| titleOfInvention | Surface treatment agent for zinc-based plated steel sheet |
| abstract | The present invention provides a surface treatment agent for zinc-based plated steel sheets, which has excellent film-forming properties and excellent corrosion resistance, chemical resistance, and weather resistance of the coating film. The surface treatment agent for zinc-based plated steel sheets includes: a zirconium compound (A), a chelating agent (B) having one or more hydroxyl groups in one molecule, and an organic resin (C) having a carboxyl group (c1); wherein , Zirconium compound (A), in terms of zirconium element, the content in the surface treatment agent for zinc-based plated steel sheet is in the range of 200 to 10,000 mass ppm, and the zirconium element (Zr) derived from the zirconium compound (A) and The molar ratio of the chelating agent (B) is in the range of (Zr)/(B)=4-100, the acid value of the organic resin (C) is in the range of 10-30 mgKOH/g, and the carboxyl group (c1) is in the range of The molar ratio of the chelating agent (B) is in the range of (c1)/(B)=30-1000. |
