STEPAN® MWA-450

1 of 47 products in this brand
STEPAN® MWA-450 is a dea amide used as an emulsifier in soluble oils and 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. It can also help tighten emulsions, improve rust prevention, and provide lubricity. It should be considered a component for soluble oils where sodium sulfonates are not used.

Applications

STEPAN MWA-450 is a cochin oil-based amide produced via type 1:1 reaction between one mole of the ester of the fatty acid and one mole of the diethanolamine used as an emulsifier in soluble oils, synthetic and semisynthetic metalworking fluids. It can be used as a component of lubricants, gear and chain oils, metalworking fluids, hydraulic fluids, and plasticizers. STEPAN MWA-450 can helps tighten emulsions, improves rust prevention and provide lubricity. STEPAN MWA-450 should be considered as a component for soluble oils where sodium sulfonates are not used.

Storage & Handling

Storage & Handling
  • Storage & Normal safety precautions (e.g., gloves and safety goggles) should be employed when handling STEPAN MWA-425. Contact with the eyes and prolonged contact with the skin should be avoided. Wash thoroughly after handling material. See SDS for more information.
  • Non-Bulk Storage Information: It is recommended that STEPAN MWA-450 be stored in sealed containers and kept at temperatures not exceeding 120°F (49°C). As with all DEA amides, if overheating does occur, amide ester will be formed. To reverse the reaction, STEPAN MWA-450 should be stored at room temperature for approximately one week. Failure to do so may result in formulation products with decreased foam and low viscosity.
  • Bulk Storage Information: Tanks, piping and centrifugal pumps of carbon steel are recommended. Recommended storage for bulk tanks is 85-105°F (29-41°C).
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.
