Claim Text:
1. A method for bonding a first substrate comprising a blend of polyether block amide and styrene/maleic anhydride copolymer a second substrate, the method comprising: cleaning a surface on the first substrate with a first aqueous cleaning solution comprising oxalic acid to form a first clean prepared surface; applying an aqueous primer to the first clean prepared surface on the first substrate to form a primed surface on the first substrate; applying a water-borne adhesive to the primed surface on the first substrate to form an adhesive-coated surface on the first substrate; applying an aqueous primer to a second clean prepared surface on the second substrate to form a primed surface on the second substrate; applying a water-borne adhesive to the primed surface on the second substrate to form an adhesive-coated surface on the second substrate; and contacting the adhesive-coated surface on the first substrate with the adhesive-coated surface of second substrate to bond the first substrate and the second substrate.
