Two-Component Silicone That Cures at Room Temperature

Easy-to-use mold rubber for production molds and flexible rubber components.

Tin-cured silicone provides a practical workflow for mold making without heated equipment. These systems cure at room temperature into durable, flexible rubber suited for creating molds that hold shape and detail, as well as cast rubber parts that need strength and flexibility.

 

High-Strength Silicone for Demanding Molds

Build resilient molds that stand up to repeated use and challenging cast materials.

Silpak tin-cured silicones are formulated for strength, helping molds resist tearing and deformation during demolding and repeated casting cycles. This makes them a dependable option for shop environments where molds are handled often and pushed through frequent pours. 

 

Compatible with a Wide Range of Casting Materials

Mold rubber used to cast resins, metals, wax, soap, plaster, and more.

Tin-cured silicone molds are commonly used for casting polyester, urethane, epoxy, low-melt metals, thermoplastics, wax, soap, and plaster. They are also a strong choice for applications where a release-free casting process is required, supporting clean results across many materials and workflows.
