TinSil® 70-20 Silicone Rubber
TinSil® 70-20 is a 1A:10B mix, tin silicone liquid rubber. It is most useful for making molds for delicate castings because of the soft and flexible characteristics of the cured rubber. TinSil 70-20 has the highest elongation factor of all of the TinSil rubbers.
This rubber can be poured as supplied or thickened with TinThix liquid thickener to make brush-on molds.
Only available in a 44-lb kit.
