Mold Max™ Silicones are tin-cured silicone rubber compounds that have exceptional working properties and library life. Mold Max™ Silicones feature Smooth-On’s exclusive “Libra™” catalyst for long library life. Mold Max™ silicones can be pigmented with Silc Pig™ silicone colorants. Pot life for the pourable silicones is 45 minutes and they cure overnight at room temperature.
Vacuum degassing mixed material using a vacuum pump and chamber to remove entrapped air is recommended.
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.
