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-Sil™ 936 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.
TASK™ 6
TASK™ 6 low cost, high performance casting resin yields castings that are tan and virtually bubble free. This resin offers superior physical and performance properties compared to our popular Smooth-Cast™ Series of general purpose casting resins. Vacuum degassing is not necessary and it offers the convenience of a 1A:1B by volume or weight mix ratio.
TASK™ 6 has high tensile and flexural strength, as well as high flexural modulus. This plastic was formulated for a variety of industrial applications including pattern making and making prototype models. This resin is designed for casting in thicknesses up to ½” (1.27 cm).
