SORTA-Clear™ Series rubbers are premium water white translucent silicone rubbers (platinum catalyst) which cure at room temperature with negligible shrinkage. Available in Shore 18A, 37A and 40A hardness, these rubbers feature high tensile and tear strength. SORTA-Clear™ 37 offers the convenience of a 1A:1B by volume mix ratio. The 18A and 40A products require a gram scale for measuring parts A + B.
SORTA-Clear™ silicones are ideal for making prototype, jewelry or other molds of any configuration where model visibility is important (i.e. extracting a model from the mold via cutting). Materials such as urethane, epoxy or polyester resins can then be cast into SORTA-Clear™ silicone without application of a release agent. Other materials such as wax and low melt metal alloys can also be cast into SORTA-Clear™. SORTA-Clear™ can be pigmented with SILC Pig® silicone pigments.

Some Smooth-On Platinum Silicones are certified safe for food contact. Smooth-Sil™ 940,950 and 960 the SORTA-Clear™ 18 - 37 & 40 and the Equinox™ Series are suitable for making baking molds and trays, ice trays, casting butter, chocolate and other applications used to produce foods. These materials have been tested by an independent laboratory to comply with the total extractive limits when properly processed and heat cured. Refer to the technical bulletins for these materials for proper processing instructions (available at www.smooth-on.com). Post cure requirement - After rubber mold has been allowed to cure for 24 hours, expose to oven heat at 100° C for 4 hours. Let cool and wash mold cavity thoroughly with dishwashing detergent/water solution. Rinse thoroughly and allow drying before using. Compliance - The ingredients and ingredient levels in Smooth-Sil™ 940,950 and 960 the SORTA-Clear™ 18 - 37 & 40 and the Equinox™ Series Series 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™ 940,950 and 960 the SORTA-Clear™ 18 - 37 & 40 and the Equinox™ Series are FDA approved. To be approved, the user must also comply with all applicable FDA requirements. Compliance with 21 CFR 177.2600 does not authorize use of the compound for the manufacture of baby bottle nipples.
Using Mold For Baking
• Place mold on a baking sheet for greater stability and handling.
• Do not expose rubber to temperatures above 204° C.
• Do not subject molds to the broiler.
• 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
• 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 150°C.
