MintSil (Firm) - Opaque Firm Silicone Rubber Size:5.5kg or any non-porous surfaceMintSil (Firm) opaque silicone rubber is a high quality platinum (addition cure) silicone rubber ideal for creating moulds that require firmness and stability. The silicone rubber has a temperature resistance of 200 to 220C, making it suitable for making baking moulds. Moulds made with opaque silicone rubber are great for spotting bubbles in clear resin castings (as bubbles are more visible on a darker surface), so you can easily pop or release them.
