SG C-Sil Shore A 30 is a condensation silicone. This Tin cure silicone has a 100A : 5B mixing ratio with a liquid catalyst. De Condensation silicone is a economical silicone that can be used for one-off molds of moulds with less lifespan then eurosil.
In contrast to the addition silicone, the condensation silicone has a limited shelf life because the hardener exits the silicone. This process starts from the curing process and continues for weeks after curing. This increases the chance of shrinkage over time. For durable molds consult our High quality Eurosil addition silicone materials.
