  • Process for applying anticorrosive coating onto automobile body
    Patent number: 4259163
    Abstract: A process is provided for applying an anticorrosive coating on an automobile body member. The process comprises subjecting the whole or lower portion of the body member to an electrodeposition in an aqueous bath containing (A) a cationic resinous binder and (B) a synthetic resin in the form of fine powder which is solid at room temperature but can melt at an elevated temperature, the weight ratio of (A)/(B) being 1/0.05-5. Subsequently the whole of the body member is subjected, without hardening the deposited film, to an electrodeposition in an aqueous bath containing an anionic or cationic resin. The thus treated article is washed with water and baked to effect the hardening thereof.
