Product description

EX-1510 is a highly modified two-part toughened cyanate ester resin formulated to have extremely low viscosity at room temperature. Its viscosity allows resin transfer molding (RTM) to take place without the application of heat to the resin. This feature provides long resin pot life and mold filling time for difficult and/or large RTM’d structures and helps increase manufacturing efficiency and reduces waste.

EX-1510 displays 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. A freestanding post cure increases the heat resistance.
