Toray EX-1510
- Chemical Family
- Cyanate Esters
Toray 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 Applications 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.

- Crystallization
Part A has the potential to crystallize during storage depending on storage conditions. If this occurs, Part A should be heated, at 66°C (150°F) maximum, until the material becomes de-crystallized. Multiple de-crystallization cycles, at 66°C (150°F), have not shown any decreasein the room temperature shelf life of Part A. The de-crystallization temperature 66°C (150°F) is well below the temperature required to trimerize (cure) the uncatalyzed cyanate ester resin.

- Good Mechanical Properties
- Low Water Absorption
- HIGHLIGHTS
High radiation resistanc; Low microcracking even under severe thermocycling; Low moisture absorption; Low dielectric constant and dissipation factors; Low stress-free cure temperature with high level of cure; Outstanding mechanical properties; Compatible adhesive is EX-1516
- Pot Life
The mix ratio of EX-1510 is 100 Part A to 3 Part B by weight. Put the correct amount of Part A in the mix vessel first. Add Part B and mix using a high-speed dispersion mixer. Mix for 5 minutes, stop and spatula the walls and bottom of mix vessel, then mix an additional 5 minutes.. The mixed resin shall have a pot life of 4 hours minimum at 25°C (77°F). The pot life is the length of time a 150 gram mass of resin can be stored at a given temperature before doubling in viscosity. Any mass over 150 grams should have the temperature monitored after mixing and should have the appropriate safety procedures followed if the resin temperature increases by 17°C (30°F) over room temperature.
