This sulfur and tin-free technical plasticine is very useful when making silicone moulds.
Addition cure silicones are particularly susceptible to these two elements during the hardening process, so they are only allowed to come into contact with materials that are free of sulfur, tin and lead.
The technical plasticine can be helpfully applied for:
- making different supports o the model
- forming boundary walls
- building form casting funnels or air channels for the moulds (of a special design)
