U.S. Patent 6,020,030. Feb. 1, 2000 J.D. Guthrie and A.M. Dennis, assignors to A l u m i n u m Company of America, Pittsburgh, Pa.
A process for pretreating an alum i n u m alloy sheet having a surface portion in order to improve adhesion of a polymer coating comprising in a first container, p r e t r e a t i n g an a l u m i n u m alloy sheet having a surface portion comprising a l u m i n u m oxide or a l u m i n u m hydroxide with a solution consisting essentially of water, an organophosphorus compound, and metal ions, thereby forming a layer comprising a reaction product of the compound and the oxide or hydroxide, and contaminating the solution with a l u m i n u m ions; t r a n s f e r r i n g at least a portion of the solution to a second container containing a cation exchange resin comprising a polymer functionalized with sulfonate groups and therein adsorbing a l u m i n u m ions onto the resin, thereby producing a treated solution containing the compound and having a reduced concentration of a l u m i n u m ions; and returning the
