Postcure

Definition(s)


Postcure

Additional elevated-temperature cure, usually without pressure, to improve final resin properties and/or complete the cure or polymerization of the resin matrix, or decrease the percentage of volatiles in the compound.

  • Note: 1 to entry: In certain resins, complete cure and ultimate mechanical properties are attained only by exposure of the cured resins to temperatures higher than those of curing (typically within to 30 °C to 50 °C of the maximum possible Tg).
