ABSTRACT A coating suspension for coating a substrate including negatively charged fine particles, water, a negative charge precursor, a defoaming agent, a surface active agent, an insolubilizing agent, a plasticizer, and two water-soluble binders is provided. In a preferred embodiment the fine particles are fine particle-size silica. There is also provided a method for coating a substrate with fine particles having a negative electrical charge. The method includes forming a coating suspension including the fine particles, water, a negative charge precursor, a defoaming agent, a surface active agent, an insolubilizing agent, a plasticizer, and two water-soluble binders; applying the coating suspension to the surface of the substrate to form a coated substrate; and heating the coated substrate to cure the coating and remove the water from the suspension. The coating formed is insoluble in water and water based media.
