Cyanate Ester EX- 1510 Resin
Guidelines and Handling Procedures
The following guidelines are provided to our customers to assure that all customers are
aware of how to attain the best possible results from TenCate Advanced Composites’
Cyanate Ester products. This resin system will provide sound composite hardware and
structures if some simple procedures are followed. Keep in mind that these procedures
are recommended practices and should be refined for specific applications as required.
Storage Conditions and Shelf Life
Part A: Store Part A at room temperature. The shelf life of Part A is twelve months.
Part B: Store Part B at room temperature. The shelf life of Part B is twelve months.
Crystallization: Part A has the potential to crystallize during storage depending on
storage conditions. If this occurs, Part A should be heated, at 150°F maximum, until the
material becomes de-crystallized. Multiple de-crystallization cycles (at 150°F) have not
shown any decrease in the room temperature shelf life of Part A. The de-crystallization
temperature (150°F) is well below the temperature required to trimerize (cure) the uncatalyzed
cyanate ester resin.
Moisture Absorption and Sensitivity
While very resistant to moisture absorption after cure, Cyanate Esters can be adversely
affected by moisture uptake prior to cure. For this reason, all materials must be at room
temperature prior to opening the sealed container to avoid condensation on the
material. Cyanate Ester materials should always be sealed from moisture during
storage.
Mixing
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 five minutes, stop and spatula the walls and bottom of
mix vessel, then mix an additional five minutes.

Mixed Pot Life
The mixed resin shall have a pot life of four hours minimum at 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 30°F over room temperature.
Safety Procedures
Any amount of mixed resin that will not be used within the pot life should be disposed of
quickly and safely. One method of disposal is to cure the resin into a thin layer in a large
container. The thickness of the resin should be less than 0.1 inches to minimize the
exothermic reaction during cure. Specific resin disposal procedures should be
developed for your application with the appropriate safety procedures and/or
organizations involved.
