How well do the two part epoxy masters hold up to the heat vulcanization process?
Epoxy models survive the process, but usually grow brittle due to the heat and pressure. Occasionally, after the mold is vulcanized, while the models are being removed from the mold, they will fracture or break (especially small parts). This breakage or fracturing in no way harms the mold. It harms only the master model’s ability to be used to make another mold. However, since the mold has already been produced at this point, a new master may be easily cast from it.
