TinSil® 80-40 Silicone Rubber
TinSil® 80-40 is a 1A:10B mix ratio, tin-cured silicone with a mid-range hardness and a tough, snappy, high-tear cure.
Molds made from TinSil 80-40 are often used for casting polyurethane, epoxy and polyester resin, as well as foam, wax, soap, plaster, and more. Release agent is not required for most casting applications.
This rubber can be poured as is, or can be thickened with TinThix liquid thickening agent for brush-on molds.
