Description

 This product requires a catalyst! Please see our RTV Silicone Catalyst (3%).

RTV Silicone is a high strength RTV silicone moulding compound ideal for moulds for plaster and Jesmonite and most other modelmaking applications. Moulds made from RTV Silicone will give high quality reproduction with virtually no shrinkage and with excellent release properties. RTV Silicone has been designed to be easy to mix by hand with colour-coded catalyst to offer a visual aid to ensure mixing is complete.

The two components mix easily and because of its low viscosity RTV Silicone can be used without the use of a vacuum chamber. RTV Silicone also can be thickened with Silastic Thixo Additive to enable you to make skin moulds and to mould in-situ on site.
