In this paper a water based organo-inorganic dispersion as coating material has been prepared in the system polymer emulsion – inorganic filler – additive. The structure, topography, morphology and thermal stability of the film coating have been determined by SEM and TG analysis. The properties of the dried film like hardness, scratch abrasion, blocking resistance, elasticity, flexibility, dielectrical rigidity and optical aspect have been determined and compared with those of the conventional acrylic coating.
