Armolube® EM 203 is a readily biodegradable ethoxylated amine based on tallow alkylamine. It provides moderate alkalinity to formulations and multifunctional benefits to metalworking fluids, hydraulic fluids, and industrial cleaners, particularly as an emulsifying additive. Armolube® EM 203 is a weakly cationic co-emulsifier and wetting agent, and demonstrates excellent oil-in-water (O/W) co-emulsification and hard water tolerance, as well as high stability in acid and alkali systems. It is ideally suited for cutting and grinding fluid formulations and emulsifying Group II mineral base oils The additive also provides friction modification, lubrication, detergency, dispersancy, and corrosion inhibition. In water-based hydraulic fluid formulations, Armolube® EM 203 acts as a co-thickener, helping control the fluid's rheology. It is also commonly used in industrial cleaning formulations, including metal parts cleaning.
