Abstract
Official abstract text for this publication.
A metal material is contacted with a treatment solution containing zirconium and/or titanium compound, and a polyamine compound having a number average molecular weight from 150 to 500,000 and containing from 0.1 mmol to 17 mmol of primary and/or secondary amino group per 1 g of solid content and at least one siloxane unit. Concentration of zirconium and/or titanium compound in the metal surface treatment composition is from 10 ppm to 10,000 ppm with respect to the metal element, and mass ratio of the zirconium and/or titanium element is from 0.1 to 100 with respect to the polyamine compound. The metal material is washed with water after contacted by the treatment solution.
