STEPAN MWA-310 is a phosphate ester and can be used as an emulsifier and extreme pressure agent in synthetic and semi-synthetic metalworking fluids. It can be used as a component of lubricants, gear and chain oils, metalworking fluids, hydraulic fluids, and plasticizers. STEPAN MWA-310 is soluble in water and slightly soluble in oil, yielding very low surface tension and critical micelle values (CMC) values.

Safety & Health
- Health Effects
STEPAN MWA-310 is slightly non-toxic orally (LD₅₀, rat>5500 mg/kg). See SDS for more information.
Packaging & Availability
- Packaging Type
- Standard Packaging
STEPAN MWA-310 is available in drums.
Storage & Handling
- Storage & Handling
Normal safety precautions (i.e., gloves and safety goggles) should be employed when handling STEPAN MWA-310. STEPAN MWA-310 is corrosive, contact with eyes and skin should be avoided. STEPAN MWA-310 should be stored in a cool, dry place in closed containers. See SDS for more information.
- Workplace Exposure
Occupational exposure can occur primarily through skin contact or via inhalation of vapors and mists. Engineering controls, personal protective equipment, and other workplace practices should be used to control these exposures. See SDS for more information.
- Product Benefits
- Imparts excellent corrosion inhibition, especially for aluminum metal.
- Alternative anionic emulsifier to heavy sulfonates for providing antiwear properties
