Storage & Handling

Storage And Handling

Safe handling advice

  • Take precautionary measures against static discharges.

Storage/Transport pressure

  • Ambient

Load/Unload temperature

  • 21-65 °C (70-150 °F)

Storage and handling materials

  • Suitable: Carbon steel coated with baked phenolic. Any moisture may cause rusting of carbon steel. If product is moisture free, uncoated carbon steel tanks.

Further information on storage conditions

  • Mix thoroughly before use. When stored in the liquid form, ethoxylates should be padded with a dry inert gas, such as nitrogen, to prevent oxygen or air from entering the tank. Prolonged storage in the presence of air or oxygen may cause product degradation. Oxidation is not expected when stored under a nitrogen atmosphere. Inert gas blanket and breathing system needed to maintain color stability. Use dry inert gas having at least -40°C (-40°F) dew point.
