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. If a thermoplastic resin layer is coated on the metal surface treated with this oxirane ring-containing compound, the initial adhesion and the adhesion after lapse of time are highly improved over these adhesions attainable by the conventional methods. 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. Accordingly, when an organic material is bonded or laminated to the so-treated metal surface or when metal-to-metal bonding is performed, a strong bonding can be maintained in the bonded portion.
