Abstract

A process is described for sealing anodic coatings on aluminum and the alloys of aluminum while simultaneously impregnating the anodic coating with organic resin during the sealing operation, thereby providing a protective coating to the anodized aluminum which, among other things has superior corrosion resistant characteristics. A specified water-borne resin coating material possessing excellent stability at temperatures in excess of 170.degree.F is used to convert the unsealed anodic coating to the monohydrate/trihydrate form of aluminum oxide during the sealing step of an otherwise conventional aluminum anodizing process. Subsequently, the sealed anodic film is cured at temperatures up to 500.degree.F. This process provides a total protection system having characteristics superior to separately sealed and organically primed aluminum obtained through conventional processing. [CA1111368A]
