CRAFT RESIN Silicone Mold Making Kit 15A 1kg | Soft & Flexible Platinum Silicone
Craft Resin 1 kg Soft Silicone for Mold Making is a flexible 15A silicone designed for creating detailed molds for resin crafts, jewellery, figurines, decorative pieces and other small creative projects. The soft Shore 15A formula creates flexible, moldable silicone rubber that captures fine details and bends easily around complex shapes and undercuts for easier demolding. This two-part liquid silicone rubber mixes at a simple 1:1 ratio, making the 1 kg size a practical choice for small molds, testing new designs and everyday mold-making projects.
- 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 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
