Smooth-Sil® Platinum Silicones cure at room temperature with negligible shrinkage. With different hardnesses to choose from, Smooth-Sil® products offer tremendous versatility and are suitable for making production molds of any configuration, large or small. These silicones exhibit good chemical, abrasion and heat resistance. Materials such as plasters, concrete, wax, low-melt metal alloys or resins (urethane, epoxy or polyester) can then be cast into these silicone rubbers without a release agent.
Smooth-Sil® 935, 940 & 950 are mixed 100A:10B by weight, while new Smooth-Sil® 945 offers the convenience of a 1A:1B by volume mix ratio and a fast 6 hour cure time.

Processing Smooth-Sil® 940, the Sorta Clear® Series and the Equinox® Series of Rubbers for Food Related Applications
Some Smooth-On Platinum Silicones are certified safe for food contact. Smooth-Sil® 940, the Sorta Clear®
Series 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 212° F / 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, The Sorta-Clear® Series and the
Equinox® 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, Sorta Clear® 40, Sorta Clear® 18 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 400° F / 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 300°F / 150°C.
