Why silicone is the material of choice for art foundries
Art foundry is a technique used to mold sculptures, usually through the use of lost-wax casting. This centuries-old method, also known as "moulage cire perdue" in French, involves pouring molten metal into a mold that has been created by means of a model. Once the mold is made, the material is filled with wax, which melts away and is replaced by the metal. Different materials can be used to create the model, such as tallow, tar, resins or silicone. Artists work with a multitude of final materials such as aluminum, bronze, or other ferrous and non-ferrous metals. Craftsmen choose these metals for artistic reasons, but also for the compatibility between the different materials and the casting methods they use.
Silicone casting has become one of the preferred materials for creating lost-wax casting models because it is versatile, resistant, easy to use and capable of reproducing the finest details of the original. It is also ideal because of the number of casts that can be made from a single mold. Elkem Silicones has highly dependable products that have a proven track record in lost-wax molding: Bluesil™RTV 3325P + Bluesil™Catalyst 83.
To complete the molding process, Elkem Silicones also offers temperature-resistant silicone oils for the formulation of water-based release agents for aluminum, zamak and magnesium foundry applications.
