Rust inhibitors, rust protection - coating composition and coating processes for the corrosion prevention of metal surfaces.

摘要

PURPOSE:To obtain a corrosion-resistant coating compound composition useful for automobiles and electric products, having excellent rust preventing effects on the surface of metals, by adding a bivalent metallic oxide containing aluminum as solid solution to a coating compound. CONSTITUTION:(A) 100pts.wt. coating compound is blended with (B) 0.1-30pts. wt. bivalent metallic oxide shown by the formula [(Zn)1-y(Mg)y]1-xAlxO1+x/2 (0.1x0.6 and 0y1) containing aluminum as solid solution to give a corrosion-resistant coating compound composition for improving corrosion properties on the surface of metal by the fact that the solid solution of oxide has activity to both Na ion and Cl ion causing corrosion and high activity thereof.
