Stabilizing emulsions and preventing corrosion for over 45 years.

A lot of metalworking is done in the presence of water — which can lead to corrosion if the right additives aren't used. Ingevity's corrosion inhibitors reduce staining and protect metal surfaces by providing a film barrier. Our multifunctional flagship corrosion inhibitor, Diacid 1550™, has been protecting metal for nearly half a century.

Diacid 1550 has dual acid functionality that gives the molecules a higher affinity to metal surfaces. This creates a chemical protective barrier, inhibiting corrosion across various metallurgies.
