Zhermack Silicone Rubber ZA RTV 30-45 is very well suited for the production of demanding, elastic and durable shapes with large undercuts.

Zhermack silicone rubber ZA RTV 30-45 can be used to produce one-piece or multi-piece moulds for molding original models made of wood, glass, metal, plastic, wax, ceramic casting compounds.

You can use all water-soluble moulding materials such as relief casting compounds such as TFC Xyrarock or Zhermack Elite Rock, Keramin, TFC alabaster plaster, modelling and model building plaster, cast stone, cement, concrete, etc. in the moulds that are already produced.

In addition, soap casting compounds (soap glycerin) for making your own soaps
or wax for candle making are just as easy to do as casting with casting resin (resin).
Here you should pre-treat the mould with a release agent before casting
since casting resins can lead to embrittlement of the mould after repeated casting.
In general, the silicone ZA 3045 has a very long service life.

The silicone was not tested for skin and mucous membrane compatibility or use in connection with food.
If you are looking for silicones to use in relation to food or body shapes, ask us.
We also have the right materials for this in our range.

TOP quality, you will be amazed!
The silicone is brand new and can be stored for at least one year, NEW!
