It gives a perfect replica of the original item. Highly resistant in all circumstances and thermo-stable. High mechanical properties, low viscosity and high hardness give very rigid and resistant moulds and high details reproduction. It’s particularly suitable for the production of wax models, even by pressure injection, to realize jewellery and for rapid prototyping.
