Abstract
An acidic aqueous coating composition comprising dissolved phosphate, dissolved aluminum, dissolved dichromate, inorganic colloidal particles and a water miscible organic component including an effective film-forming amount of a water miscible material comprising an ether of a polypropylene glycol, and preferably including also another glycol material, for example, a mono-ethylene glycol material or a mono-propylene glycol material, for use in forming a glaze coating, or a base coating when said composition includes also a particulate material.
