20210155810 · 2021-05-27 ·

The present invention addresses a problem of providing, for example, a metal surface treatment agent capable of forming a coating film that exhibits good corrosion resistance at edges, such as cut portions, of a coated metal material. The problem is solved by a metal surface treatment agent comprising: an ion (A) containing at least one kind of metal selected from zirconium, titanium and hafnium at a metal-equivalent molar concentration of 0.1 mmol/L or higher; and an aqueous urethane resin (B) having a weight-average molecular weight of 50,000 or higher at a solid mass concentration of 0.5 to 10 g/L, in which the ratio of a solid mass (B.sub.M) of the resin (B) to a metal-equivalent mass (A.sub.M) of the ion (A), [B.sub.M/A.sub.M], is 0.7 or higher.

ADHESION PROMOTER FOR THERMOPLASTIC POLYOLEFIN SUBSTRATE

An adhesion promoter for non-conductive surfaces is disclosed that combines a polyolefin with co-resins in a colloidal suspension in water. The colloidal suspension in water is prepared from mixing a solid-powder composition that includes the polyolefin and the co-resins with water. The colloidal suspension in water is applied to a low surface energy, non-conductive substrate, such as thermoplastic olefins, in order to make the substrates conductive for electrostatic painting.
