Product Description
Smooth‑Sil™ 960
Smooth-Sil™ 960 is a Shore 60A platinum cure silicone rubber developed for a variety of industrial applications. Compared to other 60A platinum silicones, Smooth-Sil™ 960 has a relatively low viscosity and is easy to mix, de-air and pour. Silicone cures in 16 hours with negligible shrinkage to a firm rubber with high tensile and tear strength.
Smooth-Sil™ 960 offers good chemical and heat resistance, making this a good choice for production casting of resins and expanding foams. Because of its firmness, Smooth-Sil™ 960 molds are also used for spin casting. It is also used for embedding and electrical applications. Smooth-Sil™ 960 is suitable for food related applications.
Note: This product will not cure against surfaces containing sulfur, even when sealed.
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).
