METHOD FOR PRODUCING RESIN SOLUTION COMPOSITIONS FOR CR-FREE ANTI-FINGERPRINT PROPERTY HAVING HIGH CORROSION RESISTANCE WITH EXCELLENT CHEMICAL RESISTANCE AND CONDUCTIVITY, AND CR-FREE GALVANIZED STEEL SHEET COATED THEREOF

摘要

The present invention omit the traditional chromate and phosphate coating on galvanized steel surfaces and also from 0.9 to 1.3 g / m ² of chemical resistance and corrosion resistance while having a property of high electrical conductivity , as additional surface -fingerprint product for the general anti-fingerprint coating resin after conventional phosphate and chromate treatment by coating a polymeric resin relates to a chromium -free (Cr-free) anti-fingerprint coating resin liquid steel production to secure , its purpose is electroplated zinc demand is not growing in recent years , and that environmentally friendly consumer electronics market providing a surface treated steel containing chromium the chromium -free galvanized steel with resin solution and this method for plating steel surface treatment with a base .
