Herbin, 5 kg Plasticine, hardness grade 55 The modelling clay retains its strength, it leaves no residue when drying, the casting compound does not deform after the model has been created as it has excellent stability. PLASTILIN does not dry in the air: you can work on and change your model as often as you wish. For example, it can be softened with your hands, a heat gun or a hairdryer; it hardens again when cooled in the refrigerator. Packaging: tube, covered inside with sulphurised paper and 2 polypropylene end caps. Plasticine is a very precise modelling paste with a high stability, which also never dries in the air, which has the advantage that it can be worked on and changed as often as necessary. It is also used in industry (automotive, aerospace), for example to create prototypes or impressions. Artists also use plasticine, for example to reproduce models. The precision of the reproduction is accurate to 1/10 mm. Discover numerous references and works on our website: www.plastiline.fr.
