Zhermack Silicone Rubber ZA RTV 20-45 is very well suited for the production of demanding, elastic and durable shapes with extensive undercuts.

With Zhermack silicone rubber ZA RTV 20-45 one-piece or multi-piece molds can be produced,
for molding original models made of wood, glass, metal, plastic, wax, ceramic casting compounds.

You can use all water-soluble casting materials such as relief casting compounds such as TFC Xyrarock or Zhermack Elite Rock, Keramin, TFC alabaster plaster, modeling and model building plaster, casting stone, cement, concrete, etc. to cast in the molds that have been produced.
Also soap casting compounds (soap glycerin) for holding your own soap
or waxes for the production of candles are possible without any problems as well as casting with casting resins (resin).
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 2045 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.
