Food Safe Platinum Liquid Silicone

Sil-Craft 720 is a soft (Shore A-20) platinum cure liquid silicone that is perfect for making molds for casting tasty treats. You can safely bake with it, freeze it, refrigerate it, and when you're done, it's easy to clean!


Here's a few ideas to get you started:

Hot Foods:

  • Cake batter (for mini cakes or cupcakes)
  • Bread dough (for rolls or buns)
  • Brownie bites
  • Chocolate ganache
  • Rice Krispie treats
  • Baked eggs

Cold Foods:

  • Infused ice cubes or fruit cubes for drinks
  • Butter sculptures 
  • Chilled cheesecake bites
  • Tiramisu cups
  • Avocado mousse cups
  • Mini fruit tarts

– the applications are practically unlimited!

    Baking instructions:

    • A thicker mold will cook more evenly (better heat distribution), leading to more consistent results, even with repeated use. 
    • Place your mold on a baking sheet to ensure stability.
    • Do not use the broil setting on the oven.
    • Do not bake over 400°F (204°C). 

    Cleaning instructions:

    • Cleaning is effortless — simply wash your mold with dishwashing liquid and warm water, or run it through the dishwasher.
    • Clean thoroughly after each use to eliminate any odors from strong smelling foods and to ensure the longevity of your mold.

    Food Safety & Compliance

    Sil-Craft 720 platinum liquid silicone is hypoallergenic, non-toxic, inert, and contains no BPA, BPS, phthalates, or fillers.

    Sil-Craft 720 has been tested by an independent laboratory to comply with FDA 21 CFR 177.2600 for polymers intended for repeated use in producing, manufacturing, packing, processing, preparing, treating, packaging, transporting, or holding food.

      Additional Effects

      In order to remain food-grade compliant, we do not recommend adding pigments, thickeners, and fillers to food grade molds. 

      Handling Recommendations

      Working time is 30-40 minutes, and the mix ratio is 1:1 by weight, so please have a gram scale on hand. Vacuum degassing the material before pouring is required (you don't want trapped air in a food grade mold). Demold time is 3-4 hours (we wait 24).

      When properly cured at room temperature 73°F (23°C), Sil-Craft 720 has an operating temperature from -40°F to 400°F (-40 to 204°C).
