Hexcel® HexPly® 954-3 Curing Cyanate Resin
Categories: Polymer; Thermoset; Epoxy
Material Notes: HexPly® 954-3 is a 350°F (177°C) curing cyanate resin with excellent resistance to moisture absorption, outgassing and microcracking. HexPly® 954-3 is formulated for autoclave or press molding using a standard cure of two hours at 350°F (177°C). Glass transition temperature can be maximized by post curing at 450°F (232°C). The recommended lay-up procedure is HSP-L3. The recommended cure procedure is HSP-C1 or HSP-C2.
Typical applications for HexPly® 954-3 include primary and secondary space structures and other applications where dimensional stability is critical.
