ABSTRACT:
A process for improved corrosion protection of a metal substrates involving organic vapor deposition of a thin film by polymerization of certain precursors onto one side of the phosphated flat metal substrate (15). Following stamping and assembly of the metal substrate, a primer and topcoat may be applied over the other side of the metal substrate. The process is particularly applicable to coil steel employed in the original manufacture of automobiles, trucks, and parts thereof.
