Abstract
A corrosion inhibiting additive and methods of making the corrosion inhibiting additive are described. The corrosion inhibiting additive comprises a metal appended deactivated aromatic compound. The method includes reacting a metal salt with a deactivated aromatic compound to form a metal appended dichloro-diphenyl sulfone. Corrosion inhibiting coating compositions including the metal appended deactivated aromatic compound are also described.
