Closed loop cooling water corrosion inhibition employing polymaleates and non-borate buffers
12546014 · 2026-02-10 · ·

A method of inhibiting corrosion of a metal surface in contact with an aqueous medium is provided. The method may include contacting the metal surface with a corrosion inhibitor composition where the corrosion inhibitor composition may include a compound or salt thereof of formula (I). The disclosed corrosion inhibitor composition is especially useful for inhibiting corrosion in closed loop systems. ##STR00001##
