Precautions in Using MFP-CMB

  1. MFP-CMB is of hygroscopic nature. When stored for long period, it is likely to absorb moisture from air. Therefore, pay adequate attention to humidity at the storage place.
  2. When bubble formation is seen in the molded articles, there is a possibility of moisture absorption.
  3. Use after sufficiently drying the articles. If the moisture content exceeds 1000 ppm, possibility of bubble formation will become high.
