Abstract
It is an object of the present invention to provide an electrodeposition coating composition excellent in corrosion resistance and stability of the coating. The electrodeposition coating composition comprises, based on 100 parts by weight (solid basis) of a core resin and a hardener constituting an electrodeposition coating, 1 to 100 parts by weight of (a) a zinc powder dispersed by a phosphoric-acid-group-containing dispersing resin.
Claims9
An electrodeposition coating composition comprising, based on 100 parts by weight (solid basis) of a core resin and a hardener constituting an electrodeposition coating, approximately 1 to 100 parts by weight of (a) a zinc powder dispersed by a phosphoric-acid-group-containing dispersing resin, wherein the electrodeposition coating is an onium-salt-containing cationic one and the hardener is a block polyisocyanate.
