TFC silicone rubber type 3 is very suitable for the production of heat resistant molds (short term, at the time of casting, no permanent temperature resistance) for casting with low melting metals.
At the same time, the shapes are elastic, wear-resistant and also suitable for displaying undercuts.
TFC silicone rubber type 3 can be used to produce molds with one or more parts
For forming original models made of wood, glass, metal, plastic, wax, ceramic molding.
Fabricate molds for casting with all water-soluble casting materials such as Stewalin, Plastalin Super, Keraflott or plaster, Keramin, Alabit, Giesston, cement, concrete, etc.
You can also add low-melting metals.
Care must be taken to ensure that the form is absolutely dry and the shape must be treated with talc as a separating and fluxing agent before each casting. This gives you better pouring results and protects the mold against burns.
These silicones have not been tested for skin and mucosal compatibility or for use in combination with food.
