ZA 13 Mould WT 45 Silicone, 13 ShA, Addition Cure

ZA 13 MOULD WT 45 is a two-component RTV silicone rubber, which is especially recommended for making moulds for polyester resins and concrete (concrete jewellery ) casting.


It is also suitable for use with a polyurethane resin, acrylic resin, epoxy resin and vinyl ester resin. Usually, it does not adhere to plasters, coatings, or paints.

Main Application Areas:

mould manufacturing and modelling with significant reproductive accuracy, with high dimensional stability and excellent mechanical performance.


It is used to cast artistic ceramics because it is the best choice for the sampling and reproduction of surfaces with rich detail due to its high fluidity and low viscosity.



Its high tear resistance and tensile strength make it suitable for concrete moulding. Mockup makers and RC builders successfully use this silicone to produce smaller plastic parts with complicated geometry.
