Abstract
Steel sheet coating compositions or polymeric resin or ceramic properties are produced by admixing an aluminum coordinate complex and an aluminum resin, a polysilazane as a source of silicon, an organic solvent, an organic synthesis catalyst, and a non-metallic, non-ionic, low-nucleophilic base. The admixed coating is applied to sheet steel prior to hot-stamping in order to inhibit formation of iron oxides and to improve steel sheet surface characteristics.
Claims1
A steel sheet for hot-stamping, comprising said steel sheet having at least one surface coated by a composition comprising:
- (a) an aromatic organic solvent;
- (b) a source of aluminum;
- (c) a silazane;
- and
- (d) an organic synthesis catalyst.
