Toray RS-16

Toray RS-16 is a low temperature, low viscosity cure cyanate ester resin that can be used in wet winding, RTM, and VARTM processing. Its two-part construction allows easy and long-term storage while delivering excellent pot life. It is intended for lower temperature exposure with a moderate Tg requirement, and is an ideal system when used with different materials limiting the upper cure temperature. The system may also be cured using different combinations of cure/post cure temperatures and durations. 135°C (275°F) Cyanate Ester RTM Resion System
