Lacquered Aluminium Foil for Heat Exchanger Fin

Signi Coat lacquered aluminium foil fin stock for heat exchanger have two types, one is normal hydrophilic aluminium foil (blue),and the other is high corrosion of hydrophilic aluminium foil( Golden).
Normal hydrophilic aluminum foil coated in blue color, this lacquered aluminium foil makes the condensated water drop to become a layer avoiding the feasibility of ice bridges. It allows to produce smaller equipment.
High corrosion of hydrophilic aluminium foil coated in golden color, is an excellent solution of coating against corrosion of the fin. Expoxy resins based on highly specific to this application, provides the desired protection in a wide range of colours.
  Normal hydrophilic aluminum foil High corrosion of hydrophilic aluminium foil
Advantages 1. Very good finishing, high thermal conductivity, good drawability and low density.
2. Collars height up to 12mm could be obtained(depending of the thickness and haracteristics of metal).
3. Studies performed by specialized in independent organisms demonstrate that does not favor the growth of micro-organisms.
4. With high hydrophilic preperties its is the best choosing for standard environments.
5. It is also possible to incorporate our pre-treatment systems that improve the protection against corrosion and the lacquer adherence over the aluminium surface.
1. The polymers with high degree of reticulation aluminium lining prevent aggressive agents come in touch with the metal, they themselves being ver resistant to corrosion, the fins are at least 300% more resistant to corrosion than bare aluminum.
2. Very good finishing, high thermal conductivity, good drawability and low density.
3. Collars height up to 12mm could be obtained.
4. Finishing have been developed to have highest possible resistance to scratches.
5. Studies performed by specialized independent organisms demonstrate that this foil does not favour the growth of micro organisms.
6. It is also possible to incorporate our pre-treatment systems that improve the protection against corrosion and the lacquer adherence over the aluminium surface.
Applications Signi coat supplies its product normal hydrophilic aluminum foil, can be used for the development of the following applications:
 
Heat exchangers for food industry.
Heating and air conditioning systems for buildings.
Heat exchangers for car, ship and airplanes.
Signi coat supplies high corrosion of hydrophilic aluminium foil, can be used for high corrosion resistance of the following applications:
 
Heat exchangers for food industry.
Heating and air conditioning systems for buildings.
