Tin-Cure Silicone

Tin-based silicone, also called condensation-cure silicone, are two-component materials which cure at room temperature (RTV) to flexible, high tear-strength rubbers. Tin cured silicones can be poured onto models or they can be made brushable by adding a thixotropic additive. They are ideal for molds where easy release or high temperature resistance is required. Tin cured silicone can be used for casting polyurethane, epoxy or polyester resins, waxes, all gypsum products and low-temperature metals.

Mold Max Series

Mold Max silicones are used around the world for a variety of industrial and art-related applications including architectural restoration, prototype model development, reproducing sculpture, creating special effects and themed environments. There is no better silicone value.
