This is a harder, firmer jewelry molding rubber at lower cost. Econosil is a putty-like material that makes strong, tough rubber molds. Red brown in color, it cuts like butter, gives waxes a high shine finish and requires no messy sprays. Waxes self-release easily. As a result, wax surfaces are shiny and smooth, which means better metal castings.
After vulcanizing, the rubber mold can be cut by the traditional method or even better, using a separating powder such as mica between the two halves before vulcanizing and the mold just splits apart. So, using this way you will save a lot of time and get a mold quickly and safely. Vulcanizes at 330°F - 15 minutes per layer of rubber.
