Corrosion inhibitor and EP additive for lubricants in industrial applications
Hordaphos™ MDGB
Edition Date :
June 05, 2026
Hordaphos MDGB is an effective corrosion inhibitor for acidic aqueous systems. Typical applications are acid cleaners and inhibitors for metal surfaces in home, industry, and commerce applications. It is also suitable for use in water-miscible cutting fluids, where it acts as a highly active EP additive due to its low decomposition temperature.
