ABSTRACT:
A corrosion inhibition and scale control method and composition are disclosed. The method comprises, adding to a cooling water system, for which protection is desired, a water soluble zinc salt, a cellulose gum material and an organo-phosphorus acid compound. Optionally, a corrosion inhibitor compound such as a 1,2,3-triazole or thiazole compound may be added to afford additional protection. Molybdate salts may also be included as optional corrosion inhibitors.
