This product is a tin/condensation cured rubber and has been formulated to be a high quality flexible, elastic material with exceptional tensional and tear strength. There is almost no shrinkage (0.2%) and excellent reproduction of fine detail without the use of a vacuum chamber due to its low viscosity. It has a long mould life with outstanding release properties. This rubber is suitable for casting a wide range of materials in particular casting resins which we can also supply. Please see the bottom of the listing for examples of suitable casting materials.

The kit comprises of a white base rubber and a purple catalyst which provides a visual aid to ensure that the material is thoroughly mixed. We have also focused on minimizing the potential health risks to the user by formulating a non-toxic, non-flammable and virtually odourless catalyst unlike the majority of other condensation cure silicones that can use a toxic catalyst.

This product is not suitable for use with food. For a suitable product please click here

The catalyst is a skin irritant making this product unsuitable for applying directly to human skin for life casting. For a suitable product please click here

The maximum operating temperature is 180°C. For a high temperature rubber click here

This is a condensation/tin cured rubber so cannot be used as a mould for addition/platinum cured silicone rubbers as it will inhibit its cure.
