The kit's single biggest advantage is the workable 1:1 mix ratio and low viscosity formula that largely self-degasses, making clean, detailed molds practical without a vacuum chamber. Beginners and experienced makers will both appreciate the included tools and the food grade, platinum-cured silicone that cures to a soft, flexible 15A shore hardness.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete kit:\u003c\/strong\u003e Includes 140oz (8.75 lb) silicone plus 15 wooden sticks, 10 gloves, ten 8oz graduated cups, two tablecloths and instructions so you can start immediately.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafe material:\u003c\/strong\u003e The silicone is food grade, translucent and platinum-cured, offering a non-toxic, odorless option suitable for candle and soap molds.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEasy 1:1 mixing:\u003c\/strong\u003e The equal-part mix ratio by weight simplifies measuring and reduces mistakes for reliable batch preparation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFast cure and working window:\u003c\/strong\u003e Roughly 30 minutes working time and a 3-5 hour cure at room temperature gives quick turnaround for most small to medium molds.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelf degassing:\u003c\/strong\u003e Low viscosity helps trapped air rise and break without vacuum degassing, producing fewer bubbles in finished molds.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible finish:\u003c\/strong\u003e At 15A hardness the cured silicone is very elastic, which aids demolding detailed resin and soap pieces without damage.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis kit is aimed at hobbyists and small-studio makers who make resin art, cast candles, pour soap or build 1-piece and 2-piece 3D molds and want a large initial supply.
