Coating fluid for sio2 film formation

Abstract

Abstract PURPOSE:To provide a coating fluid for SiO2 film formation excellent in storage stability, workability, etc., by incorporating as a principal component hydroxysilane (oligomer) given by the reaction of tetraalkoxysilane with water in the presence of a phosphate in an org. solvent. CONSTITUTION:Tetraalkoxysilane (e.g., tetramethoxysilane, tetraisopropoxysilane) is reacted with water in the presence of a phosphate of formula I or II (wherein R is 1-6C alkyl, aryl) etc. in an org. solvent such as methanol, propylene glycol, or acetone. The resulting hydroxysilane and/or oligomers thereof, as principal components, and, if necessary, org. solvents, surfactants, etc. are blended to give the intended coating fluid for SiO2 film formation. Said coating film can be applied onto substrates such as glass, metallic materials or by roll-coating, offset printing, etc.
