LET'S RESIN 20A 36oz Silicone Mold Making Kit, Flexible & Bubble Free Silicone Rubber, Translucent & 4H Fast Cure Liquid Silicone for Mold Maker

This platinum silicone mold making kit (20A hardness) offers a great balance of flexibility and durability, with higher abrasion resistance and support than softer silicones—perfect for larger molds that need to hold shape. It’s bubble-free without a vacuum machine, works at room temperature, and lets you add colorants for custom looks. Low viscosity makes it easy to pour and ideal for candles, soaps, and various mold sizes. The 1:1 mix ratio cures in 4–6 hours, simple for both pros and beginners.

• Outstanding Flexibility & Enhanced Durability: The silicone mold making kit with a hardness of 20A combines flexibility and durability. The 20A silicone rubber offers enhanced supporting force for the finished silicone mold, ensuring no deformation even for larger products. Additionally, the 20A silicone mold is much more durable than the 10A. Its abrasion resistance is 150% to 200% that of the 10A silicone
• Bubble Free & DIY Colors： Our platinum silicone self - defoams without needing a vacuum machine. (Note: High temperatures shorten curing time, leaving insufficient time for bubbles to disappear. Operate at room temperature. We've upgraded the formula to be more transparent. You can observe the master mold and bubbles during pouring to make adjustments. We also provide the option to DIY mold colors by adding colorants or powders to create your preferred - colored molds
• Widely Application: 20A liquid silicone, possessing moderate flexibility, low viscosity, and good fluidity, has a wider application than other low-hardness silicones. It can replicate master molds of all sizes. If the master mold is structurally stable and not easily deformed, like those for candles and soaps, it can be replicated precisely. 10A and 0A hardness silicones, being relatively soft with poor support, are more likely to deform and thus more suitable for small master molds. 30A hardness silicone, with its relatively high hardness and insufficient flexibility, has difficulties in demolding and is prone to damage when making smaller molds
• Easy to Use & 4 - 6h Fast Cure: Both professionals and beginners can easily master the usage. Our silicone mold kit is simple to operate. Just mix it in a 1:1 weight ratio, stir evenly in one direction for 3 - 5 minutes, pour, and wait for curing. It cures quickly, fully curing within 4 - 6 hours. (Note: The curing time may vary slightly due to different mold sizes and thicknesses
