TinSil® 70-60 Silicone Rubber

TinSil® 70-60 is a high hardness, 5A:100B mix, tin silicone liquid rubber that is designed to make molds for casting low melting (~600°F) metals (e.g., pewter, pewter blends, limited leads). No release agent needed for most applications.

TinSil 70-60 has limited tear strength because of its hardness.
