Description

[Smooth-On] A trademark for a series of two-component liquid silicone rubber compounds. Smooth-Sil (TM) Platinum silicones are cured with a platinum catalysts. These low viscosity rubbers pour easily and cure at room temperature with negligible shrinkage. Smooth-Sil is used for making molds of sculptures and architectural details. The molds can be cast with plaster, resins, and low melt alloys.
