(57) [Problem] To provide an inorganic coating product excellent in interlayer adhesion and weather resistance. SOLUTION: This is an inorganic coating product in which an inorganic coating layer is disposed on the outermost layer of the substrate surface via a primer layer, wherein the primer layer has (a) two or more epoxy groups in one molecule. Epoxy compound, (b) 2 in one molecule An organosilicon compound having at least one mercapto group and at least two alkoxy groups, (c) an organosilicon compound having at least one amino group and at least two alkoxy groups in one molecule, and (d) an organic solvent It is assumed that a primer containing the above component is applied, and the inorganic coating layer is applied with a silicon alkoxide-based coating agent mixed with fine-particle zinc oxide as an ultraviolet absorber. |
