Abstract: Surface treatment of metal blanks is achieved by applying an oxirane ring-containing compound in the gas phase to the surface of a metal blank maintained at a high temperature. According to this method, a covering layer which is much thinner than a conventional so-called adhesive primer coating layer and has a thickness of the angstrom order is formed on the surface of a metal blank.

Even if a lacquer containing a thermosetting resin instead of the thermoplastic resin is coated and dried on the metal surface treated with this bonding compound, a similar effect can be attained.
