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.
EpoxAcoat™ WHITE
EpoxAcoat™ RED, GREY, WHITE and NEUTRAL are thixotropic epoxy gel coats which are widely used for hand laminating and tooling applications. They are tough and strong surface coat resins which cure at room temperature and offer exceptional abrasion resistance. EpoxAcoat™ NEUTRAL is formulated “color neutral” specifically for adding color pigments and fillers. For high temperature applications (to 284°F / 140°C) use EpoxAcoat HT™ (see separate technical bulletin).
