This sulfur and tin-free technical plasticine are beneficial 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 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)
