Abstract
PURPOSE: To obtain the titled coating solution having productivity and stability, providing an improved film, by hydrolyzing a specific silicon compound with an acidic aqueous solution, dhydrating the prepared compound to give a specific hydrolyzate.
CONSTITUTION: A silicon compound, silane halide (e.g., silicon tetrachloride, etc.) and/or alkoxysilane (e.g., tetramethoxysilane, etc.), is dissolved in a phase solvent, e.g., alcohol, blended with ≥ mole based on silicon compound of an acidic aqueous solution (an aqueous solution of hydrochloric acid), and hydrolyzed preferably at 30W60°C in an acidic pH range of ≤4. An inorganic electrolyte, etc. is added to the hydrolyzed solution, which is subjected to salting-out and dehydrated, to give a hydrolyzate having a molar ratio of water/silicon oxide of ≤5. This hydrolyzate is blended with ethylene glycol, etc., to give the desired coating solution.
USE: For coating the solid surface of glass, ceramic, metal, etc.
