Product Description

Smooth-Sil™ 936

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-Sil936 is a lower viscosity platinum silicone rubber (21,000 cps).  It is easier to mix, vacuum degas and pour. Smooth-Sil™ Platinum Silicones are used for rapid prototyping, wax casting (foundries and candle makers), architectural restoration and for casting concrete.
