White Corrosion Inhibitor for Metalworking Fluid

White Corrosion Inhibitors for metalworking fluids play a crucial role in protecting metal surfaces from a specific form of corrosion known as “white rust.” These inhibitors are designed to address the challenges posed by galvanized surfaces and certain metals that are prone to this type of corrosion when in contact with metalworking fluids.

Metalworking fluids are essential in machining and manufacturing processes as they provide lubrication, cooling, and chip removal. However, without proper corrosion protection, the metal components being processed can suffer from premature degradation. White corrosion inhibitors work by forming a protective layer on the metal surface, preventing the formation of white, fluffy, or waxy corrosion products.
