This batch of silicone rubber is reaching the end of its shelf life (Part B is very viscous) hence we are clearing it at a very low price. The silicone rubber still can be used, it will just have a much thicker viscosity when mixed. Sold in a set of 200g.Mix Ratio: 1:1 by weight
Hardness: Shore 15A
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.
