Solvay CYCOM® 977-3 Neat Epoxy Resin
Categories: Polymer; Thermoset; Epoxy

Material Notes: CYCOM® 977-3 is a 350°F (177°C) curing resin. It is a toughened epoxy resin with 350°F (177°C) dry and 270°F (132°C) wet service capability. CYCOM 977-3 is formulated for autoclave or press molding and can be cured at 350°F (177°C) for six hours. Unidirectional tape and woven fabric impregnated with CYCOM 977-3 resin will retain tack for 21 days at 72°F (22°C). It has a long mechanical out life suitable for fabrication of large structures.

Features & Benefits:

  • 350°F (177°C) cure
  • Available on fabric and tape
  • 350°F (177°C) dry service temperature
  • 270°F (132°C) wet service temperature
  • Laminate and sandwich panel usage
  • Autoclave or press mold processing
  • Toughened epoxy using proprietary “cocontinuous”morphology
  • Impact resistance
  • Shelf life of 12 months at 0°F (-18°C), 21 days at 72°F (22°C)
Applications:
  • Aircraft primary and secondary structure
  • Applications where impact resistance is critical
  • Applications where hot/wet performance is crucial
