Steel sheet coating compositions in which polymeric resin or ceramic properties are produced by admixing an aluminum coordinate complex and an anhydrous, encapsulated, aluminum particle paste, a polysilazane as a source of silicon, an organic solvent, an organic synthesis catalyst, and optionally a non-metallic, non-ionic, low-nucleophilic base. The admixed coating is applied to sheet steel prior to hot-stamping in order to inhibit surface formation of iron oxides and to improve steel sheet surface characteristics.
