ABSTRACT:
A hydrophilic surface-treating aqueous solution and a hydrophilic surface-treating method are provided to form a film which can maintain its hydrophilicity. The hydrophilic surface-treating aqueous solution contains as main components polyglutamic acid, basic compound, and aqueous resin if necessary. This surface-treating solution and method enable the forming of a film on the surface of aluminum series metals which are used for aluminum fins of heat exchangers, and confer the film's anticorrosion properties, superior hydrophilicity and high hydrophilic permanency, while remarkably suppressing an offensive odor.
