TROLLFACTORY - Type 1 - Moulding Silicone - 500g
TFC Silicone Rubber Type 1 Moulding Silicone soft 1:1 NV Troll Factory RTV
Addition-curing 2-component silicone rubber that cures at room temperature
TFC Silicone Rubber Type 1 is ideal for producing sophisticated, elastic and durable moulds with pronounced undercuts.
TFC Silicone Rubber Type 1 can be used to produce single- or multi-part moulds,
for casting original models made of wood, glass, metal, plastic, wax or ceramic casting compounds.
You can cast in the moulds produced using all water-soluble casting materials, such as
relief casting compounds like Stewalin, Plastalin Super, Keraflott or plaster, Keramin, Alabit, modelling and model-making plaster, casting clay, cement, concrete, etc.
Soap casting compounds (soap glycerine) for making your own soap
or waxes for making candles are also perfectly suitable, as is casting with casting resins.
In this case, you should pre-treat the mould with a release agent before pouring,
as casting resins can cause the mould to become brittle after repeated use.
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 to use in conjunction with food or for body casting, please ask us.
We also have suitable materials for this in our range.

General application
To produce silicone moulds, you must first determine what you wish to replicate and what casting material the object will be made of. This is of great importance, as there are different types of silicone with varying degrees of hardness and flexibility. Heat resistance is also an important factor. Please refer to the application areas and individual product properties of the silicones in the respective descriptions.
Once you have selected the appropriate silicone, the following materials should be prepared: moulding frame, modelling clay, object to be moulded, pouring container, wooden spoon (or similar), scales, separating vaseline, brush and a knife. Due to the short working times, place these within easy reach right at the start. The moulding frame should then be positioned so that there is at least 2 cm of space between the frame and the object. To seal the mould, roll out a layer of non-hardening modelling clay (e.g. plasticine) onto the base plate; any remaining gaps in the corners must also be sealed. The object can then be brushed with release vaseline and pressed into the compound at the base to secure it.
Next, the selected silicone is mixed in the ratio specified by the manufacturer (usually 1:1 by weight). Using a set of scales, the base (A) and the catalyst (B) can then be mixed in the specified ratio. Both components are then thoroughly mixed together for approx. 1 minute to form a homogeneous mass. The silicone is then poured evenly into the prepared moulding frame.
The final step is curing. Here, the silicone must cure completely within the time specified by the manufacturer, usually at 23°C. Once fully cured, the frame and the modelling clay can be removed. With a soft silicone, the object being moulded can be easily removed from the mould. If a medium-hard silicone has been chosen, it may be necessary to cut it with a knife. The resulting gap can be sealed with rubber during the subsequent casting process. The cured silicone mould can now be filled with various casting materials. These vary depending on the type of silicone rubber selected. Examples include ceramics, plaster, concrete, tin, foodstuffs, etc.
