Coating composition for beverage containers

An aqueous beverage can end coating composition, the aqueous coating composition comprising:

• a polyolefin binder system;
• a nitrogen-containing carboxyl-reactive cross linker;
• an aqueous carrier fluid;
• the aqueous coating composition, when applied to a cleaned and chrome-free pretreated flat aluminum panel and cured for 12 seconds to a peak metal temperature of 249° C. to achieve a dried film thickness of approximately 12 grams per square meter, exhibits a log (resistance) of at least 6 ohms after one cycle including 10mV of AC current from 1,000,000 to 0.1 Hz followed by -2 volts of DC current for 20 minutes and with a surface of the cured coating exposed to an electrolyte solution;
• and
• the aqueous coating composition, when applied to a smooth release surface and cured for 12 seconds to a peak metal surface temperature of 249° C. to achieve a dried film thickness of approximately 12 grams per square meter and when removed therefrom and cut into a dog-bone shape using a die cutter fabricated according to the geometry pursuant to ASTM D-638 specimen type V, exhibits an average strain-at-break after being immersed for 45 minutes in 85° C. deionized water that is no more than 400% of an initial average strain-at-break prior to the deionized water immersion and upon a constant linear strain rate of 0.42 mm per second.
