METHOD FO PRODUCTION ANTI-FINGERPRINTING RESIN COMPOSITIONS HAVING HIGH LUBRICATING PROPERTY AND CHEMICAL RESISTANCE, AND CR-FREE ELECTROGALVANIGED STEEL SHEET COATED THEREOF

摘要

The present invention is excellent in workability by giving a high lubricating activity by coating only the anti-fingerprint coating material without the phosphate treatment and chromium coating treatment that had an excellent effect on the corrosion resistance and chemical resistance to the electro-galvanized steel sheet used for home appliances The surface of computer cases, copiers, and electronics, which are frequently hand-held in the molding assembly process and products, has no damage to resins on the surface even if it is deteriorated due to sweat discoloration and degreased by strong alkalis with a pH above 12 It relates to an anti-finishing coating composition for electro-galvanized steel sheet excellent in high quality chemical resistance and a method for producing a surface-treated steel sheet coated with the same.
