Abstract
Liquid compositions suitable for providing silica-based coating films on to various substrate surfaces are prepared by the reaction of an alkoxy-containing silane, a lower carboxylic acid and an alcohol in the presence of a reaction accelerator which is an organic acid different from the above mentioned lower carboxylic acid. The reaction proceeds very smoothly even in the absence of any halogen-containing compounds, and the resultant liquid coating compositions are free from the problem of corrosion due to the presence of a halogen-containing ingredient.
