TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The coating formulation comprises: at least 60 wt.% or at least 70 wt.% of the solvent; less than 5 wt.% of at least one solvent having a boiling point of less than 125, 150, 170 or 185 degrees C at atmospheric pressure; less than 10 wt.%, preferably less than 5 wt.% of silicon dioxide solids concentration; a tetraalkoxysilane residue; and a pH of less than 5. The coating formulation further comprises: at least one polyol; and at least one catalyst. Preferred Components: The catalyst comprises a base catalyst. Preferred Method: The applying step comprises roller coating the coating formulation onto at least a portion of an optically transparent substrate. The heating step comprises heating the coating formulation at at least 200 degrees C, preferably at 200-400 degrees C. The heating step further comprises heating the coating formulation at at least 400 degrees C, preferably at 400-750 degrees C. The method for producing the coating formulation further comprises: maintaining the pH of the coating formulation for a sufficient period of time at a sufficient temperature to form polymer particles and then reducing the pH of the coating formulation to less than 5; and adding an additional amount of solvent having a boiling point of at least 125 degrees C.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The alkoxysilane residue comprises at least a second alkoxysilane residue comprising trialkoxysilane residues, dialkoxysilane residues and/or monoalkoxysilane residues. The solvent comprises at least one alkylene glycol. The solvent is at least one of ethylene glycol, propylene glycol, di(ethylene)glycol, tri(ethylene)glycol, tetra(ethylene) glycol, penta(ethylene)glycol, di(propylene)glycol, hexa(ethylene)glycol or their ethers. The solvent has a boiling point of at least 150, 170 or 185 degrees C.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The polyol comprises at least one polyethylene or polycaprolactone polyol. EXAMPLE - Di(propyleneglycol)methyl ether (640.9 g having a boiling point of 190 degrees C, at a vapor pressure of 0.37 mBar), tetraethoxysilane (80.62 g) and methyltriethoxysilane (38.89 g) were added to a round-bottom flask (2 l) with a mechanical stirrer. As the components were mixed vigorously with the stirrer, a mixture of 1M tetrabutylammonium hydroxide (6.242 g) in methanol and deionized water (200.243 g) was gradually added (over 30 seconds) to the reaction mixture. After stirring the reaction mixture for 24 hours at room temperature, 35% nitric acid (3.12 g) was added and the resulting mixture was stirred for an additional 15 minutes. The mixture (5 g) was diluted with di(propyleneglycol)methyl ether (5 g) to form a coating formulation.
