- Clearances
The international inventories (country clearances) of STEPAN MWA-560 HS can be found in Section 15 of the Safety Data Sheet (SDS). It is the responsibility of the formulator to review the chemical control regulations for each country where the end-product is intended to be sold or used.
Technical Details & Test Data
- Falex 4-Ball and Falex Pin and Vee Testing
Lubricity is measured using the Falex Four-Ball Wear test and is used to determine the wear-preventing properties of lubricants in metalworking applications. Lubricants are compared using the average size of the scar diameters worn on the three lower clamped balls. STEPAN MWA-560 HS shows improved lubrication by showing reduced average scar when compared to the current industry standard.

Storage & Handling
- Storage & Handling
- Normal safety precautions (e.g., gloves and safety goggles) should be employed when handling STEPAN MWA-560 HS. Contact with the eyes and prolonged contact with the skin should be avoided. Wash thoroughly after handling material. See SDS for more information.
- Storage in sealed containers at temperatures of 60-95°F (15-35°C) is recommended. 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 the SDS for further information.
