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. Note: This product will not cure against surfaces containing sulfur, even when sealed. Smooth-Silª 960 is Food Grade compliant.

Compliance - The ingredients and ingredient levels in Smooth-Sil 960 comply with 21 CFR 177.2600, rubber articles for repeated use subject to the total extractive limits as specified and published in the Code of Federal Regulations. FDA compliance does not mean that Smooth-Sil 960 is FDA approved.

Using Mold For Bakingá Place mold on a baking sheet for greater stability and handling.á Do not expose rubber to temperatures above 400¡ F / 204¡ C. Do not subject molds to the broiler.á Silicone rubber does not distribute heat evenly. Food in shallow molds will bake faster vs. deep draft molds. Thick sections will retain heat longer than thin sections. Check frequently for doneness on first use.á Clean molds with soapy warm water and a soft sponge and rinse thoroughly between batches or prior to storing. You can dry the mold quickly in an oven. Bake for 5 minutes at 300¡F / 150¡C.
