Title:
METAL SURFACE TREATMENTS, METHOD FOR TREATING METAL SURFACE, AND SURFACE-TREATED METALLIC MATERIAL
Document Type and Number:
WIPO Patent Application WO/1997/003226
Kind Code:
A1
Abstract:
Metal surface treatments in the form of an aqueous solution, aqueous dispersion or emulsion, which at least comprises an organic polymer having at least one group selected from among the nitrogen-bearing groups represented by general formula (a) and cationic sulfur-bearing groups or salts thereof. The treatments enhance the corrosion resistance in a non-coated state (resistance to blacking with boiling water in the case of aluminum DI cans), and improve the slipperiness (lubricity) of metal surfaces, the adhesion of a coating thereto and the corrosion resistance in a coated state. In formula (a), R1 and R2 are each hydrogen, hydroxyl, optionally substituted linear or branched C1-C10 alkyl or optionally substituted linear or branched C1-C10 alkanol residue or in formula (b), R3, R4 and R5 are each hydrogen, hydroxyl, optionally substituted linear or branched C1-C10 alkyl or optionally substituted linear or branched C1-C10 alkanol residue.
