    摘要： Disclosed are improved electrodeposition bath compositions comprising a resinous phase dispersed in an aqueous medium, the resinous phase being comprised of an active hydrogen containing ionic electrodepositable resin and a curing agent, where the improvement comprises the addition to a lead-free electrodeposition bath of at least one calcium compound in an amount of about 10 to 10,000 parts per million of total calcium and not more than about 200 parts per million soluble calcium, based on electrodeposition bath weight. The electrodeposition bath compositions are preferably cationic and provide for excellent corrosion resistance over a variety of metal substrates including untreated steel. Also disclosed is a method of electrocoating a conductive substrate using the improved electrodeposition bath compositions of the invention. Metallic substrates which are coated using the method of the invention are also disclosed.

    摘要： The invention relates to an anodic electrophoretic coating method. According to said method, a coating agent used in an anodic electrophoretic bath is compensated with an under-neutralised anodic refill material, said refill material consisting of A) a pigment-free aqueous binder component containing 40 to 70 wt. % solids and ≤0.5 wt. % of an organic solvent and with an meq value of 15 to 40 and B) a pigment-containing aqueous paste resin component containing 60 to 75 wt. % solids and ≤1.0 wt. % of an organic solvent and with an meq value of 5 to 15. The weight ratio of A) to B) is 1:1 to 4:1 and the mixture of A) and B) contains 45 to 73 wt. % solids and ≤0.75 wt. % solvent and has an meq value which is 50 to 70 % lower than that of the electrophoretic bath.
