An insoluble silica based film is formed by placing an ammonium compound and an alcohol as a plasticizing agent in an aqueous solution and blending the aqueous solution with a sodium silicate. The mixture is allowed to condense which produces the insoluble silica-based film. The film is used as a binder, and has particular application as a vehicle in a paint. The invention also describes a method for preparing an insoluble silica-based binder.
