STARTSO WORLD 80oz silicone mold kit

Highlights

This STARTSO WORLD silicone mould making kit is a food safe, platinum cured liquid silicone supplied in an 80oz set and designed for hobby casting and repeated use. It mixes at a 1:1 volume ratio, pours with low viscosity for easy mould making, and reaches initial cure in around 4–6 hours at 23°C, with full cure near 12 hours depending on thickness. The ease of mixing and bubble free behaviour helps you spend less time fixing imperfections and more time finishing projects.

Tech specs

• Name: STARTSO WORLD Silicone Mold Making Kit 20A
• Type: Platinum cured liquid silicone rubber
• Capacity: 80OZ
• Colour: Jade green
• Material: Food safe silicone

Benefits

The kit suits craft makers who want reliable, repeatable moulds without specialist equipment. Low viscosity and self-deaeration reduce trapped air, so detailed casts for resin, plaster, soap or chocolate come out clean according to the manufacturer. It is described as stretchable and reusable between 500 and 1000 times, which helps spread the cost over many projects. Note that cure times vary with mould size and ambient temperature, so allow extra time for thicker pieces.

Best use cases

For everyday use this silicone performs well when making small to medium moulds for resin casting, cake and confectionery moulds, wax or cement shapes. It is approachable for beginners as mixing is straightforward. It’s a good fit if you value food safe certification and a quick work cycle, and it makes sense if you prefer a product that handles fine detail without vacuum equipment. Ten in mind that very large moulds may need longer to fully cure.
