TFC Silicone Rubber Type 2 is very suitable for the production of demanding, elastic and hard-wearing moulds with undercuts.

TFC Silicone Rubber Type 2 can be used to produce single or multi-part moulds,
for moulding original models made of wood, glass, metal, plastic, wax, ceramic casting compounds.
You can use the moulds produced with all water-soluble casting materials such as.
Relief casting compounds such as Stewalin, Plastalin Super, Keraflott or plaster, Keramin, Alabit, modelling and model building plaster, casting clay, cement, concrete, etc.

Also soap casting compounds (soap glycerine) for making your own soap
or waxes for making candles are possible without any problems as well as casting with casting resins (resin).
In this case, you should pre-treat the mould with a release agent before pouring,
as casting resins can lead to embrittlement of the mould after repeated pouring.
Generally, silicone type 2 has a very long service life.

The silicone has not been tested for skin and mucous membrane compatibility or for use in conjunction with food.
If you are looking for silicones that you would like to use in conjunction with food or body impressions, please ask us.
