Hydrophilic coatings for Air Conditioner

A water-based coating combination applied on the surface of aluminum foil,
which forms a layer with excellent hydrophilic effect after high-temperature
baking and curing, including primer coating and top coating. Aluminum foil
coated with hydrophilic coating is called "air conditioning hydrophilic
aluminum foil", mainly used in air conditioning heat exchanger.
In the core structure of modern air conditioning systems, heat exchangers play
a critical role in maintaining energy efficiency and system reliability. The
aluminum fins of these heat exchangers are typically treated with hydrophilic
coatings that optimize water management, improve heat exchange performance, and
protect against corrosion — ensuring long-term, trouble-free operation.
Main functions
Anti-Corrosion Protection
Effectively shields aluminum fins against chemical, environmental, and
electrochemical corrosion — especially critical in humid, coastal, or marine
climates.
Improved Heat Exchange Efficiency
Promotes rapid water spreading and drainage, reducing the risk of water droplet
accumulation and delayed evaporation. This enhances heat transfer efficiency
and helps maintain optimal system performance.
