Plasticine – Non-Hardening Modelling Compound for Model Making and Mould Making

Premium Non-Hardening Plasticine for Modelling, Mould Making and Sealing Seams

Plasticine is a synthetic modelling compound that, unlike ordinary clay, stays soft and does not dry out. You use it as a substitute for clay or wax to model, to seal seams and gaps in a casting mould or to fill air bubbles in a wax model. The compound consists of waxes, oil, an emulsifier, mineral fillers and pigments and is available in eight colours. The Grey – for Addition Silicones variant is specially suited for use with addition-cure silicones, such as the food-safe silicones in our webshop: it has no adverse effect on curing. The coloured variants, however, can prevent or hinder the curing of addition silicones. Plasticine can be completely melted out in an oven and keeps for at least 5 years in closed packaging.

Key Benefits

• Stays soft: does not dry out or harden – you can keep modelling or correcting at any time.
• Grey for addition silicones: does not inhibit the curing of our addition silicones – ideal for mould making with platinum and food-safe silicones.
• Three ways to work: modelling at room temperature, sealing at 25 to 30 °C and repairing at 35 to 40 °C – one compound for modelling, sealing and repairs.
• Fully meltable: in the oven up to a maximum of 90 °C – residues are easily removed from moulds and models.
• Eight colours: grey, white, black, red, blue, yellow, green and purple – for clearly visible details and stop-motion figures.
• Long shelf life: at least 5 years in closed packaging – you always have plasticine to hand.

Typical Applications

• Sculpting models and figures as a substitute for clay or wax
• Sealing seams and gaps in casting moulds and mould boxes
• Building up the parting surface for a two-part casting mould
• Filling and repairing air bubbles in wax models
• Mould making with addition silicones and food-safe silicones (Grey – for Addition Silicones variant)
• Stop-motion figures, props and set building

Processing instructions:

1. Choose the right variant: with addition silicones, always use the Grey – for Addition Silicones variant. The coloured variants can inhibit the curing of addition silicones.
2. For modelling, the plasticine is best worked at room temperature.
3. To seal gaps or seams, bring the plasticine to a slightly higher temperature of approx. 25 to 30 °C. The compound is then nice and soft and can easily be pressed into gaps and holes.
4. For repairing or sealing air bubbles, for example in a wax model, the plasticine is best worked at 35 to 40 °C.
5. Unsure about combining it with a particular silicone or casting material? Do a small test on a piece of plasticine first.
6. Residues can be completely melted out in the oven. Never heat above 90 °C and never over an open flame.

Please note

• Only the Grey – for Addition Silicones variant is suitable for addition silicones. If you use a coloured plasticine, the silicone may stay tacky or fail to cure.
• Plasticine is flammable: do not heat it above 90 °C. Melted plasticine can cause burns.
• Not suitable for children under 3 years: small pieces can be swallowed.
• Keep plasticine away from food, drink and animal feed and wash your hands after use.
• Store the plasticine closed, dry and frost-free at 15 to 25 °C, protected from heat and direct sunlight.

Plasticine is supplied under the house brand of Silicones and More, specialists in silicones, modelling and casting materials for makers and professionals.
