More Information
Summary:A hydrophilic surface treatment chemicals comprising, on a solid basis, (a) 1-10 parts by weight of at least partially saponified polyvinyl acetate having a saponification degree of 45 or more and a polymerization degree of 100-600, (b) 0.3-15 parts by weight of water-soluble nylon, and (c) 0.1-5 parts by weight of a water-soluble amino resin, a weight ratio of the component (b) to the total of the components (a) and (c), (b)/[(a)+(c)], being in the range of 1 - 1/4, and a weight ratio of the component (a) to the component (c), (a)/(c), being in the range of 1/0.05 -1/0.5. The hydrophilic surface treatment bath is prepared by properly diluting the chemicals for surface-treating aluminum members. A method of surface-treating aluminum or its alloy for imparting hydrophylic nature thereto is also disclosed.
