Due to the excellent mechanical properties of the cured rubber as well as its high resistance to casting resin, ELASTOSIL® M4503 is especially suitable for reproducing models with pronounced undercuts in casting resins. Other materials, such as wax and plaster, may be cast without any problems in moulds made from M4503.
