STEPAN MWA-395 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-395 is soluble in water and slightly soluble in oil, yielding very low surface tension and CMC values. Phosphate esters have shown corrosion control for ferrous and non-ferrous metals.

- Standard Packaging
STEPAN MWA-395 is available in drums.
Storage & Handling
- Storage & Handling
- Safety precautions (gloves and safety goggles-face shield, if splashing may occur) should be employed when handling STEPAN MWA-395. Avoid contact with the eyes and skin. Wash thoroughly after handling material. See SDS for more information.
- Bulk Storage Information: Elevated storage temperature may be desirable to maintain ease of pumping, but product should be stored long term at ambient temperature.
- Non-Bulk Storage Information: STEPAN MWA-395 which has been stored in drums at temperatures below 50 °F (10 °C) may thicken or solidify. They may be fluidized by warming with a drum heater or in a steam room.Drums should be vented prior to heating to avoid excessive pressure build up. Product temperatures over 130 °F (54 °C) are not recommended.
