Beschreibung
Zusammenfassung:	Disclosed in the present invention is a surface treatment agent for use on enamel steel or a part, an aqueous solution thereof comprising the following solid components in parts by mass: 15 to 55 parts of an aqueous polymer resin A; 32 to 58 parts of an organosilane coupling agent B having at least one epoxy functional group, wherein the ratio of parts by mass of the organosilane coupling agent B to the aqueous polymer resin A is 0.6 to 2.2; 0.2 to 3 parts of a polyol C containing at least three hydroxyl groups; 0.05 to 2 parts by mass of a molybdenum compound D, in terms of elemental molybdenum; 0.1 to 1 parts by mass of a phosphorus compound E, in terms of elemental phosphorus; 0.1 to 1 parts by mass of a zirconium compound F, in terms of elemental zirconium; and 0.5 to 8 parts of a metal salt or an organometallic compound G which promotes adhesion. The enamel steel coated with the surface treatment agent has excellent processability, and good resistance to various chemical media. The present invention effectively improves the surface adhesion between a ceramic glaze layer and a steel substrate, as well as the surface quality of a final enamel product.
