Pretreatment compositions bonded to metal substrates and methods of making the same

A graft copolymer pretreatment composition, comprising:

• a polymer backbone;
• at least one surface binding or bonding moiety attached to the polymer backbone and configured to bind or bond the polymer backbone to a first surface of a metal product;
• at least one functional moiety attached to the polymer backbone which comprises a polymer side chain that provides a lubricating function and configured to provide at least a first surface functionalization to the first surface of the metal product;
• and
• at least one second functional moiety attached to the polymer backbone and configured to provide at least a second surface functionalization to the first surface of the metal product, wherein the at least one functional moiety and the at least one second functional moiety provide a multi-functional surface coating.
