silicone rubber
Features and Benefits
Silicone is ideal for making reusable molds. The extremely stable, yet flexible material can be used particularly well in mold and model making. Thanks to the advantageous properties of silicone rubber, even complex objects with multi-dimensional undercuts can be perfectly reproduced in great detail.
DIY! Make your own silicone molds and models
Silicone molds can be made quickly and easily by yourself. The two-component liquid silicone is mixed in the specified mixing ratio and then poured into the intended shape over the object to be duplicated. After curing, the mold can then be filled with the appropriate casting compound.

Silicone rubber type 17
Silicone rubber type 17 RTV NV whitish 100:5 condensation
Condensation-curing 2-component silicone rubber that vulcanizes at room temperature (RTV). You will receive the silicone in an easy-to-handle plastic can or bucket.
Application areas:
Shore hardness 10: soft, very well suited for smaller moulds, eg a coffee mug made of concrete
Shore hardness 20: Degree of hardness, also still soft, well suited for medium-sized molds up to 50cm
Shore hardness 30: Medium degree of hardness, very well suited for large molds, eg garden figures made of concrete, formwork and matrices for tiles or wall designs, sculptures
Silicone rubber type 17 is very well suited for the production of demanding, elastic and durable shapes with pronounced undercuts.
Type 17 silicone rubber can be used to produce one-piece or multi-piece molds for molding original models made of wood, glass, metal, plastic, wax, or ceramic casting compounds.
You can use all water-soluble casting materials such as relief casting compounds such as Stewalin, Plastalin Super, Keraflott or plaster, keramin, Alabit, modeling and modeling plaster, casting stone, cement, concrete, etc. to cast in the molds that have been produced.
Soap casting compounds (soap glycerin) for making your own soap or wax for making candles are also possible without any problems, as is casting with casting resin (resin).
Due to the longer processing time and the high resistance, silicone type 17 is preferably used for molding larger models (garden figures, tiles) or for casting with more aggressive materials such as concrete.
Due to its property as a condensation-crosslinking silicone, any inhibition problems are significantly minimized.
Properties and application:
- Mix the components 100:5 by weight
- very good flowability, mixture is easy to pour
- whitish (silicone) and transparent (crosslinker)
- Crosslinking to a resistant, rubber-elastic vulcanizate without heat of reaction
- temperature resistant up to 200 degrees Celsius
- High chemical resistance to aggressive components of some types of plastic
- Good tear resistance (abrasion and tearing)
- High level of fidelity in very small details
- High dimensional stability over a long period of time and non-deformable
- Excellent anti-stick effect

That's how it works!
The last step is curing. Here the silicone has to harden completely in the time specified by the manufacturer, usually at 23°C. After final hardening, the frame and plasticine can be removed. With a soft silicone, the mold object can be easily removed from the mold. If you have chosen a medium-hard silicone, it may be necessary to cut it with a knife. The resulting gap can be closed later when pouring with the help of a rubber band. The hardened silicone mold can now be filled with various casting compounds. These differ again according to the type of silicone rubber selected. These are, for example, ceramics, plaster, concrete, tin, food, etc.
