Shop Tin Cure Silicone

TinSil tin silicone mold rubbers are two-part, room temperature (RTV) curing systems that are used primarily for casting resins such as polyester, polyurethane, epoxy as well as polyurethane foams and low melting metals. This includes casting cold cast bronze art objects where the resin binder is EasyFlo 60 or EasyFlo Clear.

TinSil rubbers are pourable as supplied or can be thickened with TinThix liquid thickener for brush-on mold applications. 

TinSil systems do not require mold release and offer excellent chemical resistance and long mold life during casting.

TinSil molds do have a limited shelf-life when cured (library life) so they are not recommended for extended storage. TinSil 80-Series molds are designed for longer library life compared to TinSil 70-Series and other available tin silicone systems.

A brushable/sprayable version called TinSil Brush/Spray 25 is available for use by hand or with low cost, portable equipment.
