Solvay CYCOM® 977-6 Epoxy Laminate with T1000 Unidirectional Tape
Categories: Polymer; Thermoset; Epoxy

Material Notes: Cycom® 977-6 is a tough lower temperature curing modified epoxy resin. It is a versatile curing toughened epoxy resin which can be cured from 135°C to 177°C, depending on service temperature requirements. Following a 177°C cure, 977-6 has a 138°C dry and a 104°C wet service temperature. Cycom® 977-6 is formulated for lower temperature autoclave or press mold processing. Typical applications for Cycom® 977-6 include high performance automotive, aircraft primary and secondary structure, space structure, and any application where impact resistance and lightweight as well as versatile cure conditions are required.

Features & Benefits:

  • Toughened epoxy uses “co-continuous” morphology.
  • Very high impact resistance. CSAI up to 40ksi.
  • Controlled flow.
  • Tg of ~150°C following 3hr @ 135°C cure. (DMA G’)
  • Excellent cured surface finish.
  • 14 days shop life.
  • 12 months shelf life at -18°C
  • Available in a wide range of fibers and fabric weaves.
