Smooth-Sil Series Silicone Rubber

Smooth-On Smooth-Sil™ Platinum Silicones cure at room temperature with negligible shrinkage. With different hardnesses to choose from, Smooth-Sil™ 935, 940, 945, 950 and 960 products offer tremendous versatility and are suitable for making production molds of any configuration, large or small. These silicones exhibit good chemical, abrasion and heat resistance. Materials such as plasters, concrete, wax, low-melt metal alloys or resins (urethane, epoxy or polyester) can then be cast into these silicone rubbers without a release agent. Smooth-Sil™ 945 offers the convenience of a 1A:1B by volume mix ratio and a fast 6 hour cure time.

Smooth-Sil 940 is a food-grade silicone rubber suitable for making baking moulds and trays, ice trays, casting butter, chocolate and other applications used to produce food. Read more information about using Smooth-Sil 940 for food-related applications from the manufacturer.

Need a softer high-performance silicone rubber? The Dragon Skin™ series is available in Shore 10A, 20A, and 30A hardness.

NOTE: As with any addition-cure or platinum silicone rubber, exposure to sulphur and latex can lead to cure inhibition. Do not use sulphur-based modelling clay or wear latex gloves while processing Smooth-Sil. An accurate gram scale is required to measure the mix ratio for Smooth-Sil and vacuum degassing the rubber is highly recommended.
