Pebeo Gedeo Siligum is a very fast-drying two-component silicone moulding paste. It's extremely easy and quick to use, taking less than a minute to mix the two parts, and just 10 minutes to produce a finished mould. It's ideal for making moulds from small and/or flat objects, which you can then use to cast plaster, crystal resin, wax and even metals with a low melting point. It gives you exceptional imprint accuracy. We sell Pebeo Gedeo Siligum in two pack sizes: 100g and 300g.
