PROBLEM TO BE SOLVED: To provide a fin material for a heat exchanger on which coating excellent in not only a hydrophilic property and an antifouling property but also a metal-mold abrasion property is formed.SOLUTION: On the surface of a base material made of aluminium or aluminium alloy, there are formed a hydrophilic coat having, as a main component, polyoxyethylene chain provided in the deposition amount of 0.4 g/m-1.2 g/m; and an antifouling property coat made by applying and drying aqueous paint containing alumina particles, silica particles, and a polyoxyethylene system lubricant and provided on the hydrophilic coat in the deposition amount of 0.1 g/m-0.5 g/m. |
