ABSTRACT:
A method for stabilizing metal ions in recirculating water systems is disclosed. This method utilizes an admixture comprising a) an ethylenically unsaturated water-soluble polymer and/or a water soluble phosphonate, b) methylene bis(thiocyanate), and c) 2-(thiocyanomethylthio)benzothiazole to solubilize metal ions thereby reducing deposition and corrosion.
