CYCOM 977-3 is a 350°F (177°C) curing toughened epoxy resin with a 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 for six hours. The recommended lay-up procedure for this material is L-15. The recommended cure procedure is C-49.

Unidirectional tape and woven fabric impregnated with Cycom 977-3 resin will retain tack for 30 days at 72°F (22°C) and has a long mechanical outlife suitable for fabrication of large structures.

Typical applications for CYCOM 977-3 include aircraft primary and secondary structure or any application where impact resistance and excellent hot/wet performance are crucial.
