Extremely strong resistance to stamping oil, solvent resistance and heat resistance;
4. The air flow resistance is small, and the heat exchange rate can generally be increased by 10%-15%.
