COATING COMPOUND COMPOSITION FOR LUBRICATED STEEL MATERIAL HAVING EXCELLENT CORROSION RESISTANCE

摘要

PURPOSE:To obtain the titled coating compound composition having excellent corrosion resistance especially in stacking, containing a specific acrylic resin, a mixture consisting of a specific sulfonamidocarboxylic acid and a cyclic amine and a water repellent in a specific ratio. CONSTITUTION:(A) 75-97.7wt.% acrylic resin having 20-160 (preferably 40-120) acid value and 5-100 deg.C (preferably 10-85 deg.C) glass transition temperature is blended with (B) 0.3-5wt.% rust preventive consisting of a mixture of a sulfonamidocarboxylic acid and a cyclic amine and (C) 2-20wt.% water repellent preferable example; carboxylic ester, metallic soap, PE fine powder or fluororesin fine (powder) to give the aimed coating compound composition.
