    摘要: Disclosed is a phosphate-free aqueous acidic conversion coating comprising zinc sulfate and sulfuric acid. The conversion coating finds special use as a conversion coating to metal substrates prior to application of a cold forming lubricant or prior to application of a paint. The conversion coatings according to the present disclosure avoid the issues associated with phosphate containing conversion coatings but provide similar benefits to phosphate-based conversion coatings. Optional components of the conversion coating solutions include one or more of pH adjustment neutralizers, coating stabilizers, coating accelerators, coating refiners, etchants, paint adhesion promoters and mixtures thereof. In an additional option, manganese oxide can be used in place of zinc oxide.
