Abstract

An inorganic coating composition which is incombustible, water resistant and durable comprises an aqueous dispersion of colloidal silica (A), laminar aluminum oxide and/or a luminum hydroxide (B), water-soluble amino-alcohol (C), and one or more members selected from the group consisting of metallic zinc, zinc compounds and oxides and hydroxides of alkaline earth metals (D). The molar ratios of said component (C) to component (A) and said component (D) to component (A) are in the range of 0.01/1.0 to 1.0/1.0 and the weight ratio of said colloidal silica to colloidal silica plus water in said coating composition is not less than 0.1.
