Abstract

Topcoat adhesion is now increased for coatings applied over a solvent phosphatized metallic surface. The phosphatized surface is obtained from a composition that can contain methylene chloride, as well as water in minor amount, and yet maintain a continuous and homogeneous liquid phase. By adding significant amounts of stabilizer to the phosphatizing composition, generally by way of an adjuvant composition, the resulting phosphatized coatings will provide for enhanced topcoat adhesion.
