Craft Resin Silicone 15A is a soft platinum-cured liquid silicone rubber for flexible mold making and casting. It is designed for projects that need fine detail, easy release, and reliable results. This formula is a great choice for makers who want a simple process, smooth pouring, and clean finished molds for creative and practical applications.

  • Easy 1:1 mix by weight - simple to prepare, mix, and pour for smooth, consistent results with less mess and less guesswork.
  • Soft 15A flexibility - helps release delicate cast pieces more easily and works well for detailed shapes that need a softer, more flexible mold.
  • Low-viscosity formula - flows into fine details and helps reduce trapped bubbles for cleaner surfaces and more accurate results.
  • Low-odor, food-safe formula - more comfortable to use indoors and suitable for a wide range of applications where versatility matters.
  • Fast room-temperature cure - cures in around 4 hours for a quicker workflow, so you can move from mold making to casting sooner.
  • Ideal for creative projects - great for resin, soap, candles, plaster, and other detailed casting work where flexibility and clean release are important.

The 4kg 2 part liquid silicone rubber is ideal for repeated mold making and casting projects

Avery F. ★★★★★

The bubbles worked themselves out quicker than I expected with this platinum silicone, and the cured mold peeled off my original part without any tearing. I cast a small figurine with fine facial details and every line came through sharp on the first try.

Benjamin ★★★★★

The 2:1 mix ratio meant I could measure it out without a scale, and the 15A softness made demolding my coasters a total breeze. It captured every tiny texture line, even in the sharp corners, and I’ve already pulled six casts without any tearing.

Violet U. ★★★★★

The pour was so smooth and bubble-free, and the cured mold peeled off my prototype like it was nothing, catching every tiny texture. I've made three molds already and the softness is perfect for demolding without tearing thin details.
