TFC silicone rubber Type 2-1 is a standard silicone for the production of sophisticated, elastic, and hard-wearing shapes with undercuts. Because of the shore hardness of 35, the silicone rubber Type 2-1 is perfect for larger, self-supporting shapes of all kinds. Unlike the TFC silicone rubber Type 1, the material has a higher degree of inherent stability over longer stretches of the mold. In addition, Type 2-1 has a very long service life.
With TFC Silicone Type 2-1, it is possible to produce both single and multi-part molds. Impressions can be made of original models made of wood, glass, metal, plastic, wax, and ceramic casting compounds. All water-soluble and solvent-containing casting materials can be cast into the molds produced.
The water-soluble casting compounds include, for example, relief casting compounds such as Stewalin, Plastalin Super, Keraflott or gypsum, Keramin, Alabit, modeling and building plaster, cast clay, cement, concrete, etc. For solvent-containing casting compounds, e.g. resin and epoxy resin, the mold should be pretreated with a release agent, since casting resins can lead to embrittlement of the mold after repeated casting. Seed casting compounds (soap-glycerin), for the production of soap or waxes for the production of candles, can also easily be brought into the molds.
Please note that the silicone is not tested for skin and mucous membrane tolerability, nor for use in conjunction with food.
