Storage & Handling

Storage Information
  • Storage conditions: dry and cool place in factory-packed containers.
  • Solidification point: below 0 °C.
  • Apart from increased viscosity, no further deterioration of the material could be noticed at storage temperatures around 0 °C.
  • However, it is recommended to warm up the material to room temperature before usage.
