| Product Overview: Smooth-On Smooth-Sil™ Platinum Silicones cure at room temperature with negligible shrinkage. With different hardnesses to choose from, Smooth-Sil™ 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™ 936 is a lower viscosity version of Smooth-Sil® 935 platinum silicone rubber (21,000 cps vs. 40,000 cps). It is easier to mix, vacuum degas and pour. Smooth-Sil™ 945 offers the convenience of a 1A:1B by volume mix ratio and a fast 6 hour cure time. Cured Smooth-Sil™ 945 is skin safe and certified by an independent laboratory. Smooth-Sil™ Platinum Silicones are used for rapid prototyping, wax casting (foundries and candle makers), architectural restoration and for casting concrete. Smooth-Sil™ 940, 950 and 960 are suitable for food related applications.
