Chalco Aluminum Coat lacquered 3102 8011 aluminum coil strip fin stock for heat exchanger have two types, one is normal hydrophilic 3102 8011 aluminum coil strip (blue),and the other is high corrosion of hydrophilic aluminium foil( Golden).

Normal hydrophilic aluminum foil coated in blue color, this lacquered 3102 8011 aluminum coil strip 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 3102 8011 aluminum coil strip 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 coil strip

High corrosion of hydrophilic aluminium coil strip

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.
