Odourless and non-toxic. Simple 1:1 ratio and because of the low viscosity can be used without a vacuum chamber. They react to form a translucent beige/off white coloured flexible, elastic material with high tensional and tear strength.
There is practically no shrinkage (0.1%) and excellent reproduction of fine detail. Being an addition/platinum cured rubber its chemical and heat resistance (250°C) properties are superior to tin/condensation cure rubbers translating into a longer mould life.
