Precoated Finstock

Precoated finstock is a kind of aluminum foil material treated with a special coating, which has high corrosion resistance and thermal conductivity. This kind of aluminum foil fin stock is usually used in the field of refrigeration and air conditioning as materials for heat exchangers, evaporators, condensers, etc. It has the advantages of high efficiency of heat transfer, corrosion resistance and light weight.


The production process of pre coated fin stock aluminum foil mainly includes aluminum foil rolling, coating application and curing treatment. Coating materials are usually selected from organic or inorganic materials with good corrosion resistance, high temperature resistance and insulating properties, such as polyester, silicone and polyimide. During the production process, the coating thickness, uniformity, adhesion and degree of curing need to be strictly controlled to ensure the performance and quality of aluminum fin stock foil with coating.

The precoated finstock with hydrophilic coating are usually made of materials with good thermal conductivity, such as aluminum and copper, and coated with a hydrophilic coating. This coating can be some organic or inorganic materials with hydrophilic properties, such as titanium dioxide, silicon oxide, polymers, and so on. These materials can interact with the water molecules, making it easier for the water molecules to attach to the surface of the fins, thus improving the heat transfer efficiency. The finstock with a hydrophilic coating has several advantages. First, it improves the heat transfer efficiency and cooling effect of the equipment, reducing energy consumption and equipment operating costs. Secondly, due to its hydrophilic properties, it prevents the formation of scale, thereby extending the service life of the equipment. In addition, fins with hydrophilic coating have the advantages of anti-corrosion, easy cleaning and maintenance.


Compared with ordinary aluminum foil, precoated finstock aluminum foil has better corrosion resistance and thermal conductivity, which can improve the heat transfer efficiency and extend the service life of the air conditioner equipment. In addition, pre coated aluminum foil fin stock is aesthetically pleasing and easy to clean and maintain. As a result, pre coated aluminum foils are widely used in refrigeration and air conditioning applications.
