Our Silicone is processed by adding the curing agent . The addition of 10% catalyst (by weight) has a pot life of 45 minutes and is ready for de-molding after 6 to 8 hours. Catalyst has a trace of pigment for good dispersion. After the mold has been removed from the master, it should be left for 24 hours in order to develop its maximum mechanical strength.
**Curing a mold quickly with extra catalyst or rapid set will decrease over all storage shelf life of molds and affect mold rubber properties.
