CRAFT RESIN Silicone Mold Making Kit 1 Gallon/8.8 lbs – Platinum Liquid Silicone Rubber for Resin Casting, 1:1 Mix Ratio, Shore 30A, Bubble-Free Silicone Kit for Molds, Soap & Candle

Craft Resin Mold Making Silicone 30A is a premium platinum-cure silicone engineered for durable, high-detail mold making — ideal for resin casting, decorative elements, small sculptures, candles, soaps, and molds that require greater dimensional stability and long-term durability. With a Shore hardness of 30A, this silicone offers increased firmness while maintaining enough flexibility for clean, controlled demolding. It is well-suited for molds that must hold their shape, support heavier castings, or maintain precise geometry over repeated use. Its low to medium viscosity allows the silicone to flow smoothly around masters and capture fine surface details with minimal air entrapment when mixed properly. The material is mixed at a simple 1:1 ratio by weight, making accurate measuring straightforward with a digital scale. The silicone provides a comfortable working time and cures at room temperature in approximately 4 hours, allowing for efficient mold production without long wait times. Once cured, it exhibits minimal shrinkage and a smooth, non-tacky surface. This formula produces strong, tear-resistant molds compatible with epoxy resin, polyurethane, plaster, wax, and other common casting materials, making it a reliable choice for both workshop and studio environments. It has low odor and is non-toxic when used as directed, making it suitable for indoor use and home studios.

• ‌DESIGNED FOR MOLD MAKING & CASTING - Clear liquid silicone rubber for resin, soap and candle mold making with 15A Shore hardness. Сombines flexibility and dimensional stability. Designed to capture fine details and complex shapes while allowing easy demolding.
• SMOOTH POURING & HIGH DETAIL REPRODUCTION - Low-viscosity formula flows easily into complex shapes and small cavities, helping reproduce sharp edges, textures, and intricate details in resin casting molds.
• FAST CURE - This platinum silicone cures at room temperature in approximately 4 hours, allowing faster mold making and earlier casting. Cure time may vary depending on mold size and thickness.
