Abstract: Methods for preparing an aluminum alloy sheet product for adhesive bonding are disclosed. A method may include preparing an aluminum alloy product for roll coating and roll coating an aqueous functionalization solution onto the prepared aluminum alloy product. For the roll coating step, the aqueous functionalization solution may include from 0.1 to 5.0 wt. % of active ingredients. The active ingredients may include a first monomer component and a second polymer component. The amount of second polymer component in the aqueous functionalization solution may be greater than an amount of the first monomer component in the aqueous functionalization solution.

Abstract: A method for extrusion coating both sides of a metal strip. A metal strip, such as aluminum alloy strip, is moved through a pre-conditioner, two extrusion dies, a post heater and a cooling system. Both sides of the strip are coated with thin coatings of polyester material. The coated metal strip is useful for containers, such as cans and can ends, as well as for automobiles, appliances, aerospace, construction and electrical devices.
