Abstract
The present disclosure provides a solution composition having excellent acid corrosion resistance and adhesion to a steel sheet, a steel sheet surface-treated using the solution composition, and a method for manufacturing the steel sheet. Specifically, the present disclosure provides a solution composition for treating a surface of a steel sheet, the solution composition containing colloidal silica, alkoxy silane, a solvent, an acidity regulator, an acrylate-based monomer, an adhesion improver including a backbone formed of siloxane bonds, and a metal chelate curing agent, a steel sheet surface-treated using the solution composition, and a method for manufacturing the steel sheet.
