Material Notes:

HexPly® 954-3A is a 350°F (177°C) curing cyanate resin with a 400°F (204°C) glass transition temperature. Standard cure is two hours at 350°F (177°C). Glass transition temperatures can be maximized by a free-standing post cure at 450°F (232°C). HexPly® 954-3A is a controlled flow cyanate resin designed for autoclave and vacuum bag curing. HexPly® 954-3A can be impregnated on all available fibers and fabrics. The recommended lay-up procedure for HexPly® 954-3A is HSP-L3. The recommended cure procedure is HSP-C1. Typical applications are primary and secondary space structures where dimensional stability and low moisture absorption are required.Information provided by HexCel
