Toray EX-1545
- Chemical Family
- Cyanate Esters
Toray EX-1545 is a 2-part highly modified, tough cyanate ester resin formulated to have extremely low viscosity at room temperature. The low viscosity allows RTM processing with minimal heat to the resin, which extends resin pot life and mold filling time for difficult and/or large RTM’d structures. EX-1545 displays both excellent mechanical and thermal properties in addition to low moisture absorption. Finally, the material is unique in that it develops full mechanical properties from its initial 177°C (350°F) cure. 177°C (350°F) Curing Toughened Cyanate Ester for RTM Applicationss
