SG C-Sil Shore A 20 is a condensation silicone. This Tin cured silicone has a mixing ratio of 100A: 5B (harder). The Silicone Condensation is an economic silicone that is often used for one-off or short-life molds. The SG C silicone is mostly used for making both small and large molds. The condensation silicone has a high mechanical resistance. The SG C-Sil is a white silicone with a transparent hardener. The viscosity is 24,000 cP and has a 90 minutes processing time. The cure time is 24 hours.
In contrast to the addition silicone, the condensation silicone has a limited shelf life because the hardener comes out of the silicone. This process starts from the curing process and continues for weeks after curing. As a result, the chance of shrinkage in time is high. For durable molds consult our High quality Eurosil addition silicone materials.
