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 coatingis 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.
Extended Service Life
By preventing early corrosion and reducing frost buildup, hydrophilic coatings significantly extend the operational lifespan of air conditioner units, reducing maintenance and replacement costs.
Coil coatingsare metal surface treatment technologies designed specifically for home appliances and construction. These coatings are pre-applied to metal sheets before they are formed, and then cured by baking to form a protective film.
