Addition (Platinum) Cure RTV Silicone
Silicone Rubber Systems
Hassle-free processing with Shin-Etsu easy transfer and releasable molds. Shin-Etsu RTV Silicone rubber for moldmaking is an excellent material that can be used for making replicas with a wide variety of different materials including polyester and epoxy resins, urethane foam and casting resin, wax, gypsum, concrete and low temperature composite. This moldmaking RTV rubber can be counted on to precisely reproduce the shape of the original model. Shin-Etsu moldmaking RTV silicone rubber is simple and straightforward to use. It is this ease of use and wide range of applications that make it the first choice in not only industrial applications but also among hobbyists who are looking to create the perfect replica.

Think of One-One mix silicones for ease of use in the field or in your shop. Have exact replication for your concrete, urethane foam or casting resin parts. No shrinkage when making your mold. No shrinkage in service. Cures at room temperature or speed them up with heat. This family offers Knotty Tear with uniquely high tear strength and outstanding mold life. These silicone rubbers are good for parts with large undercuts as well as for sizable heavy parts.
