FIN MATERIAL, FIN MATERIAL FOR HEAT EXCHANGERS, AND AIR CONDITIONERS

摘要

A fin material which comprises an aluminum substrate, an oxide film formed on the substrate, and an outermost hydrophilic membrane formed on the oxide film by using a hydrophilic composition, characterized in that the hydrophilic composition contains a hydrophilic polymer in an amount of 80mass% or above of the solid matter and the hydrophilic polymer has a specific structure bearing both a hydrophilic group and a reactive group.
