SURFACE-TREATED METAL MATERIAL AND METAL SURFACE TREATING AGENT |
摘要 |
<p>The present invention provides a surface-treated metal material having a film formed on at least a portion of a surface of a metal material, the film containing at least polyurethane resin and silicon oxide, and a metal surface treatment agent used to obtain the surface-treated metal material. The polyurethane resin contains one or more of siloxane bond, dehydration-condensation bond of silanol group and different functional group, and silanol moiety, and urea bond. The sum of the siloxane bond, the dehydration-condensation bond of silanol group and different functional group, total amount of the silanol moiety, and the silicon oxide falls within a range of equal to or more than 1.6 wt% to equal to or less than 25 wt% for solids of the film. The ratio of the total amount of urea bond and urethane bond to the total amount of resin components falls within a range of equal to or more than 0.1 wt% to equal to or less than 10 wt%.</p> |
