Description

PN-3M is a one-component phthalonitrile resin with operating temperature up to 450°C. The processability of this resin is similar to that of epoxy resins: impregnation is done at a temperature of 160°C, the preliminary curing at 180°C . PN-3M is designed for composite structures manufacturing by vacuum infusion and RTM.

Advantages:

  • Operating temperature up to 450°C;
  • Impregnation temperature is 160°C;
  • Pre-curing temperature is 180°C and post-curing temperature is 375°C;
  • Low moisture absorption;
  • Low viscosity;
  • Softening temperature is 80°C.
