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.

Refer to the technical bulletins for these materials for proper processing instructions (available at 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.

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.
