Storage & Handling

Storage and Handling Information
  • Functional MH-4500 should be warmed to about 50°C (120°F) to facilitate pumping and handling.
  • The base oil should be heated to 60-80˚C (140-180˚F) during blending to allow for good mixing.
  • Mixing time will vary with equipment but is typically at least one hour
