A novel fluorocarbon polymer coating composition in which glass fibers are successfully dispersed to add enhanced scratch and wear resistances to the superior properties inherent to the fluorocarbon polymer. The glass fibers are firstly sized with a solution of a titanate coupling agent and subsequently sized with a solution of a silane coupling agent. With this composite sizing treatment, the glass fibers can have greatly improved wettability or compatibility with the fluorocarbon polymer coating composition so that they can be substantially randomly dispersed in the coating composition, whereby the fluorocarbon polymer coating can have the combined superior properties resulting from the use of the fluorocarbon polymer and the incorporation of the glass fibers.

A coating process for aluminum-zinc alloy plated sheet steel provides an article having a surface of improved formability and enhanced corrosion resistance; appearance and paintability. The coating is applied in aqueous form at a prescribed pH value and dried. The aqueous coating contains a water dispersible or water soluble resin and hexavalent chromium in desired proportions.
