PERMANENT WATER WETTABLE PRODUCT AND PRODUCTION THEREOF

摘要

The surfaces of articles of manufacture fabricated from aluminum and other materials which are not permanently water wettable are rendered permanently water wettable by coating the surface with a continuous film containing colloidal alumina of a water soluble form of basic film forming polymer which is curable to water insolubility; curing the polymer to water insolubility; and hydrolyzing the surface portion only of the cured polymer.
