AIRFIN® is lacquered foil to be used for the production of fins for heat exchangers with a high corrosion resistance. Its main advantages are: • Highly cured polymers: AIRFIN´s are at least 300% more corrosion resistant than bare aluminium. • Very good finishing, high thermal conductivity, good drawability and low density. • Collars height up to 12 mm could be obtained. • AIRFIN® finishing have been developed to have highest possible resistance to scratches. • Studies performed by specialized independent organisms demonstrate that AIRFIN® does not favour the growth of micro-organisms. • AIRFIN® 300: ensures their properties AIRFIN® without fear of the aging by UV. The chemical decomposition of many polymers is catalyzed by the UV rays, all their properties unaffected by other side-reactions. • AIRFIN® 500: Demand the quality AIRFIN® 500 to strengthen the corrosion resistance and ensure a lengthening of the life of its exchanger. Can adapt to any environment. For all range of products an alternative with a pre-treatment coating is available that increases the corrosion resistance of the standard products. AIRFIN® includes the following range of products: • AIRFIN® 100: is an excellent solution of coating against corrosion of the fin. This product offers the desired protection in a wide range of colours. • Heat exchangers for food industry. • Heating and air conditioning systems for buildings • Heat exchangers for cars, ships and airplanes
