(Rebranded, previously known as RTV Silicone Base)

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

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

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