Abstract
This disclosure is directed to a method of obtaining coated glass articles having a desired shading coefficient with the most economical thickness of coating composition applied thereto. The method taught is characterized by the following steps. A plurality of glass samples are coated with a selected coating composition. This coating operation is carried on the various glass samples in a manner such that the glass samples have different coating thicknesses of the selected coating composition. The thickness of the coating composition on each glass sample, along with the resulting shading coefficient, is measured. The correlation is made between the thickness of coating and the resulting shading coefficient. The correlation is one which will define two separate functions interconnected by a transition point. A first function (1) is one in which the shading coefficient decreases with increasing coating thickness. A second function (2) is one in which the shading coefficient remains relatively constant although the coating thickness is increasing. The method of this disclosure is concluded by coating commercial quantities of glass with the selected coating composition to a thickness which is plus or minus 10% of the coating thickness where the correlated relationship between the coating thickness and the shading coefficient goes through its transition point (3) from the first defined functional relationship (1) to the second defined functional relationship (2).
