Solvay CYCOM® 997 Epoxy Resin
Categories: Polymer; Thermoset; Epoxy

Material Notes: CYCOM® 997 resin is a controlled flow, 350°F (177°C) curing toughened epoxy resin with 350°F (177°C) dry and 270°F (132°C) wet service temperature capability. CYCOM 997 is formulated for ease of processing with excellent tack and drape. These properties are retained for up to 20 days at room temperature in the prepreg form. The mold life of this material is approximately 30 days. A standard two hour cure at 350°F (177°C) may be used in either an autoclave or press mold. No post cure is required to achieve service temperatures.

Features & Benefits:

  • 350°F (177°C) cure
  • Toughened epoxy using thermoplastic toughening mechanisms
  • Controlled flow for ease of processing
  • Used in both laminate and sandwich panels
  • 350°F (177°C) dry service temperature
  • 270°F (132°C) wet service temperature
  • Excellent tack and out time
  • Available in a broad range of fibers
  • Available in a range of forms including unidirectional tape, fabric and fiber placement tape
Suggested Applications:
  • Primary and secondary aircraft structures
  • Any application where impact resistance and excellent hot/wet performance is crucial
