Abstract

Moisture and corrosion resistant coating is formed on metal esp. a metal contng. Fe, Zn or Al in its surface, by phosphating the metal, then applying a coating contng. 0.1 g./l. vegetable tannin to the phosphated surface. Process prevents the formation of blisters on the surface of the metal. The metal is esp. steel, galvanised or clad with Al.
