Cure Kinetics by DMA-isothermal
A dynamic mechanical analyzer is used with a parallel plate setup. An uncured sample is placed between the plates at a desired temperature and a time scan is run at a single frequency. The time scan is run until the material stops curing. From complex viscosity v. time, the cure kinetics can be obtained.
This test is performed at constant temperature. For non-isothermal (ramp) kinetics, please select R-028
The cure conversion v. time data is reported at the test temperature. Complex viscosity, G' and G" v. time are also available.

Curing kinetics is useful for deterimining the the rate at which materials "set-up" for a specified temperature. Many times it is useful to run multiple temperatures to determine temperature dependency on cure rate.
