Abstract
A new coating composition, coated article and method are disclosed herein dealing with the preparation of coated surfaces which are useful, for example, in glass molding wherein a relatively lubricious, abrasion resistant surface is desired under conditions of high operating temperatures. The coating composition in its most basic aspect involves a dispersion of an aluminum phosphate and a very fine particle size pigment material together with other materials including novel dispersion stabilizing ingredients and a special water dispersible resinous film-modifying agent.
