ANTI-RUST TREATMENT SOLUTION FOR END FACE OF PLATED STEEL SHEET, METHOD FOR CHEMICAL CONVERSION TREATMENT OF END FACE OF PLATED STEEL SHEET, CHEMICAL CONVERSION TREATED STEEL SHEET, AND MOLDED ARTICLE

摘要

The objective of the present invention is to provide an anti-rust treatment solution capable of forming a chemical conversion treated film having higher corrosion resistance. The objective is achieved by an anti-rust treatment solution for an end face of a plated steel sheet, the anti-rust treatment solution including: an organic resin containing a fluorine resin;a Group 4 element-containing compound or ions of the Group 4 element; at least one bonding promoter selected from the group consisting of an n-methyl-2-pyrrolidone and an ester compound of an adipic acid or phthalic acid and a C1-C3 alcohol; and a silane coupling agent.
