Hardener HTG-245

High TG structural infusion epoxy system

  • High TG > 240°C
  • Low viscosity and high wetting out properties
  • High thermomechanical properties

RESOLTECH HTG-240 / HTG-245 epoxy system is very high TG resin specially formulated for the production of tooling and large structural composites parts requiring TG’s and service temperatures up to 240°C.

Due to its low viscosity, high wetting properties and excellent air release, this system is suitable for the manufacture of structures and composite parts by infusion, injection while guaranteeing low toxicity working conditions to the users. The stable low viscosity vs temperature makes the HTG-240 system a prime choice for infusion process.

This system guarantees high inter-laminar properties and impact resistance thanks to its exceptional wetting properties even on aramid reinforcements.

Laminates can be released from the moulds after a low temperature cure cycle (8h at 40°C recommended. Final thermo-mechanical properties will be obtained after a post curing cycle defined later in this technical datasheet.
