PURPOSE:To obtain the title paint which has excellent storage stability and an excellent effect of preventing the corrosion of a metal surface, by incorporating a specified amount of zinc chloride and zinc dust into a binder comprising an alkyl silicate having no silanol group in its molecule. CONSTITUTION:The title paint is obtained by mixing as its principal constituents an alkyl silicate (A) having no silanol group in its molecule (e.g., orthoethyl silicate or orthomethyl silicate), zinc chloride (B), and zinc dust (C) in such proportions that the amount of the component B is 30-120pts.wt. based on 100pts.wt. silica (on an SiO2 basis) contained in the component A. In addition, an organic solvent, an extender pigment, etc., can be incorporated into this paint to improve the applicability, the characteristics of a coating film, etc. The coating material thus obtained is of a single package type, has excellent storage stability, and can be dried in a short time.
