Solvay CYCOM® 977-6 Epoxy Prepreg Neat Resin
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.
