PHENOLIC ADMIX FOR ELECTRODEPOSITABLE COATING COMPOSITION CONTAINING A CYCLIC GUANIDINE.

摘要

The present invention is directed to an electrodepositable coating composition comprising a reaction product of an epoxy functional polymer and a cyclic guanidine, and a source of unreacted phenol, wherein the electrodepositable coating composition has a columbic usage of less than 100 coulombs/gram when deposited on a conductive substrate at a current density of ‰¤ 1.5 mAmps/cm². Methods of making the electrodepositable coating composition are also disclosed.
