- Applications
Stepan Methyl Esters can be used as either solvents or cosolvents in metalworking, die casting and metal forming processes. STEPAN MWA-502 combines excellent characteristics of clean, low odor, high flash point and good film forming properties. STEPAN MWA-502 can be used as a non-staining additive for metal forming or metal removal operations on ferrous and non-ferrous metals.

Storage & Handling
- Storage & Handling
- Normal safety precautions (e.g., gloves and safety goggles) should be employed when handling STEPAN Methyl Esters. Use products away from sparks and open flame in a well-ventilated area. Contact with the eyes and prolonged contact with the skin should be avoided. Wash thoroughly after handling materials. Product temperatures over 130°F (54°C) are not recommended. See SDS for more information.
- STEPAN Methyl Esters can be stored in vessels of carbon steel, but 316 or 304 stainless steel is preferred. Tanks should be closed with venting through a gooseneck vent. The methyl esters should be stored between 90-110°F (32-43°C). External steam panel coils can be used if heating is required. Pumps, pipes, and transfer lines can be carbon steel, but 316 or 304 stainless steel is preferred. Rubber hoses are not recommended for extended use as methyl esters attack rubber. Drums should be stored in sealed containers at a temperature of 90-110°F (32-43°C). Storage under nitrogen will prevent degradation of the product over time.
- 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.
