MintSil (Soft) opaque silicone rubber is a high quality silicone rubber suitable for creating moulds that require great flexibility. It is also ideal for creating moulds with intricate details.

Moulds made with opaque silicone rubber are great for spotting bubbles in resin castings (as bubbles are more visible on a coloured surface) so you can easily pop or release them.

MintSil (Soft) has great bubble release so you can create moulds without any bubbles affecting your mould cavities. It is also fast setting, so you can create moulds easily within a short duration of 30 to 40 minutes.

It is non-toxic, food-grade, skin-safe and safe to use indoors. Cures at room temperature.

An excellent choice for beginners due to its user-friendly 1 to 1 ratio.

If you are looking for an opaque silicone rubber that is firmer for greater stability, check out our MintSil (Firm) Silicone Rubber.

Cure inhibition:

Please take note that all silicone rubbers may be subject to cure inhibition by contaminants on the surface of the master, or the material of the master being used for mould making. If your silicone rubber does not cure, there could be a chance that your master is reacting with the silicone rubber.

Materials that may inhibit the curing of platinum silicones are: Sulphur-based clay, tin-cured silicone rubber, latex rubber, some paint products, some 3D-printed plastic materials, etc.

Uncured rubber can be difficult to remove from your masters and may stain them. We recommend performing a small test on your master before making your actual mould.
