Inquiry (采购产品): Alternative Conversion Coatings Hello, I am with the Portland Water Bureau and we are looking into alternatives for the conversion coating we are using for one of our cast iron needle valves. Currently, we are using a zinc phosphate conversion coating in conjuction with paraffin. We are interested in other processes that may provide similar corrosion protection and wear resistance. Any information about similar processes and cost information would be greatly appreciated. Thank You, Doug Parkhurst **** Hidden Message ***** Doug Parkhurst OR 97204 USA Company: Water Bureau City of Portland E-mail: dparkhurst_z@ci.portland.or.us **** Hidden Message ***** dparkhurst_z@ci.portland.or.us
