T124 Tin Cure Silicone - All Kit Sizes

  • $38.00

T-124 is a high strength, pourable, two-component room-temperature curing (RTV) silicone rubber. Low in viscosity and easy to pour, we recommend this for duplication of models high in detail and with many undercuts.

Use the standard purple catalyst for about 60-90 minutes working time and a 12-18 hour demold time. For a faster cure, use the Medium-Fast Yellow Catalyst or Red Fast Catalyst for the fastest cure. Magikmold® T-124 is a pourable material; however, you can make it brushable with TinThix thixotropic additive.

For professional Use Only.
