Storage Information
  • PlastRetard XCL does not contain preservatives and it is stable when stored in its original packaging at temperatures that range from -10°C to 50°C.
  • If diluted with water and stored over days, PlastRetard XCL may turn a bit gelatinous.
  • If dilution is required for accurate metering, it is recommended that during extended production stops any unused material be disposed and replaced with a fresh batch prior restarting production.
  • Alternatively, it is possible to add a preservative as Benzoic Acid in the retarder solution.
    Metering is best done in undiluted form into the main process water feed using a one-way valve to prevent backflow of water.
  • The most appropriate pump to be used is a positive displacement screw pump (eg. Netzsch, Seepex or similar).
