  Cure Cycles
  • 90 minutes at 350°F (177°C), or
  • 120 minutes at 300°F (149°C), or
  • 180 minutes at 275°F (135°C), or
  • Typical Cycle: From room temperature (70°F or 21°C) raise to 350 +0/-10°F (177 +0/-6°C) in 70-140 minutes, hold at 350 +0/-10°F (177 +0/-6°C) for 120 ± 10 minutes. This cure is in an autoclave, blanket press, or platen press at 45-85 PSI (310-586 MPa).
