HexPly® 954-6 is a 250ºF (121ºC) curing toughened cyanate resin with 300ºF (149ºC) Tg. HexPly® 954-6 is formulated for autoclave curing. Recommended cure is three hours at 250 F (121ºC). Service temperatures are maximized by a post cure of 350ºF - 450ºF (177ºC - 205ºC). The recommended lay-up procedure is HSP-L3. The recommended cure procedure is HSP-C4. Typical applications for HexPly® 954-6 include space structures, such as solar arrays, antennae and support structures, or any application where impact resistance, light weight, excellent dielectric and low outgassing properties are required. HexPly® 954-6 can be impregnated on all available fibers and fabrics.
