Silicone Mold Making Kit 66 oz SHORE RESIN, 15A Platinum Silicone Rubber | 1:1 platinum silicone with 30-minute work time, self-degassing flow and 4-hour initial cure for detailed DIY molds.

Description

• 1️⃣ 66 OZ FOR LARGER MOLDS & MULTIPLE PROJECTS — Includes 33 oz Part A + 33 oz Part B for larger molds, multiple small molds and repeat making. Suitable for resin casting, candle and wax, soap, plaster, clay, concrete and craft mold projects.
• EASY 1:1 TWO-PART SILICONE MIX — Mix equal parts A and B by weight or volume and stir thoroughly for 3–5 minutes. About 30 minutes of working time at 77°F/25°C gives more time to pour, position originals and fill detailed shapes.
• LOW-VISCOSITY LIQUID SILICONE FOR MOLDS — Smooth-flowing platinum-cure silicone reaches narrow details and intricate textures while helping trapped air rise naturally. Slow mixing and thin-stream pouring can help create cleaner molds.
• FLEXIBLE 15A SILICONE RUBBER FOR MOLD MAKING — Shore A 15 provides a practical balance of softness, flexibility and tear resistance. Cured molds bend around undercuts for easier demolding while preserving fine detail through repeat casting projects.
• 4-HOUR INITIAL ROOM-TEMPERATURE CURE — At about 77°F/25°C, initial cure is around 4 hours and full cure typically takes 4–6 hours. Larger molds, thicker pours or cooler rooms may require more time before demolding.
