Process for rendering surfaces permanently water wettable and novel products thus-produced

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.
