Product description

EX-1545 is a highly modified two-part toughened cyanate ester resin, formulated to have extremely low viscosity at room temperature. EX-1545’s 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, EX-1545 is unique in that it develops full mechanical properties from its initial 177°C (350°F) cure.
