Silicones are also used to make the master moulds needed to form the gypsum or resin moulds into which high melting alloys like porcelains can be poured.
Zhermack silicone rubber ZA 35 MOLD Shore A hardness 35
Addition-curing 2-component silicone rubber that vulcanizes at room temperature (RTV).
You get the silicone in high-quality plastic squeeze bottles with a dosing cap.
This makes removal very easy and clean. Exact dosing is effortless, as you know it from comparable food packaging, for example and represents a significant improvement over the usual tin cans or wide-mouth bottles.
Features and Application:
- Easy processing
- Problem-free mixing of the components 1:1 by weight
- Very good flowability, mixture is easy to pour
- Crosslinking to resistant, rubber-elastic vulcanizate without heat of reaction
- Short-term temperature resistance up to 150°C
- High tear resistance and high flexibility
- Very high level of detail in the reproduction
- Excellent non-stick effect for easy release of the models
- Use with larger, self-supporting molds for impressions of all kinds

Zhermack Silicone ZA 35 Mold is very well suited for the production of demanding, elastic and durable molds with undercuts.
Zhermack Silicone ZA 35 Mold can be used to produce one-piece or multi-piece molds, for molding original models made of wood, glass, metal, plastic, wax, ceramic casting compounds.
You can use all water-soluble casting materials such as e.g Cast relief casting masses such as Stewalin, Plastalin Super, Keraflott or gypsum, Keramin, Alabit, modeling and model building plaster, casting stone, cement, concrete, etc.
Also soap casting compounds (soap glycerin) for making your own soap
or waxes for the production of candles are possible without any problems as well as casting with casting resin (resin).
Here you should pre-treat the mold with a release agent before pouring,
since casting resins can lead to embrittlement of the mold after repeated casting.
In general, the silicone ZA 35 has a very long service life.
The silicone has not been tested for skin and mucous membrane compatibility or for use in connection with food.
If you are looking for silicones that you would like to use in connection with food or body moulding, 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!
