Hot Pressing Cycle

  • Heat-up rate:1.0~2.5℃/min (80~140℃)
  • Curing time:>30min (170~180℃)
  • The hot pressing parameters are for your reference only. If you have any questions, please feel free to contact us.

Storage Conditions

  • 3 months when stored at < 23℃ and < 50% RH.
  • 6 months when stored at < 5℃. Normalize in room temperature for at least 4h before using.
  • Beware of moisture, always keep wrapped in damp-proof material. Keeping in normal condition, prepreg might absorb moisture and its bonding strength would be weakened.
  • Avoid UV-rays and strong light.
