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 1kg 2 part liquid silicone rubber is ideal for repeated mold making and casting projects

Chloe ★★★★★

The pour was almost too easy—it flowed into every tiny nook of my ornament mold without a single bubble trap. Cured overnight to a soft, flexible 15A that peeled right off, and the fine detail came out crystal clear.

Jason C. ★★★★★

I make small jewelry pieces and the 15A firmness is perfect—not too stiff, not too floppy. The platinum cure means no nasty smell while I work, and the cured mold flexes just right to pop out even the tiniest details.

George I. ★★★★★

The pour was so smooth it picked up every tiny detail on my test piece, and the cured rubber is exactly as soft as advertised. Cured overnight without any fuss, and demolding was effortless—no tearing at all. I've already used the same mold three times and it's still holding its shape perfectly.
