There are provided a beat-resistance treated metal sheet with excellent scratch resistance and corrosion resistance, and a process for the manufacture and an aqueous silicate paint with which the heat-resistance metal sheet can be obtained. On a metal or plated metal sheet, an aqueous silicate paint is applied and dried in an amount of 0.1- 3.0 g/m2 in terms of dry weight to form the silicate film, wherein the aqueous silicate paint is composed of an alkali metal silicate, a colloidal silica, a silane coupling agent, a polyolefin wax dispersion and water, and the content of the alkali metal is 10 to 20% by weight in terms of solid content. |
