More Information
Summary:A water treating agent comprises (a) a mix. of a maleic acid or maleic anhydride polymer, or copolymer of maleic acid with isobutene or isopentene, copolymer of maleic anhydride with isbutene or isopentene, or their water-soluble salts, and (b) an acrylamide or methacrylamide polymer, or their Hofmann degradation prods., or their water-soluble salts. The agent is added to boilers and water coolant systems to inhibit corrosion and scaling.
