PROTECTIVE REACTION RINSE FOR AUTODEPOSITION COATINGS

摘要

The metal base the anti-self-water corrosion-deposited coating on the castle, the self-depositing the coating prior to curing the IIA group or the IIB group metal cations is enhanced by contacting the aqueous solution containing (e. G., Calcium or zinc cation), and phosphate. The rinsing solution is preferably acid, for example the calcium nitrate, and of zinc or can be prepared from hydroxy acid hydrogen phosphate. Optionally, the rinse solution may also include accelerators, such as hydroxylamine. ; Depositing the magnetic coating, the IIA group or the IIB group metal cations, phosphate, rinsing liquid, corrosion resistance, corrosion resistance
