Park Aerospace Nelcote® E-752 Epoxy Prepreg, 6K 5HS T300 Reinforced
Categories: Polymer; Thermoset; Epoxy

Material Notes: Nelcote® E-752 is a toughened, 185°C cure epoxy system designed for demanding structural applications up to 130°C. E-752 offers a good balance of toughness, high service temperature and good moisture resistance, as well as excellent tack and drape. Formulated for both oven and autoclave cure, E-752 provides for easy processing with oven cure, without sacrificing mechanical properties.

Key Features and Benefits:

  • Specifically designed to allow both oven cure and autoclave cure
    • Allows oven curing without sacrificing mechanical properties
  • Service temperatures up to 130°C
  • Controlled flow for ease of processing
  • Flexible cure temperature 132°C to 185°C
    • Good mechanical properties can be achieved through oven curing at 132°C, followed by post-cure at 185°C
  • Self-adhesive grade for sandwich panel applications

Applications/Qualifications:

  • Primary and Secondary Aircraft Structures
  • Ducting
  • Fairings
  • Nacelles
