It depends what you are trying to achieve but generally it is not too
critical. The maximum is about 95C and takes one hour. I use 65C for
about 3 hours (only because my moulding dishes cannot take 95C).
Apart from the curing time, the curing temperature will have some effect
on the overall flexibility but not significantly (AFAIK) - this can be
better controlled by adjusting the component ratio. I'm sure this will
have been documented somewhere in the literature.
