Abstract
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.
Claims25
An oxidation-protective coating composition for steel sheets comprising:
- (a) an aromatic organic solvent;
- (b) at least one source of aluminum;
- (c) a silazane;
- and
- (d) an organic synthesis catalyst.
A cured sheet steel paint coating, said coating comprising:
- a continuous network of iron-silicon oxides surrounding a matrix of silicon-aluminum oxides and globular particles of aluminum-silicon-iron oxides evenly distributed throughout said network.
A cured sheet steel paint coating, said coating comprising:
- a matrix of silicon-aluminum oxides with a network of iron oxide, globular iron-silicon oxide, and islands of aluminum-silicon-iron oxides substantially evenly distributed throughout said network.
