Solvay LTF 318B Epoxy Resin
Categories: Polymer; Thermoset; Epoxy

Material Notes: Description: LTM317-1B is an epoxy resin matrix specifically developed for the production of 150°C (302°F) capable mold tooling using vacuum bag processing. LTM317-1B, which can be supplied in both standard prepreg and ZPREG selectively impregnated formats, offers 65°C (149°F) initial cure capability, long out life and, after post-cure, resistance to thermal cycling up to 150°C (302°F). LTM317-1B can be used in combination with LTF318B ZPREG selective impregnation technology surface films and with LTS317 syntactic plies to achieve a high quality surface finish by vacuum-bag processing, thereby creating many new practical possibilities’ for the manufacture of affordable, high quality, composite tooling.

Features & Benefits:

  • 21 days out life at 21°C (70°F) for LTM317-1B and ZPREG format
  • 7 days out life at 21°C (70°F) for LTF3818
  • 12 months storage at -18°C (0°F)
  • 65°C (149°F) initial cure
  • DMA E’ onset Tg of 170°C (338°F) after post-cure
  • 150°C (302°F) continuous service temperature
  • Compatible syntactic ply LTS317 (PDS1181) for improved surface quality
  • Can also be supplied for autoclave processing
