ZA 22 Mould (22 ShA)


ZA 22 MOULD is a bi-component addition cured RTV silicone rubber which vulcanizes at room temperature. Because of its considerable fluidity, it is recommended for the duplication of models with many undercuts.

Main application sectors

  • Mouldmaking and model-making due to its considerable precision in reproduction, high dimensional stability and high mechanical resistance
  • Artistic ceramics due to its high dimensional stability, considerable fluidity and good mechanical resistance
  • Concrete moulding
