Abstract:
A process of making a corrosion-protected coated metallic article of manufacture, said process comprising:forming over the surface of the metallic article to be protected a coating of a composition comprising: (A) a silane coupling agent component comprised of at least one type of silane coupling compound having one or more reactive functional moieties selected from among active hydrogen-containing amino moieties, epoxy moieties, vinyl moieties, mercapto moieties, and methacryloxy moieties; (B) a polymer component comprising at least one type of polymer that: conforms to the following General Formula 1: â€ƒwhere, independently for each instance General Formula 1 in the polymer: Y1 represents a hydrogen atom or a â€œZâ€  moiety that conforms to one of the following General Formulas 3 or 4: â€ƒwhere each of R3, R4, R5, R6, and R7 independently represents a hydrogen atom, a C1 to C10 alkyl moiety, or a C1 to C10 hydroxyalkyl moiety; and X represents a hydrogen atom, a hydroxyl moiety, a C1 to C5 alkyl moiety, a C1 to C5 hydroxyalkyl moiety, a C8 to C12 aryl moiety, a benzyl moiety, a benzal moiety, an unsaturated hydrocarbon moiety forming a naphthalene ring by condensation with the benzene ring to which General Formula 1 shows X is bonded, or a moiety conforming to the following General Formula 2:â€ƒwherein: each of R1 and R2 independently represents a hydrogen atom, a hydroxyl moiety, a C1 to C5 alkyl moiety, or C1 to C10 hydroxyalkyl moiety; and Y2 represents a hydrogen atom or a â€œZâ€  moiety as described above; has an average degree of polymerization of 2 to 50; and has a number of Z moieties that has a ratio to the number of benzene rings that is from 0.2 to 1.0; and (C) a wax component.
