Cure Cycle

Curing is recommended at 300°F (149°C), at least 15 psi (103 kPa), and cure time between 30-90 minutes.

Typical Cure Cycle:

  • Apply at least 15 psi (103 kPa)
  • Heat up to cure temperature at 2 – 5°F (1 – 3°C) per minute
  • Hold at cure temperature for at least 30 minutes
  • Cool down under pressure to below 120°F (49°C)
